DRIVE CONTROL SYSTEM OF STEP MOTOR

PURPOSE:To reduce the size of a step motor by eliminating a current flowed to a phase control transistor at the phase switching time by providing a current/ voltage control transistor, thereby reducing the withstand voltage of the transistor. CONSTITUTION:A current is interrupted by a current/voltag...
