Abstract

The invention discloses a method for protecting excess palm oil in the stator of a brushless motor. The protection uses palm oil potting, and the palm oil potting includes the following steps: (1) hot melting: heating the palm oil to make the palm oil Two-thirds of it is melted, and the palm oil is stirred with a clean stirring rod to make it appear uniform milky white and thick; (2) Potting: Pouring the palm oil in step (1) into the interior of the brushless motor stator, and standing to solidify , the potting and sealing process is completed, and its cleaning method is also disclosed. This application uses solid palm oil for excess protection, so that during the production process of the stator, especially when the stator is machined as a whole, metal debris will not fall into the interior of the stator, and the inside and outside of the motor can be cleaned during the heating and cleaning process. Cleaning is clean, there will be no fire hazards and other phenomena that endanger personal safety, ensuring the normal operation of the motor, solving the problems of motor jamming and short circuit caused by excess materials, and improving the quality of the product.

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 excess palm oil in the stator of a brushless motor. 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 the stator with a small base number or a high motor speed, it needs to be equipped with a design structure such as an end ring, as follows image 3 shown. In order to ensure the high stability and high reliability of the motor during operation, after the stator is press-fitted, it is necessary to turn the bearing chamber of the inner hole of the stator and the inner hole of the end ring. degree requirements. However, since the inside of the stator is the armature winding, if no protective m...
