Electronics (DoD): AC Motors

AC Motors

This video demonstrates AC motors in various applications and electronic equipment to emphasize their use and importance. An actual motor is disaassembled to point out each part and the simplicity of construction. The principle of operation is demonstrated, pointing out the magnetic field and magnetizationof the rotor. A rotating magnetic field is produced through a demonostration. Induction from a rotating field to wire loop is demonstrated, followed by an explanation of how the rotor is magnetized. The video concludes with a demonstration of slippage and its relationship to internal and external loading and an explanation of a typical torque curve.
