Abstract

The invention provides a permanent magnetic submersible linear motor and a manufacturing method thereof. The permanent magnetic submersible linear motor comprises a mover, a stator and a casing which are sequentially arranged from inside to outside, and resin filling materials are embedded into a gap between the stator and the mover and a gap between the stator and the casing. According to the permanent magnetic submersible linear motor, the gap between the stator and the mover and the gap between the stator and the casing are embedded through the resin filling materials, fully mixing and stirring the filling materials and then embedding the filling materials into the motor stator with an embedding tire are only required in an embedding process, welding during connecting a stainless steel cylinder with a stator core can be avoided, improving safety and quality reliability of the motor is facilitated, moreover, the embedded materials after curing exist in a solid mode, so the motor needs no quite high sealingness, processing precision and dimension requirements of each part of the motor are relatively loose, dimension in the embedding process depends on the embedding tire, and precision is higher compared with the stainless steel cylinder.

Description

technical field [0001] The invention relates to the field of motors, in particular to a permanent magnet oil submersible linear motor and a manufacturing method thereof. Background technique [0002] Permanent magnet submersible linear motors have been more and more widely used in the field of oil exploration, and the harsh environment conditions in oilfields have also put forward higher requirements for the mechanism of permanent magnet submersible linear motors. Due to the high temperature, high pressure and other factors that are not conducive to the operation of the motor in the oil field, the motor itself is required to have the structure and function of high pressure and high temperature resistance. The traditional method is: 1. Strengthen the mechanical strength and sealing of the motor, prevent the motor from structural damage under high pressure to the greatest extent, and prevent the external liquid from entering the inside of the motor; (such as: transformer oil,...
