1, What are aluminum motor housings, or water-cooled motor housing?
Aluminum motor housings, also known as water-cooled motor housings, Cooling motor housings, and aluminum extrusion motor housings.
The water-cooled motor casing is extruded, and cooling water circulates on the inner wall of the casing to take away the heat generated when the motor is running. This process results in almost no heat dissipating from the motor housings to the outside, and water circulation replaces the cooling fan.
The development of aluminum motor casings has successfully replaced the aluminum die-cast motor casings, solving the problems of aluminum motor casings with poor material density and prone to pores and other casting defects. It has successfully avoided the problems of poor surface roughness and poor corrosion resistance of castings. Low defects.
The main applications of aluminum motor housings are starter motors, generators, and micromotors. It is also widely used in water-cooled air conditioning motors, air compressor motors, electric motors, cooling tower machines, gear motors, power tool motors, negative pressure fans, environmentally friendly air conditioning motors, micro-motors, electric tricycle motors, and other fields. With appropriate extruded aluminum housings, these machines and electrical systems achieve maximum efficiency and less energy loss.
