Description

SINGLE STEP STEPPING MOTOR CONTROLLER ABSTRACT A nonoscillatory single step operation of a stepping motor is obtained by using normal driving circuitry and voltage to start the stepping operation in the desired stepping direction and by simultaneous- ly starting a timer which is adjusted in duration to correspond to the time it takes for the rotor to almost reach the null position. At that time an increased voltage, of the same polarity as the normal stepping voltage, is applied, so as to strongly lock the rotor to the null position with minimum oscilla- tion.
