Title:
DRIVE SYSTEM FOR DOUBLE THREE-PHASE WINDING PERMANENT MAGNET SYNCHRONOUS MOTOR
Document Type and Number:
Japanese Patent JP2018110481
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a motor drive system for driving a double three-phase winding permanent magnet synchronous motor with high efficiency, when the foregoing motor composed of a rotor comprising a permanent magnet and two three-phase windings has a different winding resultant characteristic according to the winding.SOLUTION: There is provided a vector control device 3 constituting a motor drive system together with a motor 1 and an electric power conversion device 2. A command converter 31 for playing a role of producing a d-axis current command value and a q-axis current command value for each of a first winding and a second winding from a torque command value is configured to provide a designated torque, and to simultaneously produce four current command values for minimizing or quasi-minimizing loss generated in the motor.SELECTED DRAWING: Figure 4
