Description

Technical Field

[0001] The utility model relates to a direct-drive outer-rotor motor with an in-built drive using an aviation plug. Background Art

[0002] Currently, in the internal structure design of electric rollers, the drive is external and connected through output cables in the output shaft hole. However, the cable ends are prone to damage. Additionally, magnets usually need to be pasted on the steel pipes of electric rollers. Due to the long length of the steel pipes, the process of pasting magnets is complex. Moreover, in the field of electric rollers, the length is a parameter that often changes. Each change will lead to low efficiency and low yield due to changes in the overall installation process. In order to improve the standardization degree, installation speed, and overall integration of electric rollers, it is necessary to design a motor to solve the above problems. Content of the Utility Model
