Squirrel-cage type energy-saving motor

Abstract

The invention relates to the technical field of motors and provides a squirrel-cage type energy-saving motor, which comprises a base, a body, a front end cover, a rear end cover, a rotating shaft, a squirrel-cage type rotor mounted on the rotating shaft, a stator and a winding. An axial fan is mounted on the shaft on the outer side of the rear end cover. An oval fan cover is arranged on the outside of the axial fan. The squirrel-cage type rotor is includes a rotor core formed by stacking a plurality of cold-rolled silicon steel sheets and a squirrel cage. The squirrel cage has a double-layer squirrel cage structure and is composed of two aluminum alloy end rings and a plurality of copper guide bars. The aluminum alloy end rings are provided with two rings of circular through holes in the outer side edge. The copper guide bars are respectively inserted into the circular through holes. The two aluminum alloy end rings are respectively connected with the two ends of the rotor core. The beneficial effects of the invention are that the double-layer squirrel cage structure is arranged to form a stronger magnetic field, the rotor torque and the motor performance can be improved, and the energy-saving effect is better; and in addition, the rotor core is formed by stacking the cold-rolled silicon steel sheets, the iron consumption can be reduced, and the motor efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a squirrel-cage energy-saving motor. Background technique [0002] The squirrel-cage motor has a simple structure. It usually consists of three major components: the casing, the stator poles, and the squirrel-cage rotor. The stator poles are fixedly connected to the casing, and the squirrel-cage rotor and the casing are connected through bearings. This type of motor has many advantages, but There is also the problem of higher energy consumption. Contents of the invention [0003] The object of the present invention is to provide a squirrel-cage energy-saving motor, which can effectively improve the efficiency of the motor and has a good energy-saving effect. [0004] The technical solution of the present invention is: a squirrel-cage energy-saving motor, including a machine base, a body, a front end cover, a rear end cover, a rotating shaft, a squirrel-cage rotor installed on t...
