Abstract
Control circuits for reversible DC motors with speed stabilization by the electromotive force are described. Microprocessor-based transistor sensorless drive was developed, characterized by flat loading characteristics, absence of switching contacts for reversal, and possibility of precise setting of speed prior to starting the motor.
