Abstract

The utility relates to a device which conducts heat between motor winding and end closure shell and comprises heat conducting material, winding and end closure shell. The utility model is characterized in that the heat conducting material is arranged between the winding and the end closure shell, which efficiently decreases temperature of the motor, suits for mass produce and is of significant economic benefit and social benefit.

Description

A kind ofly directly motor windings and end cap casing are carried out heat conducting structure
Technical field: the utility model relates to and a kind ofly directly motor windings and end cap casing is carried out heat conducting structure.
Technical background: motor can produce loss in running, and these loss meetings make that the motor feels hot, and temperature raises.If the temperature during the motor operation is too high, insulating material can be accelerated aging and reduce insulation property, even burns out motor, so heating problem is directly connected to the useful life and the reliability of operation of motor.Reduce the temperature rise of motor, improve the cooling condition of motor, the heat of motor internal is distributed quickly.
With regard to motor, winding copper loss and iron core iron loss are the principal elements of motor thermal source.Generally speaking the winding copper loss accounts for 66% in these two principal elements, and the transfer mode of this heat has following three kinds of approach: 1. winding → iron core → air; 2. winding → air → end cap → air; 3. winding → air.This heat is dispersed on every side by conduction, convection current and radiation effects and goes in the coolant, and the pyroconductivity of air is minimum.
The purpose of this utility model provides a kind ofly directly carries out heat conducting structure with motor windings and end cap casing, effectively reduces electric machine temperature rise, makes the running of motor long-term safety.
Summary of the invention: the purpose of this utility model is to realize like this, this structure is made up of Heat Conduction Material, winding, end cap casing, it is characterized in that: between motor windings and end cap casing Heat Conduction Material is arranged, will carry out heat conduction, good heat dissipation effect with Heat Conduction Material between motor windings and end cap casing.
The utility model is simple in structure, and is easy to install, characteristics such as fail safe height.

2-1, Heat Conduction Material 2-2, winding 2-3, end cap casing
Concrete execution mode: the utility model is further described below in conjunction with accompanying drawing
The utility model is a kind ofly directly motor windings and end cap casing to be carried out heat conducting structure in the drawings.This structure is made up of Heat Conduction Material (2-1), winding (2-2), end cap casing (2-3), it is characterized in that: between winding (2-2) and end cap casing (2-3) Heat Conduction Material (2-1) is arranged.During concrete enforcement, between motor windings (2-2) end and end cap casing (2-3), adopt heat conduction, the good Heat Conduction Material (2-1) of insulation property, Heat Conduction Material (2-1) can be according to the required shape of size moulding of motor windings (2-2) and electric motor end cap casing (2-3), with the parcel motor windings, and adopt proper process measures that Heat Conduction Material (2-1) and end cap casing (2-3) are pasted firmly, make winding (2-2), Heat Conduction Material (2-1) and end cap casing (2-3) become as a whole.
The radiating mode of motor windings mainly contained two kinds in the past, the method that the first is traditional, and guaranteeing between motor windings and end cap casing has enough creepage distances, without any material, relies on that air conducts, convection current and radiation.The pyroconductivity of air is minimum in all material, and the motor feels hot and the heat that produces can not distribute effectively, and this kind radiating mode is undesirable, but this kind method row simple in structure, easy, motor quality is easy to control.Another kind method is after motor windings (1-1) end and end cap casing are sealed through mold pressing with plastic packaging material (1-2), make integral body one plastic packaging motor, plastic packaging motor has good insulation performance, heat conductivility, electric machine temperature rise has tangible reduction, but plastic packaging motor has significant disadvantages, and capsulation material is a thermoset plastics, can not degrade, can cause bigger pollution to environment, the quality of motor is wayward in addition, because of motor in aggregates through the mold pressing plastic packaging.Plastic packaging, the thermosets of not degrading will cause serious pollution to environment, and the RoHS of European Union instruction has clear and definite qualification to this, and this type of motor product can not export European Union, and will little by little be eliminated.
