Dec 04, 2014В В· 1) A soft starter might be able to limit the starting current to 100% of FLA, but an AC motor cannot start with that at a fixed frequency. A soft starter works by lowering the voltage only, but the frequency remains the same. Protection Scheme of Single phase Induction Motor. The starter is a device which is used for switching and protecting the electric motor from the dangerous overloads by tripping. It reduces the starting current to the AC induction motors and also reduces the motor torque. Electronic Starter Circuit Working

The motor receives a direct current from a separate source or a DC generator connected to the AC motor shaft. Single-phase and polyphase synchronous motors must be driven or have their rotor connected in the form of a self-starting circuit in order to start. A direct current (DC) single-phase motor starts turning automatically, once electricity is connected, but an alternating current (AC) single-phase motor needs a capacitor to initiate rotation. This is because AC current alternates about 60 times a second, so without a capacitor the motor would simple vibrate rather than rotate.

TL Torque Limiters regulate current on one of the three motor phases to control the torque being applied to the motor, allowing for smooth starting of a motor.
