As the outer protective shell of the motor, the motor casing can effectively prevent external environmental factors such as dust, moisture, and chemicals from eroding and damaging the internal components of the motor, thereby ensuring the normal operation and long-term stability of the motor. In addition, the motor casing usually also has the functions of heat dissipation and heat preservation. Through the design of the casing and the selection of materials, the temperature inside the motor can be effectively adjusted to ensure that the motor operates within an appropriate operating temperature range. In general, the motor casing plays a very important role in the motor. It is not only used to protect internal components, but also involves mechanical support, heat dissipation, installation and appearance.
