That is why engine speed is slightly less than magnetic field speed ((3000 rpm - 2800 rpm )). Since the magnetic field must rotate faster than the rotor to induce a voltage in the rotor. Present in a magnetic field creates force. Because the cage is short-circuited, the voltage creates a flow of electrical current. Rotation magnetic field” reduces” squirrel-cage, where it induces a voltage. 3 stages generate a turning magnetic field so we don’t require a capacitor on the Three-Phase Motor. The stator is used to generate a magnetic field. The stator is made out of iron core and twisting. ![]() The rotor is usually made as a squirrel-cage, and it is inserted into the stator’s hole. ![]() ![]() Two chief sections of the engine are both rotor and stator. It has quite good efficacy and low manufacture and preserves costs. A Three-Phase Asynchronous Motor is the most commonly used motor on earth.
