Definitions
- Scroll compressors have been proposed with protection elements to address this reverse rotation, and other problems.
- the electric motor is often provided with a protector circuit.
- the protector circuit incorporates electronics which respond to excessive current or voltage, and excessive heat.
- the protector circuit is incorporated into the electric motor, and adjacent to the stator windings.
- Protector circuits have been proposed which are placed within the refrigerant flow adjacent to the discharge port. These protector circuits are connected to the electric motor. Should the discharge refrigerant exceed a maximum temperature, the protector circuits will then stop operation of the motor.
- One other prior art system locates a portion of a motor sensor on the non- orbiting scroll. This sensor is then wired into series with the motor protection circuit on the motor. However, the sensor does sense the temperature of the refrigerant in the discharge port. Further, it is undesirable to have two separate protector circuits as the complexity and expense increases.
- a scroll compressor 20 is illustrated in Figure 1A having an electric motor stator 22 and an electric motor rotor 24.
- the rotor 24 drives a shaft 26.
- the shaft 26 drives an orbiting scroll 28 to orbit through an anti-rotation coupling 102.
- the orbiting scroll 28 has wraps 29 interfitting with wraps 32 on a non- orbiting scroll 30.
- the non-orbiting scroll 30 is shown as fixed; however, this invention also extends to non-orbiting scrolls wherein the orbiting scroll is allowed to move through a limited axial distance.
- a separator plate 31 separates the compressor 20 into suction and discharge pressure chambers.
- a crankcase 100 supports the orbiting scroll 28.
- an electric power supply 38 includes three phase power leading to the motor stator 22. As is known, this electric power supply may sometimes be miswired such that the motor would cause the shaft 26 to rotate in the reverse direction from that which is desirable. This is most undesirable for a scroll compressor.
- Figure 3 shows further details including the motor protector circuit 58 positioned within the recess 54.
- the wires 60 extend along a radially outer surface of the non-orbiting scroll to the motor.
- Side walls 62 connect the end wall 56 to an opening 64 in the recess 54.
- the present invention discloses a unique location for the motor protector circuit which allows the system to quickly respond to undesirable conditions in the scroll compressor such as reverse rotation.
- the present invention provides greater assurance that the motor will stop under adverse conditions than the prior art, and further provides a very simple and effective protective circuit.
