Abstract

The invention relates to the technical field of a motor, and solves the technical problem of poor frequency conversion performance of a three-phase asynchronous motor in the prior art. The provided three-phase asynchronous motor comprises a rotor, a stator and a frequency conversion speed regulation mechanism; the rotor comprises a first rotor body and a second rotor body which are symmetrically connected, the stator is located outside the rotor, one end of the stator is connected with an end cover, the end cover is provided with a bearing cover, two end of the rotor are connected with rotary shafts, one side of the rotor connected with the corresponding rotary shaft is provided with a fan, a cover casing is disposed outside the fan, and the cover casing is fixed to the stator; and the frequency conversion speed regulation mechanism comprises a single- and double-layer mixing winding disposed on the stator and a capacitance resistor on a circuit board, the neutral point of the single- and double-layer winding is grounded through a capacitor and a resistor connected in serials, and then the technical effect that frequency conversion performance of the three-phase asynchronous motor can be improved is achieved.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a three-phase asynchronous motor. Background technique [0002] The existing three-phase asynchronous motors all adopt frequency conversion speed regulating mechanism, but the existing frequency conversion three-phase asynchronous motors are prone to resonance phenomenon, thus affecting normal use. [0003] Therefore, there is a technical problem that the frequency conversion performance of the three-phase asynchronous motor in the prior art is poor. Contents of the invention [0004] The invention solves the technical problem of poor frequency conversion performance of the three-phase asynchronous motor in the prior art by providing a three-phase asynchronous motor, and further realizes the technical effect of improving the frequency conversion performance of the three-phase asynchronous motor. [0005] In order to solve the above technical problems, the technical solutions of...
