Description

Description AC energy converter and its driving equipment

The present invention focuses on an induction motor composed of a stator and a rotor, and further develops the function of the induction motor by assembling the stator side and the rotor side as separate and independent devices. In addition to diversifying application aspects, the magnetic generation mechanism and the rotation drive mechanism can be assembled as separate and independent devices, and the application aspects can be diversified as home appliances and industrial equipment. The present invention relates to a novel AC energy converter focusing on the rotation function and its driving device. Background art

In order to efficiently perform power conversion in an induction motor, the magnetic gap between the stator side and the rotor side is usually set to a feasible value of 1 mm or less. This is to assemble the stator side and the rotor side as separate and independent instruments. In the case of assembling the two parts facing each other, the magnetic air gap length is inevitably set to approximately 1. . However, if the magnetic air gap length is set long, the mechanical output decreases. If the input power is increased to compensate for this, the ^ on the stator side generates more heat due to iron loss and copper loss, and as a result, This causes iVi II to lower the mechanical output.

A rotary heating cooker has already been proposed as a close approximation to assembling the rotor side and the rotor side of the present invention into separate separate and independent appliances. ': 8 — 3 5 6 6 4).

The rotary heating cooker is provided with a magnetic generator mechanism (hereinafter referred to as a “stater side”) for generating induction heating or a rotating magnetic field, and a rotating magnetic field generated from the stator side. A pan (hereinafter referred to as the “rotor side”) with a rotatable body or rotor impeller rotatably mounted on a spindle is separated from the stator side. Assembled as a separate device, the rotor side is relatively positioned on the stator side with a magnetic gap therebetween, and the rotating body or rotor is driven to rotate by the rotating magnetic field, and the rotor side is driven by induction heating. It is configured as a device that generates heat and simultaneously stirs food while boiling it.

It is disclosed that in the rotary heating cooker, a coil that generates a magnetic field is divided into a plurality of portions and provided on the stator side. In this coil configuration, the rotor side is driven to be suitable for practical use. It is difficult to apply a rotating magnetic field. In particular, since the rotor side is disposed relatively to the stator side with a large gap, when the rotating magnetic field is to be effectively applied to the rotor side as described above, the coil itself has iron loss and copper loss. I can't control the generation of heat.

Further, it is disclosed that in the rotary heating cooker described above, the rotor side is equipped with a rotating body or a IP rotor provided with a permanent magnet or a magnetized body, but when the permanent magnet or the magnetized body is provided with the rotor, the iron is disclosed. Due to drawbacks such as the ingestion of nails, etc., there is room for improving the rotor side itself for practical use.

Furthermore, non-contact power transmission, which consists of an installation body with a motor stator configuration and a rotating body with a motor stator configuration, where the stator configuration of the installation body and the rotor configuration of the rotation body are magnetically coupled A device has been proposed (Japanese Unexamined Patent Publication No. Hei 8-192924). However, the present invention is conceptual, and is intended only for the structure of a device which is light in weight as a switching regulator, eliminates a power cord, and is easily stored, and lacks practicality. Met.

To provide a new AC energy converter and a driving device for it, which can be configured at a low cost with a simple configuration that is suitable for practical use in terms of cost and can be driven safely. The aim is to provide a simple AC energy converter and its driving equipment. The present invention includes a magnetic generation unit having a combination of materials capable of generating a rotating magnetic field satisfactorily, and a rotating plate having a structure capable of favorably applying the rotating magnetic field during operation. The purpose of the present invention is to provide an AC energy converter configured to drive the rotating mechanism part with high performance and a driving device for the AC energy converter. The purpose of the rotating mechanism part is appropriately set based on the material, shape or configuration of the rotating plate. The purpose is to provide a possible AC energy conversion drive device.

In the present invention, in order to create an application product in which the magnetic generation mechanism unit and the rotation mechanism unit are separated and independent, for example, an application product requiring a rotation control such as a rotary heating cooker, a juicer, a drainer, and a polishing machine. Requires a rotation detector, and methods for obtaining rotation information without contact include, for example, a photoelectric sensor and a proximity sensor.However, a photoelectric sensor has a large sensor element. This is a problem because the space becomes large, and the proximity sensor is susceptible to magnetism.

An object of the present invention is to provide an AC energy converter having a non-interfering rotation detector which solves the above-mentioned disadvantages, has a small installation space, and has no magnetic influence on rotation information.

Conventionally, as an induction motor having a plurality of output shafts, a stator is arranged at the center, rotors are provided on both sides of the stator, and an output # is directly connected to the rotor through the center of the stator. Twin type rotors are also known, but their application range is limited because multiple output shafts cannot be arranged on the same plane.

The present invention solves the above-mentioned drawbacks, and further develops the function of an induction motor that can be assembled as a flat-type separate device in which a stator and a rotor are separated and independent. It is an object of the present invention to provide a thin AC motor having a plurality of output shafts having a simple structure, a small number of parts, and a plurality of output shafts.

Referring to the accompanying drawings, FIG. 1 shows a basic structure of an AC energy converter according to the present invention. This AC energy converter has at least a magnetic generating mechanism section (hereinafter, also referred to as a “stater side”) 1 for generating a rotating magnetic field and a rotating plate 20 supported by a support shaft 21. It is configured to include a rotating mechanism part (hereinafter referred to as “the rotor side” as in 1) 2 which is rotatably supported and separate and independent from the stator side 1.

The rotor side 2 is equipped so as to be driven by a rotating magnetic field generated from the stator side 1 by being disposed relative to the stator side 1 with a magnetic gap G therebetween. In addition, the heat capacity of the coil group installed on the stator side 1 is increased, and the iron loss and copper «I are reduced to a level that can be used J), and the plate shape installed on the mouth side The configuration is such that a closed magnetic circuit can be efficiently formed by generating a secondary magnetic pole by inducing eddy current due to electromagnetic induction with low resistance from the combination. From this basic configuration, the mouth side 2 can be configured as a device having various functions based on a rotary plate as if it were flat.

The stator side 1 is configured so that eddy current loss, iron loss, and copper loss are suppressed, and even if a large amount of magnetic flux is generated, the rotor side 2 can be effectively acted on. In order to embody the configuration, the stator side 1 is assembled with a flat donut-shaped magnetic pedestal 10 as shown in FIG. The magnetic pedestal 10 is preferably assembled by winding a ribbon of silicon steel sheet in a spiral shape. The magnetic pedestal 10 can be configured at a low cost with a simple structure without causing internal distortion. Instead of the silicon steel sheet laminate, a ferrite magnetic material formed and fired can also be used.

On the circumferential surface of the magnetic pedestal 10, a plurality of cored planar rotary drive coils 11 are provided at regular intervals. The number of poles of the rotary drive coil 11 can be appropriately selected as needed, such as four poles, six poles, eight poles, and the like. The rotary drive coil 11 is configured such that the winding 11 a is wound around a magnetic core 11 b formed by laminating a gay steel plate or made of a ferrite magnetic material and separately from the magnetic base 10. The magnetic core 11 b is formed, and the magnetic core 11 b is closely attached to the circumferential surface of the magnetic pedestal 10, so that it can be provided integrally with the magnetic pedestal 10.

Alternatively, when the magnetic pedestal 10 is made of a ferrite magnetic material, the magnetic core is formed integrally with the magnetic pedestal 10 in a protruding shape, and a winding formed by winding in advance is fitted to the magnetic core. And can be provided as a rotation drive coil 11. The magnetic base of the ferrite magnetic material having projections splits formed in approximately 3 equal parts in the circumferential direction, Dekiro also this is integrally formed in combination between its ends by the stepped joints, etc. _c

At that time, the drive coil 11 is a bundle of more than 10 thick and thin wires that can keep the total DC resistance of one phase to 2 Ω or less, preferably 1 Ω or less. Using a single wire formed to be at least the same diameter as the thicker ϊ, Λ, Λ. With this, the magnetic core 11b has 20 to 60% of the coil surface area. It is advisable to assemble one that has a surface area that is large. With this coil configuration, a rotary drive coil 11 can be configured to suppress the heat generation of the coil itself.

The rotary drive river coil 11 is configured by including a two-phase inverter circuit 12 having a transistor for large current control. With the two-phase inverter circuit 12, a simple and inexpensive circuit can be configured. In the two-phase inverter circuit 12, the rotary drive coil 11 is connected in series or in parallel for each phase of sin and cos according to the load requirement. Five

-14-The circuit can be configured to have an electronic switch function.

The two-phase inverter circuit 12 is equipped with a sinZ cos that converts commercial power of 100 V, 50 Hz, Z60 Hz to several tens of amperes or less at 100 V or less, and converts the frequency to 150 to 800 Hz. It is configured to conduct to the rotary drive coil 11 via the two-phase inverter circuit 12. Of course, it has been converted to PWM to increase circuit efficiency. The circuit should be set to generate a frequency current of about 150 to 800 Hz, which is higher than the frequency of the commercial power supply, and practically about 250 to 500 Hz.

In the inverter circuit 12, a kick start function in which a rotating plate on the rotor side 2, which will be described later, is driven by overpower at the time of starting, and after a certain period of time of about several tens of seconds, a steady continuous rotation is performed by a timer operation or the like. The circuit can be configured to have By adding this kick start function, the rotor 2 can be started up to a predetermined number of revolutions in a short time and converted to continuous rotation, and the rotor 2 can be smoothly rotated even under various loads on the rotor 2. It can be done. This function can also be used for emergency stop of reverse rotation mode in overcurrent state during stop operation if only one phase is energized through an inverter circuit of opposite phase: The inverter circuit 12 can include a three-phase inverter circuit depending on the application.

Further, even if the magnetic gap G between the stator side 1 and the rotor side 2 is separated by about 3 to 10mrn based on the configuration of the stator side 1, the rotating magnetic field can be moved from the stator side 1 to the rotor side 2 Therefore, a large starting torque can be obtained on the rotor side 2. Note that this not a stearyl Ichita side 1, the rotor side 2 in one direction only, that by the Hare circuitry for rotating in forward and reverse alternately through Lee Nba Ichita circuit to 18 ^(reversing the signal only a one phase be able to.

Figure 3 shows that the magnetic air gap length between the stator side 1 and the rotor side 2 was set to about 3.5 mm, and the ambient temperature measured according to each input power (Win) during kick start and continuous drive. The rise temperature (T a) of the rotary drive coil 11 at ° C and the starting torque (T s) of the rotor side 2 are shown. The temperature rise (T a) of the rotary drive coil 1 1 is set at the ambient temperature of 40 ° C. It is indicated by a numerical value including the temperature rise of 1.

As is evident from Fig. 3, although the temperature of the rotary drive coil 1] increases during the kick start, a large starting torque can be obtained on the mouth side 2. In addition, at the time of continuous driving, a starting torque sufficiently applicable for practical use can be obtained, and the temperature of the rotary driving coil 11 can be kept lower than the usage limit at an ambient temperature of 40 ° C.

As shown in Fig. 1, the stator side 1 is a flat compact type with each component assembled into a housing case (hereinafter referred to as "steer case") 3. Is configured. The entire stage 3 can be formed of a non-magnetic material such as a non-magnetic plastic material or a calm material (trade name: NDC Co., Ltd.).

And a top plate 32 having heat resistance and insulation. The stator case 3 can be integrally fixed by screwing each part with a tapping screw or the like that is screwed into the top plate 32.

In the stator case 3, the rotary drive coil 11 is bonded and fixed in the holes 31a, 31b ... using an epoxy adhesive having heat resistance and insulation properties. It is better to firmly attach and fix to the frame plate 31 so as to prevent the generation of vibration accompanying the driving of the rotary drive coil 11. In addition, it is preferable to assemble the base 30 with a shield provided inside. The top plate 32 may be provided with one made of a fluorine-based synthetic resin or heat-resistant glass. The bottom of base 30 and the surface of top plate 32 can be provided with ventilation holes for heat release.

The stator section 1 can be provided with an induction heating coil 13 as shown in FIG. This induction heating coil 13 is a flat air-core ring that uses a single wire twisted by bundling several 10 or more thin wires to reduce DC resistance to high-frequency resistance. Formed into What was done may be used.

The induction heating coil 13 is located around the outer periphery of the magnetic pedestal 10, and as shown in FIG. 5, a flange portion 30 b rising on the outer periphery of the recess 30 a in the base 30 of the stator case 3.

It has a 4-pole 2-phase configuration. In addition, a power transmission coil 42 is installed directly above one of the rotation drive coils 11 (located on L4 in Fig. 39).

FIG. 40 is an enlarged view of a portion L 4, and FIG. 41 is a plan view of a rotating plate 20 provided in the rotating mechanism 2. The rotating plate 20 is made of a soft magnetic material, for example, a rotating plate in which a disk made of a steel plate and a disk made of a good conductor (aluminum plate, copper plate) are laminated in two layers, and the disk made of a good conductor is in a cage shape. A rotating coil 20 was provided with a power receiving coil 44 on the surface (surface B) facing the rotating drive coil 11 at a position facing the rotating drive coil. In the present example, as shown in FIG. 41, two receiving coils 44 were provided on a diagonal line of 180 degrees as shown in FIG. Further, a light-emitting element 43 was installed at the center of the rotating plate 20 so as to face the light-receiving element 41 provided in the magnetic generating mechanism 1. Further, the power receiving coil 44 and the light emitting element 43 were electrically connected.

Next, the operation principle of the embodiment will be described. Using the separate AC energy converter shown in Fig. 38, a drive frequency of 500 Hz and a drive power of 200 W (for two phases) were applied to the group of rotary drive coils 11 of the magnetic generation mechanism 1 Thus, the power transmission coil 42 formed a coil by winding a copper wire of 0.05 Φ 100 times. A phototransistor was used as the light receiving element 41 (a phototransistor, a photo thyristor, and the like can be used as the light receiving element). The light receiving element 41 is installed on the rotating plate 20 provided in the rotary drive mechanism 2. The receiving coil 44 obtained was formed by winding a copper wire having a diameter of 0.05 Φ 100 times.

Rotation information transmitted for the first time by transmitting the information to the stator-side receiver as a light emission signal without any interference when transmitting the information from the rotor to the stator. This method is not limited to the present embodiment, and can be applied to a wide range.
