<P>PROBLEM TO BE SOLVED: To provide a motor drive controller implementing PWM control for a subject SR motor, which can achieve sufficient torque of the SR motor even in a high-speed range by rapidly activating electric current of a coil in an energization phase from a predetermined energization start timing, with a low-cost configuration. <P>SOLUTION: A control section 4 of an SR motor 1 to be controlled includes an asynchronous energization control section 41c that continuously maintains switching devices Sua-Swa, Sub-Swb in an on-state in an energization path of a coil in an energization phase when activating electric current of the coil in the energization phase from a predetermined energization timing of the coil in the energization phase of the SR motor 1. <P>COPYRIGHT: (C)2012,JPO&INPIT |
