Does induction motor works on DC?

in Electrical Engineering

1 Answer

No, an induction motor does not work on DC (Direct Current). It works on AC (Alternating Current).

Here’s why:

An induction motor operates by creating a rotating magnetic field in the stator (the stationary part of the motor) using AC power. This rotating field induces a current in the rotor (the rotating part), which in turn creates its own magnetic field, and this interaction causes the rotor to turn.

With DC, you don’t get a rotating magnetic field because DC provides a constant, unidirectional current. Induction motors require a changing magnetic field, which only AC can provide.

If you were to try to run an induction motor on DC, it wouldn't work because:

The rotor would not experience any changing magnetic field.

There would be no induced current in the rotor to generate motion.

In summary, induction motors are designed for AC, not DC.
