The main technical features of the hollow shaft motor are: the motor shaft is a hollow metal tube, and an impeller is installed on the inner wall of the hollow metal tube. The impeller is fixed to the bearing on the inner wall of the tube shaft by welding or other methods. . It is mainly divided into two types: no precision requirements and precision requirements.
No precision requirement means that the dimensional accuracy of the hollow shaft or inner hole of the motor is not high. The inner hole is mainly used for wiring, light transmission, or other media such as air. The design of the hollow shaft motor greatly optimizes the mechanical design, facilitates wiring, and saves design space and production costs.
Hollow shaft motors with precision requirements have very high requirements for the precision of the hollow shaft or its inner hole diameter and thread, mainly because most of these hollow shaft motors are customized to meet the requirements of The need to use third-party trapezoidal screws or ball screws. Such a hollow shaft has higher requirements for the accuracy of the inner hole diameter and thread than ordinary through-type screw motors.
Hollow shaft motors have a wide range of uses and can be used as water pumps, ventilation equipment, booster equipment, small turbine generators, propellers, etc. The advantages are: reducing volume, weight, noise, It has multiple functions in one body, reduces costs, is simple to manufacture, and is easy to use.
