Title: ELECTRIC MOTOR
Abstract:
In one aspect, an electric motor may include a stator with a stator coil, a rotor with a rotor coil, a control circuit, a brush and commutator, a housing and a shaft. The stator and the stator coil are contained and fixed with respect to the housing, while the rotor and the rotor coil are able to rotate with respect to the housing. The electric motor may further include a rotating coil and a stationary coil to replace conventional brush and commutator. It is noted that an air gap is formed between the rotating coil and stationary coil, so there is no abrasion between these two coils. In another aspect, the motor can be used as a power generator.
