Title: ENERGY SAVING MOTOR
Abstract:
An energy saving motor, comprising a top cover (2), a housing (7), a rotor (5), a stator (6), a bottom cover (8), and an electric energy recovery circuit. The top cover (2) is provided with an air vent (3) and a rotating shaft mounting hole (1); the rotor (5) is provided with a rotating shaft (4); a permanent magnet is provided in the rotor (5); the rotor (5) is provided in the inner circumference of the stator (6) at a particular interval. When electric energy acts on the stator (6), the rotor (5) rotates by means of interaction with the stator (6). The stator (6) is provided with a driving coil (10) and a magnetic induction power generation coil (9) that is provided within the action range of a varying magnetic field generated by the driving coil (10). Varying pulsed electric energy in electronic commutation of the motor passes through the driving coil (10) on the stator (6), the magnetic induction power generation coil (9) generates electric energy, and the generated electric energy passes through the electric energy recovery circuit and then is used, thereby saving energy.
