Speed Controls, Encoders and Soft Starts

1,828 products found

When you need speed controls, encoders, or soft starts to get the best performance out of your motors, check out Grainger’s wide selection. Motor speed controls are adjustable speed controls for AC, DC, and universal motor applications requiring constant or diminishing torque, such as in fans, blowers, pumps, conveyors, mixers, and more. Drive reactors and output filters help extend the life of motors by reducing heating and audible noise, dampening overshoot peak voltage, and limiting the magnitude of voltage spikes. Using soft starts allows motor current to gradually rise to a steady state and helps reduce start-up motor torque. Encoders track the turning of motor shafts to generate digital position and motion information. Vector motor accessories are designed specifically for use with vector-duty motors and include brakes and encoders. We also have accessories for shaft power monitors.
