Motor Starting Auto Transformers
Henka’s Motor Starting Autotransformers reduce inrush current while providing high starting torque for large motors. By using reduced voltage taps, they limit initial current draw and gradually increase voltage as the motor reaches full speed. Once at full speed, the autotransformer disconnects, preventing energy loss. Engineered for efficiency and reliability, they ensure smooth motor startups.
Start your motors the right way—smooth, controlled, and without unnecessary power surges for optimal efficiency.
