Transverse motor control apparatus, supplies electricity to motor coil based on detected present position of rotor after lapse predetermined spark-advance time period from present position detection time

摘要

A detector (53) detects the present position of a rotor of a transverse motor (11) in a control apparatus which controls the forward/reverse drive of the motor for reciprocatingly moving a transverse guide. A spark-advance excitation position calculator (55a) supplies electricity to a motor coil based on the detected result, after lapse of predetermined spark-advance time period from the present position detection time.
