Radial skewed slot rotor and motor applying same

Abstract

The invention discloses a radialskewed slot rotor and a motor applying the same. The motor applying the radial skewed slot rotor comprises theradial skewed slot rotor. Theradial skewed slot rotorcomprises a rotating shaft, a plurality of rotor punching sheets and conducting bars, and the radial skewed slot rotor is mainly formed by coaxially laminating the plurality of rotor punching sheets, wherein a shaft hole is formed in the axis position of each rotor punching sheet, the position of a rotor notch is not changed, the center line of the rotor groove of the outer circle inclines by a certain angle along the radial direction of the rotor punching sheet to form an inclined rotating groove, and the plurality of rotating grooves are uniformly distributed along the circumference. The radial skewed slot rotor and the motor applying the radial skewed slot rotor can be directly applied to an existing asynchronous motor, and compared with an axial skewed slot rotor motor which is widely used at present, the equivalent slot depth and the equivalent guide bar length of the manufactured radial skewed slot rotor motor are reduced, so that the total leakage reactance value of the radial skewed slot rotor motor is reduced, the loss and the size of reactive current in the rotor are reduced, and the effects of improving the efficiency and the power factor and increasing the overload capacity are achieved.

Description

technical field [0001] The invention belongs to the field of motor design, and in particular relates to a radially skewed rotor and an applied motor. Background technique [0002] At present, the asynchronous motor is mainly composed of two parts, the stator and the rotor, and the conversion of electromechanical energy can be realized through the electromagnetic relationship between the two. [0003] The rotors of the existing asynchronous motors are mostly axially skewed rotors. The existing patent with the notification number CN 211508742U may be referred to, which discloses an asynchronous motor with an axially skewed rotor. That is, the rotor slot relative to the stator slot is skewed at an angle in the axial direction, which causes the rotor bar slot or cast aluminum slot of the motor to be non-straight. Under the condition that the fundamental wave chute coefficient is basically unchanged, the tooth harmonic chute coefficient is greatly reduced, so the air gap harmoni...

AI Technical Summary

Problems solved by technology

This kind of axial chute motor has some defects. Because the guide bar is twisted at an angle to make the total length longer, it has a part of chute leakage compared with the straight groove on the basis of other leakage reactances. The leakage reactance of this part of the chute will reduce the efficiency of the motor, reduce the power factor, and deteriorate the overload capacity, thus affecting the overall performance of the motor
