The aluminum shell of blind hole motor refers to the through hole with one end for stator, the other end with bottom plate and bearing chamber and rotor shaft in the middle. This kind of aluminum shell can not be directly heated through the yoke iron. The structure of the motor aluminum shell heater is shown in the figure below. The aluminum shell iron core is heated vertically.

This kind of aluminum shell is generally used for cleaning machines and water pumps. Its main feature is that the two ends of the shell are not connected. We know that the motor shell with the same two ends uses the rocker arm rotary motor aluminum shell heater. The aluminum shell with blind holes like this can only be heated vertically. This heating method is very convenient, fast and convenient.

The blind hole hot sleeve machine quickly heats the aluminum shell by induction, the motor shell expands by heating, and the inner hole expands by the same amount. The assembly with the spindle hot sleeve is smoothly realized. The whole process is simple, time-saving and power-saving.
