As shown in Figure, adjusting potentiometer RP can adjust the conduction angle of thyristor, and the output voltage is changed, so as to achieve the purpose of stepless speed adjusting of motor. RP resistance is low,and VS has high breakover angle, high output voltage, then motor has high speed; conversely, the high RP resistance makes low speed of the motor.
