aluminium extrusion motor body

Aluminum extension motor body is a device shrouded outside the motor to protect the motor. At the same time, it plays a role in radiating the heat generated by the motor during operation. Generally, there are four kinds of aluminum extension motor bodies on the market: plastic, stainless steel, cast iron and aluminum alloy. The manufacturing of aluminum extrusion motor body is a very important part in motor production. The materials of aluminum extrusion motor body generally include cast iron, cast aluminum alloy, steel pipe, steel plate, etc. The main purpose is to protect the motor from rain, corrosion, rust and other environmental effects.



In terms of heat dissipation performance and cost, plastic has poor comprehensive performance. It is generally used for small built-in pumps with poor quality. Stainless steel is of medium performance and is used in both built-in pumps and external pumps. It is a kind of Aluminum extension motor body with high cost performance, while cast iron is more suitable for submersible sewage pumps, Water cooling is used to cool down. If it is used in an external pump, its heat dissipation performance will be greatly reduced, and the aluminum alloy with good comprehensive performance can use the design of fins to ensure good heat dissipation performance of the motor under dry operation, that is, the price is really expensive.
