Dustproof spinning frame motor type spindle based on stator winding and manufacturing method thereof

Abstract

The invention relates to a dustproof spinning frame motor type spindle based on a stator winding. The dustproof spinning frame motor type spindle comprises a motor rotor, wherein the motor rotor is fixed by means of a bearing in an upper sleeve of a spindle blade seat and an axial limit device on a motor end cover; stator cores are fixed on a motor casing at the two sides of the motor rotor; motor windings are wound on the front ends and the rear ends of the stator cores; the shaft extension of the rotating shaft of the motor rotor is directly used as a spindle blade; front end winding end covers are mounted at the front ends of the stator cores; rear end winding end covers are mounted at the rear ends of the stator cores; the front end winding end covers enclose the motor windings at the front ends of the stator cores; the rear end winding end covers enclose the motor windings at the rear ends of the stator cores. The invention also relates to a manufacturing method of the spinning frame motor type spindle. By using the dustproof spinning frame motor type spindle based on the stator winding and the manufacturing method of the spinning frame motor type spindle, the dustproof function of the stator winding is realized.

Description

technical field [0001] The invention relates to the technical field of motor dust prevention, in particular to a spinning frame motor spindle based on stator winding dust prevention and a manufacturing method thereof. Background technique [0002] At present, a motor-type spindle for spinning frames has appeared on the market, which brings more adaptability to the control of traditional spinning frames. In the spinning frame, due to the relatively large dust in the working environment, the spindle motor is a work link that must be protected. The safety and stability of motor operation is directly related to the personal safety of operators, product quality and production efficiency. Therefore, when the spinning frame is working, the dustproof protection of the spindle motor is particularly important. [0003] Existing motor type spindle is made up of spindle rod, spindle rod seat, motor stator and motor rotor etc. (see attached figure 1 ). Wherein, the spindle bar 5 is i...

AI Technical Summary

Problems solved by technology

[0005] Its shortcomings are mainly reflected in: because the spindle needs to run at high speed during work, there must be a gap between the motor rotor and the motor end cover, and the working environment of the spinning frame is dusty and the working time is long

After running for a period of time, the dust will fall into the inside of the motor, which will easily cause damage to the insulation of the motor winding, resulting in motor failure; and may cause winding leakage and sparks that will cause cotton yarn to burn and even endanger the personal safety of the operator

Although the safety of electricity consumption is improved by using 48v voltage at present, it is still difficult to avoid the occurrence of cotton yarn burning phenomenon caused by short circuit of motor winding

In addition, in order to meet the 48v power supply required by the system, the additional power supply cost is also a problem that needs to be considered
