PROBLEM TO BE SOLVED: To obtain a reversible motor provided with a drive device which can rotate the motor at specified speeds regardless of the frequency. SOLUTION: This reversible motor is built up as a permanent magnet synchronous motor, wherein armature windings of different phases constitute a part of a stator and permanent magnets constitute a rotor and is provided with a drive device which is constituted of input terminals 5 connected to a source of AC, a rectifying means 2 which converts the AC voltage input to the input terminals 5 to DC voltage, a converting circuit 3 which converts the DC voltage to a first and a second AC voltage which have the frequency for drive the reversible motor and a phase difference, and output terminals 7 which output the first and the second AC voltage to the armature windings of different phases of the reversible motor 10. |
