Double three-phase winding permanent magnet synchronous motor drive system

摘要

PROBLEM TO BE SOLVED: To provide a motor drive system in which each wiring current can be appropriately controlled even when there is a strong mutual inductive coupling between two windings, for a duplex three-phase wiring permanent magnet synchronous type motor composed of a rotor having a permanent magnet and a stator having two three-phase wiring.SOLUTION: A motor drive system comprises; a motor 1; an electric power conversion device 2; and a current control device 3. The current control device 3 is configured using at least a feedback controller 31 and an inter-current type winding non-interference unit 33.SELECTED DRAWING: Figure 6
