<P>PROBLEM TO BE SOLVED: To provide a motor control system capable of gaining both of reduction in cogging torque and improvement of motor efficiency. <P>SOLUTION: The motor control system includes a main motor control unit 9 including a control means 8 of generating a motor drive command, a PWM inverter circuit 5a for supplying a drive voltage to a motor 11, and a data communication means 7a of supplying the motor drive command, a sub-motor control unit 10 including a data communication means 7b of receiving the motor drive command from the main motor control unit 9 and a PWM inverter circuit 5b, and a motor 11 with P-pole pairs composed of a stator section where main winding and sub-winding wound around respective salient magnetic poles are axially separated and disposed and the salient magnetic poles of the main winding and sub-winding are shifted in a rotation direction by θ degrees for fixing. The main winding and the sub-winding are connected to the main motor control unit 9 and the sub-motor control unit 10, respectively, the main motor control unit 9 includes a command distributor 4 providing a phase difference to a motor current supplied to the sub-winding for a motor current supplied to the main winding, and the motor drive command drives one motor 11. <P>COPYRIGHT: (C)2011,JPO&INPIT |
