Description

Technical Field

[0001] This utility model relates to the field of motor technology, specifically to a unidirectional motor operation device. Background Technology

[0002] In the fabric winding (or roller) process, a motor typically drives the rotation of the fabric winding (or roller) shaft to achieve the winding of the fabric (or roller). However, when the winding process is paused or completed, the motor needs to be braked to stop the winding process and prevent reverse winding. Existing technology generally uses electromagnetic brakes, which are inconvenient to install and require adjustment. After braking, the reverse tension can cause the motor to reverse, leading to loosening of the fabric winding (or roller), requiring maintenance, having a short service life, and affecting the quality of the fabric winding (or roller). Therefore, to avoid the shortcomings of existing technology, it is necessary to improve it. Utility Model Content
