Solutions for Motor Drives & Soft Starters

Littelfuse and IXYS Solutions for Industrial Motor Drives and Soft Starters offer protection and control components to help improve motor life and energy efficiency in industrial applications. Variable frequency drives (VFDs) control AC motor speed and torque by varying motor input voltage and frequency. Soft starters offer smooth start and stop operation for a motor. VFDs and soft starters work on the same principles, but they employ different architectures and serve different applications. VFDs can be programmed to vary the speed of the motor based on flow, pressure, and other factors. VFDs are used in elevators, escalators, crushers, mixers, and more. Soft starters get bypassed by a contractor overload circuit as a motor reaches its full speed. Soft starters are ideal for conveyors, pumps, and other belt-driven applications. These Littelfuse and IXYS motor drives and soft starters conform to global and North American safety standards.
