DC Motor Speed Controls

44 products
These controls regulate DC motor speed. They govern adjustable acceleration and deceleration speeds, and they protect the motor from sudden electrical surges. Pulse width modulation (PWM) devices adjust voltage pulses to regulate speed. Silicon controlled rectifier (SCR) controls convert AC voltage to DC voltage and provide variable speed control. These speed controls are used with permanent magnet or shunt wound DC motors, and with DC gearmotors in constant or diminishing torque applications such as conveyors, packaging equipment, and centrifuges.

PWM DC Speed Controls

PWM DC Speed Controls
Pulse width modulation (PWM) devices adjust voltage pulses to regulate the speed of DC motors. They are used for low-voltage devices such as truck-mounted equipment, portable conveyors, and agricultural feeders.

SCR DC Speed Controls

SCR DC Speed Controls
Silicon controlled rectifier (SCR) DC motor controls convert AC voltage to DC voltage, which provides variable speed control for DC motors. They are used in applications such as conveyors, packaging equipment, and centrifuges.
