<P>PROBLEM TO BE SOLVED: To prevent a driving current value and a target current value from deviating from each other at such timing as to reach a conduction completion angle when energizingly-controlling a driving current of a motor to be a target current in a predetermined control period by PWM control, by switching a driving phase of the motor according to a rotational angle of a rotor. <P>SOLUTION: A correction processing part 41b of a control part 4 in an inverter 3 which drives power feeding of a SR motor 1 calculates such timing as to reach a conduction completion angle from a conduction completion angle of a driving phase and a rotational speed of a rotor and corrects a control period so that a driving current value and a target current value meet each other at such timing as to reach the conduction completion angle. <P>COPYRIGHT: (C)2012,JPO&INPIT |
