Speed control of a DC motor. | All About Circuits The idea with the analog method is to measure the back emf of the motor and use that to control the speed. This works because there is a unique relationship between the back emf and the motor speed. With a small analog control circuit you can regulate the speed of the motor, so it's not just a control it's actually a speed regulator too. SCR Control circuits Electronic Circuits and Diagrams ... 90° Phase Control of SCR. In ac circuits, the SCR can be turned on by the gate at any angle a with respect to the applied voltage. This angle α is called the firing angle. Power control is obtained by varying the firing angle and this is known as phase control. In the phase control circuit given in fig. 1, the gate triggering voltage is derived from the ac supply through resistors R1, R2 and ... AC Motor Speed Controller Circuit ElectroSchematics This triac based 220V AC motor speed controller circuit is designed for controlling the speed of small household motors like drill machines. The speed of the motor can be controlled by changing the setting of P1. The setting of P1 determines the phase of the trigger pulse that fires the triac. Triac for AC motor speed controller | All About Circuits One thing that may be in play is that the more you have may in fact be a DC motor not an full AC motor which if so your triac control system lacks the needed bridge rectifier to convert the AC to DC. If so you can actually cheat on simplifying your speed controller by using a common light dimmer device ahead of the bridge rectifier as the speed ...
