Two digital pulse-width modulation motor controls from LCR Electronics, available in battery-powered and ac-line-powered versions, incorporate H-ridge circuitry with high-speed switching to produce precise speed and torque control, bidirectional operation, and overload protection. The high-voltage EC104 and low-voltage EC106, with control methods for either two- or four-quadrant operation, are adaptable to different dc brush, shaded pole, and PSC motor applications including appliances, pumps, compressors, blowers, conveyors, and traction systems. Onboard potentiometer and switch input options are provided for easier human interface. For applications requiring unidirectional dc brush motor operation, the controls can be simplified to eliminate unneeded components. Other options are parking brake, coast, open-loop or closed-loop control, and soft start to extend motor life.
