    Study Notes

    Induction Motors

    • The main advantage of three-phase induction motors in industry is their high efficiency and reliability.

    Stator and Rotor

    • The stator is responsible for creating a rotating magnetic field.
    • The stator has evenly spaced slots that provide a pathway for the windings.

    Rotor Windings

    • The squirrel cage rotor winding is similar to the winding on the stator.
    • The squirrel cage rotor winding is made of aluminum bars shorted together at the ends by two aluminum rings.

    Core Support

    • The laminated core is typically responsible for supporting a hollow, cylindrical core.
