Our country produces the national standard motor housing base is shanxi pingyao, we choose all is the standard component of the housing, its advantage is the appearance, heat dissipation and ensure the processing accuracy.

　　Because of the specification of the housing, the specification of the housing heat sink and high, non-standard electrical housing because the weight of light, so they have to buckle the weight. They are guaranteed to be machined, so they can only be done by cutting back, reducing fin and foot thickness.

　　Due to the thin electric casing, its mechanic precision cannot be completely guaranteed. It is simply shown that the electronic stator is pressed into it. After assembly, the motor cannot start normally or it may be difficult to start. It is considered that the fuselage is too thin to ensure its concentric processing.
