Brushless motor stator remainder palm oil protecting and cleaning methods

Abstract

The invention discloses a brushless motor stator remainder palm oil protecting method. palm oil encapsulating is adopted during protecting, and palm oil is encapsulated through the following steps that (1) hot melting is conducted, specifically, the palm oil is heated firstly, thus two thirds of the palm oil is molten, the palm oil is stirred through a clean stirring rod, and thus the palm oil isin even milk white and thick states; and (2) encapsulating are conducted, specifically, the palm oil in the step (1) is encapsulated into a brushless motor stator, still standing and solidifying are conducted, and encapsulating sealing treatment is completed. The invention further discloses a brushless motor stator remainder palm oil protecting cleaning method. According to the brushless motor stator remainder palm oil protecting method, solid palm oil is used for remainder protecting, thus in the stator production process, especially during overall machining, the situation that metal chippings fall into the stator is avoided, the interior and the exterior of a motor can be cleaned thoroughly in the heating and cleaning processes, the phenomena of a fire disaster and the like threatening to the human safety are avoided, normal operation of the motor is ensured, the problems of motor clamping stagnation, short circuiting and the like caused by remainder are solved, and the product quality is improved.

Description

Technical field [0001] The invention belongs to the technical field of brushless motor protection, and in particular relates to a method for protecting and cleaning brushless motor stator excess palm oil. Background technique [0002] The brushless motor is mainly composed of stator, rotor, printed board assembly, end cover and other parts. The conventional brushless motor stator structure is formed by pressing the armature and the casing in the form of interference fit. For stators with a small base number or a high motor speed, a design structure such as an end ring is required, as follows image 3 Shown. In order to ensure the high stability and reliability of the motor during operation, after the stator is press-fitted, it is necessary to turn the stator inner bore bearing chamber and the end ring inner bore. The machining is completed in one clamping, which can meet the high concentricity. Degree requirements. However, since the inside of the stator is an armature winding, ...

AI Technical Summary

Problems solved by technology

This application uses solid palm oil for excess protection, so that metal debris will not fall into the interior of the stator during the production process, and the inside and outside of the motor can be cleaned during the heating and cleaning process without fire. Ensure the normal operation of the motor, solve the problems of motor jamming and short circuit caused by redundant objects, and improve the quality of the product
