Description

Technical Field

[0001] This utility model relates to the field of micro motor stator processing technology, specifically a micro motor stator magnetic circuit laser etching device. Background Technology

[0002] Micromotors are miniature electric motors, also known as small motor devices. They can be categorized by driving method (brushed or brushless) or by application. Structurally, they mainly include components such as the stator, rotor, and housing. Common applications include consumer electronics, automotive, medical equipment, robotics, and aerospace.

[0003] When processing the stator of a micro-motor, magnetic circuits need to be etched onto the surface of the stator to better ensure the motor's magnetic flux. Current etching methods typically use laser etching machines, but these machines offer poor clamping and positioning of the stator, resulting in low processing flexibility and low etching efficiency. Therefore, we propose a laser etching device for the magnetic circuits of micro-motor stators. Utility Model Content
