Abstract

The utility model discloses a high stability permanent magnetism synchronous drainage motor, including stator, impeller and permanent magnet rotor, be equipped with outside boss on the stator, be equipped with the rotor shaft on the permanent magnet rotor, the outer end of rotor shaft is connected with the impeller transmission, the inner of rotor shaft stretches into in the boss, still is equipped with the magnet in the boss, magnet and rotor shaft coaxial arrangement; this scheme is through setting up corresponding magnet on the bottom boss of stator for the magnet has the control effect of leading to the axial float of motor permanent magnet rotor through the magnetic force that produces, and then has improved motor permanent magnet rotor job stabilization nature, has improved the life and the friction noise of bearing.

Description

High-stability permanent magnet synchronous drainage motor
Technical Field
The utility model relates to a synchronous drainage motor field, concretely relates to high stability permanent magnetism synchronous drainage motor.
Background
At present, in the permanent magnet synchronous drainage motor on the market, because a negative pressure area is generated around the impeller when the impeller drains water, under the influence of the negative pressure area, the permanent magnet rotor and the impeller of the motor axially move towards the impeller together, the instability of the permanent magnet rotor can accelerate the abrasion and the noise of the bearing, and further the service life of the bearing is shortened.
In patent "motor shaft end support structure and motor" with publication number CN112039277A, a magnetic force mode is adopted to control the axial force between the stator core and the rotor core, so as to restrain the axial movement of the motor shaft and improve the stability of the motor. However, firstly, the solution adopted in this patent is costly and complicated in working operation, requiring lamination of the iron core sheets, and secondly, this patent is applied to asynchronous motors, while synchronous motors are more efficient.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: the utility model aims at providing a can play the axial float of motor permanent magnet rotor and draw the effect, and then improve motor job stabilization nature, improve the life and the high stability permanent magnetism synchronous drainage motor of friction noise of bearing.
The technical scheme is as follows: high stability permanent magnetism synchronous drainage motor, including stator, impeller and permanent magnet rotor, be equipped with outside boss on the stator, be equipped with the rotor shaft on the permanent magnet rotor, the outer end and the impeller transmission of rotor shaft are connected, in the boss was stretched into to the inner of rotor shaft, still was equipped with the magnet in the boss, magnet and the coaxial setting of rotor shaft.
Preferably, the magnet is a cylindrical magnet.
Preferably, the boss is provided with a groove, and the magnet is positioned in the groove.
Has the advantages that: compared with the prior art, the utility model, its advantage that has: the corresponding magnets are arranged on the bosses at the bottom of the stator, so that the magnets have a function of restraining axial movement of the motor permanent magnet rotor through generated magnetic force, the working stability of the motor permanent magnet rotor is improved, and the service life and the friction noise of the bearing are improved.
