This circuit is used inAC/DC general motor thyristor speed adjustment occasions. The armature winding series isconnected to excitation winding, single-phase half wave phase shifting rectifier, and adjusting500Ω potentiometer can change thyristor's control Angle, so that speed is adjusted from 0 to maximum. This circuit is widely used in small household appliances such as blenders, sewing machines, hand drills and woodworking machinery.
