Mention three methods of starting squirrel _cage motor?

1. Direct-on-line (DOL) starting: In this method, the squirrel cage motor is directly connected to the power supply without any additional starting equipment. This method is simple and cost-effective but can cause high starting currents and mechanical stress on the motor.

2. Star-delta starting: In this method, the squirrel cage motor is initially connected in a star configuration to reduce the starting current and then switched to a delta configuration for normal operation. This method is more complex and requires a special starter, but it helps to reduce the starting current and mechanical stress on the motor.

3. Soft starter: A soft starter is a device that gradually increases the voltage to the squirrel cage motor during startup, reducing the starting current and mechanical stress on the motor. This method is more expensive but provides smoother starting and better control over the motor's acceleration.
