WebAn induction motor with a stationary rotor behaves like a transformer with shorted secondary windings; there is no back-emf to counter the emf in the stator windings, so a very high current flows. As the rotor speeds up, back emf from the rotor causes the stator current to fall – like increasing the resistance on a transformer’s secondary windings.

WebAsynchronous AC motors. Instead of direct current, an AC motor requires three-phase alternating current. In asynchronous motors, the rotor is a so-called squirrel cage rotor. Turning results from electromagnetic induction of this rotor. The stator contains windings (coils) offset by 120° (triangular) for each phase of the three-phase current. Web11 jan. 2024 · Because an induction motor has no brushes, commutator or similar moving parts, it is less expensive to manufacture and maintain than other types of motors. In contrast, consider a synchronous motor. Here, the rotor turns at the same rate — that is, in synchronization — as the stator’s magnetic field.
