Title:
DEVICE FOR DRIVING STEP MOTOR
Document Type and Number:
Japanese Patent JPS5450914
Kind Code:
A
Abstract:
Linear and rotary stepper motors are provided with predetermined stop positions which differ from the magnetically inherent stepped positions of the stepper motors. The predetermined stop positions result from sensing the distance the rotor or slider is from a predetermined stop position and generating a signal including a position component representing the distance to the stop position and a velocity component representing the velocity at which the stop position is being approached. The signal is in turn utilized to generate a current reference signal for the motor which is compared with the current of the motor so as to stop the motor at the predetermined stop position.
