Types of motor windings and technical requirements for welding

The winding is the heart of the motor. The life and operational reliability of the motor mainly depend on the manufacturing quality of the winding and the electromagnetic effect, mechanical vibration and the influence of environmental factors during operation. The selection of insulation materials and structure, insulation defects in the manufacturing process of the winding and the quality of insulation treatment are the key factors affecting the manufacturing quality of the winding. Therefore, in order to ensure the manufacturing quality of the winding, must correctly grasp the winding manufacturing, winding embedded and insulation treatment process essentials, process parameters and process know-how.

I. Classification of windings

1、Categorized by voltage level

Can be divided into high-voltage winding and low-voltage winding. For AC motors, high-voltage winding refers to the voltage level of 3kV and above, a variety of AC stator winding, while other small motors, stator winding, pole winding, DC motor armature winding, etc. are . Belong to the low-voltage winding.

2, according to the location of the winding on the motor can be categorized into stator winding and rotor winding.

Second, the technical requirements of the winding

1, size and shape accuracy

2、Reliability of insulation

3, the firmness of the winding

Reliability of welding quality

Welding is a very important link and process in the motor production and processing. Welding will be directly related to the operation reliability and quality level of the motor. The contact resistance after welding should be small, so as not to cause localized heating, desoldering or broken wires and other accidents.

Hydrogen and oxygen welding machine principle

Hydrogen-oxygen flame welding machine, also known as water welding machine, hydrogen-oxygen machine, hydrogen-oxygen welding machine, is the use of the principle of water electrolysis, electricity will be water (H2O) into hydrogen and oxygen, through the special flame gun ignited to form a hydrogen-oxygen flame, the enameled wire to implement a fast and automatic paint removal welding. Hydrogen-oxygen flame welding has the advantages of smooth and full welding joints, fast welding speed, safety and environmental protection.

Advantages of Walker Energy oxyhydrogen flame welding equipment

● Hydrogen-oxygen flame has a temperature of up to 2,800 degrees, which is one of the highest temperature flames available;

● The calorific value of hydrogen is 34,000 kcal, which is about three times that of liquefied gas;

● Hydrogen flame flame concentration, not dispersion, thermal radiation to be small;

● Hydroxide combustion only generates water, no exhaust gas generation, belongs to the environmentally friendly equipment;

● Hydroxide gas generated by the raw material for water, consume a small amount of electricity, on-demand manufacturing, with as much as much production, no storage of gas, there is no high-pressure explosion and leakage poisoning and other issues;

● Turn on the gas production, shut down the gas, that is, the production of ready to use, do not need to produce;

● Welding motor enameled wire, exempt from the process of removing the varnish, no need to remove the varnish directly welding;

● Welding flame fine, will not produce heat radiation to the neighboring enameled wire;

● Smooth and full welding joints;

● A variety of models of machines to choose from, original spare parts.
