Speed Controls, Encoders and Soft Starts
Speed controls, encoders, and soft starts are parts and accessories that help improve motor performance. Drive reactors and output filters extend the life of motors by reducing heat and audible noise, dampening overshoot peak voltage, and limiting the magnitude of voltage spikes. Motor speed controls are adjustable speed controls for AC, DC, and universal motor applications that require constant or diminishing torque, such as fans, blowers, pumps, conveyors, and mixers. Rotary encoders, or shaft encoders, track the turning of motor shafts to generate digital position and motion information. Soft starts reduce the mechanical stress put on a motor at startup for a smoother start. Vector motor accessories, such as brakes and encoders, provide precise control of speed and positioning of vector motors.
