Motor products can not be without motor housing

Now a lot of electronic products have to use the motor, motor products can be said to be everywhere! Like summer fans, air conditioning, television sets, washing machines and so on, they have installed a carefully designed motor! Imagine, these electronic products without the motor will be how? Simple thought after the idea is: it must be a waste, not worth the money!

From the above considerations we can know a lot of electrical appliances do not have no motor, then the motor out of the motor shell can do? From the point of view of the industry, the motor shell does not limit what material, but they play a simple role can be divided into technical and visual effects. The role of the appearance of a certain look, you know, nothing more than a good look. The technical point of view is a lot of, the use of a motor is not the same, the design of the motor shell is certainly not the same! Why? The direct impact factor is how much space the device gives to the motor, and how high the motor will be! A reasonable design of the motor shell has become a successful motor shell manufacturers required course!

First of all, the motor casing is a part of the equipment to prevent the grounding of the motor. A high-speed electric motor if running in a water inside the industry, caused by grounding the consequences of what it is certainly not good as can be imagined, the event will also occur frequently, so for the motor, motor shell is very important!

Before dismantling, use compressed air to clean the surface of the motor dust, and wipe the surface dirt clean; select the motor disintegration of the work place, clean up the site environment; familiar with the motor structure and maintenance technical requirements;

Preparation of the necessary tools for disassembly (including special tools) and equipment; in order to further understand the defects in the operation of the motor, the conditions can be done before the removal of a test. Therefore, the motor load test, a detailed examination of various parts of the motor temperature, sound, vibration, and the test voltage, current and speed, and then disconnect the load, a no-load test alone, measured the no-load current and no-load loss, record; cut off power supply, removal of external electrical wiring that record; suitable voltage megger insulation resistance test. In order to repair the insulation resistance with the last measured value compared to determine the motor insulation insulation and trends, should be measured under different temperature of the insulation resistance value is converted into the same temperature, the general conversion to 75 DEG C; test the absorption ratio K. When the absorption ratio is greater than 1.33, indicating that the motor insulation has not been affected by moisture or humidity is not serious. In order to compare with the previous data, the same temperature should be measured at any temperature;
