Production process of motor stator with high hardness, high heat dissipation efficiency and high insulation

Abstract

The invention discloses a production process of a motor stator with high hardness, high heat dissipation efficiency and high insulation. The production process comprises the following steps: (1) selecting epoxy potting glue; (2) selecting a plastic mold; (3) selecting glue pouring equipment; (4) pouring glue upwards from the bottom of the plastic mold through glue pouring equipment; (5) placing the plastic mold after glue pouring on a high-frequency vibration machine to vibrate for a period of time, and then taking out a motor stator in the plastic mold; and (6) placing the motor stator in water, introducing 250V direct-current voltage to the motor stator, measuring the insulation resistance of the motor stator, determining that the motor stator is a qualified product if the insulation resistance is greater than 100M ohm, and otherwise, determining that the motor stator is an unqualified product. According to the invention, the thermal conductivity, the wear resistance, the insulatingproperty, the use stability and the use safety of the motor stator are greatly improved, and the percent of pass of the motor stator is greatly improved.

Description

technical field [0001] The invention relates to a production process of a motor stator with high hardness, high heat dissipation efficiency and high insulation. Background technique [0002] External rotor motor with wound assembly as stator. With the advancement of science and technology and the development of society, the requirements of motor equipment for the use of motors are becoming higher and higher. Generally, wound stators are encapsulated by techniques such as dripping paint, plating parylene, and potting glue. Each of the three processes has its own advantages. The cost of dripping paint is low, but its appearance is poor and its insulation performance is average; the price of plated parylene is high, but its insulation performance is excellent, but it is not wear-resistant; the price of potting glue is moderate, and its insulation performance is excellent. When the wound stator has special application requirements such as thermal conductivity, high and low te...

Problems solved by technology

However, the potting glue process is not very mature for motor products, especially for micro and small motors.

Due to its small size, the glue filling space is limited, the glue filling method and effect are not ideal, and the glue layer is uneven

Although the commonly used silicone molds are easy to demould, they cannot guarantee the flatness of the adhesive layer
