Description

Technical Field

[0001] This utility model relates to the field of motor rotor technology, and in particular to an automatic cleaning device for stepper motors. Background Technology

[0002] The motor rotor is a key component of an electric motor. It usually works together with the stator to generate the rotating magnetic field required by the motor. The main function of the rotor is to convert electrical energy into mechanical energy and drive the load through rotational motion.

[0003] In the prior art, patent document with publication number (CN223056277U) mentions a motor rotor cleaning device, belonging to the field of motor rotor manufacturing technology. A motor rotor cleaning device includes a workbench with a support plate mounted on top, and further includes an ultrasonic cleaning chamber and an oven, both fixedly installed on the top of the workbench. A movable block is slidably mounted on the support plate, and an electric push rod is fixedly mounted on the bottom of the movable block. The output end of the electric push rod is connected to a cleaning mesh frame via a bracket. This prior art, through the coordinated use of the movable block, electric push rod, cleaning mesh frame, and ultrasonic cleaning chamber, enables pre-cleaning of the motor rotor before assembly, removing dust, oil, and other contaminants from the rotor surface. This prevents contaminants from increasing the rotor's frictional resistance, ensuring the rotor's operational stability and performance, thereby significantly reducing the probability of malfunctions or damage during motor rotor operation. However, in the aforementioned existing technology, the motor rotor is stored inside the cleaning mesh frame, which can easily create blind spots during cleaning, resulting in low cleaning efficiency.
