💥A three-phase electric motor uses a three-phase power supply to convert electric energy into mechanical energy.
💥It contains four wires (three hot wires and one neutral wire) and uses three alternating currents of the same frequency.
💥Since it generates a rotating magnetic field, it does not need a capacitor for startup.
💥Three-phase AC motors can be divided into three general types: squirrel-cage, wound-rotor and synchronous.
💥Only the squirrel-cage rotor motors and the wound-rotor motors are induction motors.
💥The rotor circuit in an induction motor does not have an external power supply
