Bharat Gears Interview Questions, Process, and Tips

Q1. Forword reverse motor circuit diagram .
Ans. 
A forward reverse motor circuit diagram is used to control the direction of rotation of a motor.
• The circuit typically includes a power supply, motor, forward and reverse switches, and possibly a control relay.

• When the forward switch is activated, the motor rotates in one direction, and when the reverse switch is activated, the motor rotates in the opposite direction.

• The control relay may be used to prevent both the for...read more

Q2. Star delta circuit diagram
Ans. 
Star delta circuit diagram is a method used to reduce starting current in induction motors.
• Star delta starter is used for starting induction motors

• In star connection, motor windings are connected in a star configuration for reduced voltage during starting

• After a certain time, the windings are switched to a delta configuration for full voltage operation

• This method helps in reducing starting current and mechanical stress
