Examples: Universal motors used in household appliances like
- Q2. Induction motor principle
- Ans.
Induction motor principle is based on the interaction between magnetic fields to produce motion in a rotor.
Induction motor works on the principle of electromagnetic induction.
When an alternating current is passed through the stator windings, it creates a rotating magnetic field.
This rotating magnetic field induces currents in the rotor windings, causing it to rotate.
The speed of the rotor is slightly less than the spee...
