Electronic starter will ‘redefine’ motor controls and cut wiring costs by up to 56%
1 April 2025 
Rockwell Automation has launched an electronic motor starter that, it says, will redefine motor controls, simplify panel wiring and cut component and engineering complexities, while offering advanced functional safety. It claims that the starter will cut the number of components by up to 75% compared to previous devices, reduce wiring costs by up to 56%, and allow panel space savings of up to 78%.
The M100 Electronic Motor Starter incorporates a point-on-wave (POW) switching technology which allows precise control of electrical loads by triggering the switching action at the optimal point in the voltage waveform. This results in reduced electrical stress on components, smaller inrush currents and lower electromagnetic interference.
The starter integrates into intelligent motor control set-ups, boosting productivity and reducing downtime. It offers zero stacking with no derating up to 55ºC, providing installation flexibility without compromising performance. Removable terminal blocks, available in screw or push-in versions, add convenience and adaptability. The M100 supports direct-on-line (DOL), reversing and safety functions in the same form factor.
Embedded functions such as electronic overload protection, phase loss detection, phase imbalance monitoring, and weld detection, contribute to safety. With the growing importance of functional safety, the starter includes SIL3-certified models and supports Safe Torque Off.
“Our M100 Electronic Motor Starter represents a significant leap forward in motor starting technology and Rockwell’s motor control portfolio,” says Rockwell’s business manager for industrial components, Bill Meindl. “Its advanced features, including point-on-wave switching technology, significantly boosts productivity while minimising valuable panel space, delivering a powerful solution that aligns with the evolving needs of the industry.”
