<p>Disclosed is a high-power energy-saving motor, comprising a motor and a control circuit therefor. The motor comprises a base (1), a housing (2) and a top cover (3) successively connected to each other, and a stator (4) and a rotor both mounted within the housing (2), wherein a rotary shaft (5) is provided at the centre of the rotor, the rotor comprises an iron core (6), permanent magnet mounting holes are provided within the iron core (6), the permanent magnet mounting holes surround the outside of the rotary shaft (5) uniformly, and a permanent magnet (7) is mounted within each of the permanent magnet mounting holes. The upper and the lower ends of the iron core (6) are provided with an aluminium collar (8), and the aluminium collar (8) is provided with toothed tabs (9). A trumpet-shaped wind suction port (13) protruding towards the iron core (6) is provided on the base (1), a trumpet-shaped wind suction mouth (14) is connected to the back of the top cover (3) via an enclosure (15), and a vent (16) is provided on the enclosure (15). The abovementioned structure improves air convection within the motor, and promotes a wind cooling effect; furthermore, the permanent magnet will not be damaged even after long-term operation, such that operational reliability of the motor can be ensured and the lifetime thereof can be prolonged.</p> |
