DRIVING SYSTEM FOR STEP MOTOR

摘要

PURPOSE:To enhance the stop position accuracy of an object to be moved through a step motor without requiring torque increase through scale-up of motor. CONSTITUTION:In the driving system for step motor, sine wave voltage is applied even onto an exciting coil to sustain rotary driving while a maximum pulse voltage is applied on the exciting coil at least immediately before stop of rotation (points of time t13-t14).
