Wipro PARI Diploma Trainee Engineer Interview Questions and Answers

Q1. DC motor working?
Ans. 
DC motor converts electrical energy into mechanical energy through the interaction of magnetic fields.
• DC motor operates based on the principle of Lorentz force

• It consists of a stator (field) and a rotor (armature)

• When current flows through the armature winding, a magnetic field is created which interacts with the stator field to produce rotational motion

• Speed of DC motor can be controlled by varying the voltage or curr...read more
