Ceiling fan motor with generator winding

摘要

A ceiling fan motor with a generator winding is disclosed. A stator is fixed on a motor axle. It is surrounded with several first magnetizing coils, each of which is winded with a second magnetizing coil with a generator winding. A rotor is mounted on the motor axle. The rotor has several magnetic objects around the stator. Each first magnetizing coil is affected by an input voltage to generate an inducing magnetic field for rotating the rotor with respect top the stator. The second magnetizing coil on the stator detects and receives a back electromotive force produced because the rotor rotates and cuts through the magnetic lines, thereby generating electrical power.
