Controller for multiplex winding motor

摘要

A controller for a multiplex winding motor is obtained whereby when a plurality of multiplex winding motor is driven and controlled by a plurality of inverters, while each winding is composed of a current control system, interference between the current control systems of windings can be compensated. A plurality of voltage non-interacting arithmetic sections is provided for computing a voltage command value supplied to a plurality of voltage applying sections, which are connected to a set of windings, not only by using an output value of a current control section for controlling current in the winding but also using an output value of a current control section 6b for controlling current in another winding, so that voltage interference between the current control sections is compensated.
