Novel motor wind path structure

Abstract

Disclosed is a novel motor wind path structure. The novel motor wind path structure comprises a machine base, cooling pipes, axial rib plates and an inner fan; multiple axial rib plates are arranged on the inner edge of a cooling cavity at intervals in the circumferential direction; multiple cooling pipes are distributed in a hollow cavity between adjacent axial rib plates; the novel motor wind path structure is also provided with an interval ring, a partition plate and an air blocking cylinder; the partition plate is fixedly arranged on a rotary shaft and positioned on the left end part of arotor axial air channel; the air blocking cylinder is fixed with the axial rib plates, and comprises a first air blocking cylinder and a radially-arranged second air blocking plate; an annular wind screen is arranged on the right side in a position, corresponding to the first interval ring, of the inner fan; the wind screen is fixedly connected with the inner fan and rotates along with the inner fan. The novel motor wind path structure, by virtue of setting of the first air blocking cylinder and the second air blocking plate vertically arranged on the right side of the first air blocking cylinder, and the partition plate and the wind screen, can enable the wind path to be routed in the specific path, so that a stator iron core and windings of motors at the left and right end all can be fully ventilated and cooled, and the cooling effect on the windings and the iron core can be improved.

Description

technical field [0001] The invention belongs to the technical field of motors, and in particular relates to a novel motor air passage structure. Background technique [0002] The motor is a conversion device that converts electrical energy into mechanical energy. The working principle of the three-phase asynchronous motor is to energize the stator, the stator generates a rotating magnetic field, and the guide bars of the rotor cut the magnetic field lines, so the rotor is stressed, and the rotor rotates in the direction of the rotating magnetic field of the stator, and finally passes The shaft extension of the rotor transmits torque, which realizes the process of converting electrical energy into mechanical energy. During normal operation of the motor, there are stator losses, rotor losses, iron core losses, mechanical losses, stray losses, etc., and these losses are ultimately in the form of heat in the motor. form manifested. [0003] The 2-pole and 4-pole synchronous spe...
