PURPOSE:To reduce the vibration and the noise of an induction motor by disposing arm modules provided in the phases of an inverter at an equal pitch in the circumferential direction on an end bracket. CONSTITUTION:Arm modules 11 of a main circuit of an inverter are disposed in the same phase in the circumferential direction at an equal pitch on the end bracket 7 of a motor. The leads (i, j, k) of a stator winding are disposed at the positions substantially corresponding to the positions of the arm modules 11 in the phases in the circumferential direction, and the leads (i, j, k) are connected to the output of the inverter. Power is supplied from the exterior to a terminal board 15. |
