High efficiency and energy saving motor with inner shielding vent

The utility model provides a high efficiency and energy saving motor with an inner shielding vent. A plurality of vents are processed on the back end cover of a motor fan end. Inner shielding components can be embedded in the vents. The inside and outside of the back end cover are coaxially equipped with inner and outer fans. The forced air cooling system of an overall motor is formed by a motor fan housing, inner and outer fans and the back end cover with in and out vents. On the basis that other parameters are not changed or increased slightly, and compared with our patent technology 'efficient and energy-saving motor with forced internal circulation heat radiation', the temperature rise is reduced by 10K in full load operation.
