August undefined, 2024

Allowing a motor to start slowly creates several major advantages for the system and the bottom line. Reducing the motor’s initial driving force will lower the torque applied to components, increasing the lifespan of shafts, bearings, gears, couplings, etc. Another reason to increase the time for startup is to reduce in-rush current to the motor.
