二重三相巻線永久磁石同期形電動機の駆動システム

摘要

PROBLEM TO BE SOLVED: To provide a motor drive system capable of achieving appropriate control of each winding current even when strong mutual induction exists between two windings, in a double three-phase wound type permanent magnet synchronous motor comprised of a rotor with a permanent magnet and a stator with two three-phase windings.;SOLUTION: A current controller 3 forming a motor drive system together with a motor 1 and a power converter 2 is constituted using a 4×4 current controller 33 capable of executing divided feedback control of d-axis and q-axis high-speed and low-speed mode currents.;SELECTED DRAWING: Figure 5;COPYRIGHT: (C)2019,JPO&INPIT
