Title:
CONTROL DEVICE FOR DYNAMO-ELECTRIC MACHINE AND DRIVE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/213124
Kind Code:
A1
Abstract:
This control device for a dynamo-electric machine controls, for individual phase windings of the dynamo-electric machine, the current used to electrify the phase windings by controlling an inverter that applies voltage to the phase windings, wherein the control device is comprises a control unit that: calculates a voltage command value to be applied to the phase windings so that the phase difference of the harmonic components of the same order with regard to the radial direction magnetic flux density and the circumferential direction magnetic flux density of an air gap section between a stator core and a rotor core of the dynamo-electric machine is a predetermined phase difference target value; and controls the inverter in accordance with the calculated voltage command value.
