Description

Technical Field

[0001] The utility model belongs to the technical field of motor insulation paper manufacturing, in particular to a motor stator paper feeding device. Background Art

[0002] Insulating paper is a general term for electrical insulating paper. It is used as insulating material for various electrical equipment such as cables and coils. Insulating paper is needed in the production process of motors.

[0003] During production, motor stators use special slot insulation paper of a specific thickness. This can lead to abnormal withstand voltage at the stator wire entry point. Analysis reveals that this is due to damage to the slot insulation paper at the slot opening. To address this issue, increasing the insulation paper thickness is possible, but this significantly increases motor cost. Alternatively, adding a small piece of insulation paper locally at the stator wire entry point can compensate for the damaged slot insulation and completely resolve the withstand voltage issue with only a slight increase in cost. Therefore, a motor stator paper feeding device is provided to address this issue. Utility Model Content
