低热外壳及其在永磁电机上的应用

By sensing temperature changes through the nickel-titanium spring in the low-heat housing structure and dynamically adjusting the position of the heat sink to form a port channel, the problem of insufficient heat dissipation when the motor is overloaded is solved, and the low-heat state of the motor housing and noise control are achieved.

AI Technical Summary

Technical Problem

When the motor is overloaded, the speed decreases, which leads to a decrease in airflow. The heat of the motor casing rises rapidly, which may cause the motor to stall. Existing air cooling solutions are difficult to effectively maintain low-temperature speeds.

Method used

It adopts a low-heat shell structure, including a first cylinder, a second cylinder, a third cylinder and a steel ring. It uses a nickel-titanium spring to sense temperature changes and dynamically adjust the position of the first heat sink to form a channel with only ports, which restricts disorderly airflow and increases airflow speed, thereby improving the heat dissipation effect.

Benefits of technology

Under motor overload conditions, it effectively maintains the motor casing at a low temperature, ensuring heat dissipation, preventing motor stalling, and reducing noise.
