Classification of motor housing

When we talk about the motor shell, we generally refer to the motor shell, and there are certain requirements for it. Motor shells are generally used in equipment with relatively high control requirements and high speed, such as instrumentation, model airplanes, etc. Let's take a look at how the motor housing is classified. According to the materials used and the forming method, it can be divided into: (1) Steel casing, including seamless steel pipes for direct car forming; rolled and welded by key plates, referred to as rolled welding casing, stretched with iron sheet (low carbon steel) Molding and so on. These forming methods are less-cutting, no-cutting processing, suitable for mass production, and have been widely used, especially in the case where the casing is required to be magnetic. (2) Aluminum alloy casing, including aluminum plate stretch forming casing, die-casting aluminum casing, cold extrusion molding and aluminum alloy pipe forming casing, etc. Because of its low density, light weight, and convenient processing, aluminum alloys are widely used. For cold-extruded blanks and turned finished aluminum alloy casing structures, the blanks need aging treatment after cold extrusion. The surface after finishing machining needs to be anodized. (3) Stainless steel casing, including profile car casing, cold extruded casing, etc. It is used for small frame size (below frame 28) micro-control motor, which can ensure the necessary strength, dimensional stability and anti-corrosion Sex is also better. (4) The plastic press casing is a part of the stator double insulation structure in the electric tool motor. In addition, there are different types of chassis without base, chassis with base, square chassis and round chassis. The structural role of the casing includes: supporting the stator core. The rotor assembly is supported by the end cover to be coaxial with the stator assembly. Under normal circumstances, the steel casing not only plays a supporting role, but also a magnetic conductive role; the aluminum alloy casing and the stainless steel casing are not magnetic, only supporting. All motor casings have both protective function and heat dissipation function in structure. The plastic case also has excellent insulation. Generally, the installation is carried out through the spigot of the casing.
