Universal motor control with built in self timer


Posted on Feb 6, 2014

Universal motor control with built-in self-timer. Use this circuit only with motors having commutators. If heavy motor loads are anticipated, use a larger-rated C30B SCR in place of the GE-X1 for SCR2. To increase the time delay increase the capacitance of 01 (courtesy General Electric Company).
