Abstract

Provided is a small motor superior in weight/torque balance. A phase stator 10 and B phase stator 12 are disposed to face each other. A rotor is interpositioned between these stators. Electromagnetic coils @are provided to the stators evenly in the circumferential direction. A permanent magnet is provided to the rotor evenly in the circumferential direction. The exciting polarity of the electromagnetic coil is alternately opposite, and this is the same for the permanent magnet. A signal having a prescribed frequency is input to the A phase electromagnetic coil and B phase electromagnetic coil. The rotor rotates between the stators as a result thereof.
