Motor Controllers Flashcards | Quizlet

The overload protection device in the motor starter detects excessive over-current through the contactor's power control circuit. When an overload condition exists, the overload contacts in the lower power motor control circuit de-energize the contactor. The de-energized contactor opens the power control circuit, which removes power from the motor.

SELECTING THE RIGHT STRATEGY FOR STARTING LARGE …

A soft starter is a thyristor voltage controller to smoothly ramp up the voltage at the motor terminals. Soft starters use a controller that allows a timed ramp of output voltage and current limit. When the soft starter reaches full voltage, the bypass contactor closes. The available motor torque, is proportional to the square of the voltage.

Soft starters vs. VFDs: Which one is right for your ...

Protect the motor: Soft starters protect a motor by minimizing the in-rush starting current it receives, specifically by reducing the voltage applied to the motor. It uses silicon-controlled rectifiers (SCRs) to gate the voltage on and off during the starting cycle. It then switches to line power during the run cycle.
