The invention relates to a high-power energy-saving motor comprising a motor and a
control circuit thereof. The motor comprises a base, a
machine shell and a top cover which are connected in sequence, and also comprises a
stator and a rotor which are mounted in the
machine shell, wherein a rotating shaft is arranged at the center of the rotor, the rotor comprises an iron core, a plurality of permanent
magnet mounting holes uniformly surrounding outside the rotating shaft are arranged in the iron core, and each permanent
magnet mounting hole is internally provided with a permanent
magnet. The upper end and the lower end of each permanent magnet are respectively provided with an aluminum
lantern ring on which tooth sheets are arranged. The base is provided with a horn-shaped exhaust opening protruding towards the iron core, and the back of the top cover is connected with a horn-shaped air suction
nozzle through an encirclement body on which a ventilation opening is arranged. By using the high-power energy-saving motor, the
cross ventilation inside the motor is enhanced, the
air cooling effect is improved, the permanent magnets cannot go bad after long-term operation, the reliability for the operation of the motor is ensured, and the service life of the motor is prolonged. A heavy
transformer for the
control circuit is omitted, therefore, heat sources are reduced, the power source efficiency is increased, and the aims of
electricity saving and energy saving are achieved.
