PROBLEM TO BE SOLVED: To realize low vibration and low noise for a motor having permanent magnets. SOLUTION: This inverter apparatus comprises a motor, in which permanent magnets 150 to 158 of p-poles coils 102, 103, 104 of k-phase are provided through the centralized winding to an iron core 172, having grooves 174a to 1 of the number obtained by dividing a value (p×k) by 2. An inverter circuit 101 supplies a current, to provide the result that a sum of the products between the instantaneous value and current value of no-load inductive electromotive force of coils 102, 103, 104 of each phase. Thereby, the variations in generated torque can be controlled, and moreover low vibration and low noise of motor 100 can also be realized. |
