What is the function of the motor housing?

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.

What are the requirements for the design of the cooling channels in the motor housing?

The design of the motor housing and cooling channels is critical to the operation of the motor drive, while optimizing the channel design can also improve cost-effectiveness, and its design and optimization are generally achieved through simulation analysis.

The complex geometry of cooling channels (serpentine or helical) poses challenges for the production of housings for integrated electronics. With the aid of fluid dynamics (CFD) calculations, the optimal solution is studied, and CFD simulation has the advantage of reducing development time. And the flow calculation shows that the efficiency of the cooling channel is not affected by the design. The c variant calculates the results of a helical cooling channel with a larger cooling surface and increased turbulence of the cooling medium, improving heat transfer. But its disadvantage is that the temperature gradient on the longitudinal axis of the motor exceeds 30K.

What are the production conditions of the motor housing?

The production of castings takes place in a fully equipped foundry. To meet strength requirements, parts are cast under vacuum and then heat treated. One challenge for casting technology is the inner shell sealing surface. The nearly porosity-free surface of the motor housing requires an extremely narrow process window. In addition to meeting these porosity requirements, special attention must be paid to product handling after machining due to tight dimensional tolerances.

In addition to the two-piece design of the motor housing described above and established in series production, different designs have also emerged for future motors. The clear trend towards increased integration of the latest generation of electric drives, such as electronic systems, electric motors and gear positions in a one-piece housing, makes the die-casting process method suitable for process requirements. Therefore, the complex product design and cooling structure make low pressure die casting and CPS sand core casting as the process options to enter the shortlist.

What is the function of the motor housing?

Motor housings are devices that protect the internal DC motor body from dust and damage. These motor housings also provide reliable and consistent functionality and ideal performance for the motor. These motor housings are manufactured using a top quality material, making them robust and durable. These motor housings have an excellent shape and size to easily and reliably mount the motor in them and can be further adjusted in the most desirable and desired manner.
