Abstract

The invention relates to the technical field of motors and provides a heat-radiating three-phase asynchronous motor. The heat-radiating three-phase asynchronous motor comprises a rotor, a stator and a frequency conversion speed control mechanism. The rotor comprises a first rotor and a second rotor which are symmetrically connected. The stator is positioned outside the rotor, and one end of the stator is connected with an end cover. The end cover is provided with a bearing cap. Two ends of the rotor are connected with rotating shafts. One side, connected with the rotating shaft, of the rotor is provided with a fan. The fan is externally provided with a cover housing. The covering housing is fixed on the stator. The fan comprise a shaft sleeve connected with the rotating shafts, a base outside of the shaft sleeve, and blades arranged on the base. The blades are arranged on the base in an arc form. The frequency conversion speed control mechanism comprises a single and double layer winding arranged on the stator and a capacitive resistor on a circuit board. A neutral point of the single and double layer winding is grounded through a capacitor and a resistor which are connected in series, so that the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a heat-dissipating three-phase asynchronous motor. Background technique [0002] The existing three-phase asynchronous motors all adopt frequency conversion speed regulation mechanism, but the existing frequency conversion three-phase asynchronous motors are prone to resonance phenomenon, which affects normal use. Due to the poor frequency conversion efficiency, the work efficiency is low, which affects heat dissipation . [0003] Therefore, the three-phase asynchronous motor in the prior art has the technical problem of low working efficiency. Contents of the invention [0004] The invention solves the technical problem of low working efficiency of the three-phase asynchronous motor in the prior art by providing a heat-dissipating three-phase asynchronous motor, and further realizes the technical effect of improving the working efficiency of the three-phase asynchronous motor....
