Motor control

Motor control has always been something difficult to tackle with as a motor is first of all an inductive type of load with high starting currents (which doesn’t help reduce size and costs of protection devices like fuses) and over voltages generated at turn-off. This is why Solid State solutions are more and more popular to control motor loads. Another big advantage of using power electronics is that numerous control modes can easily be performed thanks to very fast response time, and computing power of micro-processors. celduc relais specialising in Solid State Relays manufactures in France with a high level of quality a complete range of Solid State Contactors for motors, as well as soft starters and motor reversers.
