Aluminum motor housing is generally cast iron (pig iron) casting, you can use the angle grinder in the crack grinding V bevel, and then welded with cast iron welding rod. This can only be an emergency, in the long run, it is better to replace the housing, so as to avoid the motor in operation, the occurrence of "rolling package" (housing and stator wire package, the position of movement, the motor wire package lead wire yanked off), resulting in motor damage and scrap.

motor housings are generally used to refer to the external housing of all electrical motor equipment. The motor housing is a protective device for the motor and is made of silicon steel and other materials by stamping and deep drawing processes. In addition, the surface of the anti-rust and plastic spraying process can well protect the internal equipment of the motor. The main function: dustproof, noise proof and waterproof.

Conventional Motor Housings are usually made of cast or forged metal. Metals used in housings include steel or corrosion resistant alloys. The damping characteristics, weight and other properties of the housing are a function of the materials used to construct the housing and the geometry of the motor structure.

Since the manufacturing materials of different aluminum motor casings will have different technical standards, it will be more guaranteed to choose according to actual needs, especially in terms of use effects, there will be very stable performance. According to actual needs, materials from well-known manufacturers are of better quality and more compliant.

The aluminium housing motor is known as a green product in the motor industry due to its low pollution and is favoured by more and more countries, especially in the more economically developed countries where aluminium housing motors have become quite popular.
