Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a motor self-locking mechanism with a limiting function. Background Art

[0002] An electric motor, commonly known as a "motor", is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. It is a common electrical device and is widely used in our daily lives. Basically, any electrical appliance that can generate kinetic energy has a motor. As the application scenarios of motors continue to change, the requirements for motors are also increasing. In order to enable the drive shaft of the motor to stop rotating quickly and stably, most of the time, an electromagnetic brake mechanism is set at the end of the motor to assist the drive shaft of the motor to stop rotating and achieve motor self-locking.

[0003] At present, when the motor is self-locked, the electromagnetic brake mechanism is too complicated, which occupies a large space and makes the motor production cost relatively high, and it is impossible to limit the stopping position of the motor. For this reason, we propose a motor self-locking mechanism with a limit function. Utility Model Content
