Problems solved by technology
[0003] The difficulty of manufacturing the stator of the magnetic levitation motor comes from the following aspects: 1. The permanent magnet bears a huge alternating force when the stator is running, including the attractive or repulsive force between the rotor and the stator, the thrust or braking force of the motor, etc.; 2. The internal working environment of the machine is full of water vapor, which has an erosive effect on the stator; 3. The stator must be thin enough to compress the installation height of the whole machine; 4. The air gap between the stator and the rotor is usually small, which means that it is difficult to arrange other mechanisms above the stator. Stator for protection
5. It is difficult to make the colloid free of bubbles by using the general glue filling process, and it is even impossible to form a complete film on the surface of the stator

The invention relates to a glue filling method for magnetic suspension motor stator protection. The glue filling method comprises the steps of glue treatment, tool and stator pretreatment, glue mixing, glue filling treatment, curing, demolding and the like. The glue treatment comprises the steps that first glue and second glue are provided and preheated to 80-90 DEG C correspondingly, then the vacuum degree of a material tank storing the first glue is adjusted to 2mba, stirring is continuously conducted till no visible bubbles exist on the surface of the first glue, the vacuum degree of a material tank storing the second glue is adjusted to 5mba, stirring is continuously conducted till no visible bubbles exist on the surface of the second glue, the first glue and the second glue are placed in the material tanks to be stirred, bubbles in the first glue and the second glue can be effectively removed, thus, the bubbles in the glue filling liquid are reduced, and then the probability that air holes are generated in a glue layer formed on the surface of a stator is effectively decreased.
Description
technical field [0001] The invention relates to the technical field of stator glue filling, in particular to a glue filling method for stator protection of a magnetic levitation motor. Background technique [0002] Magnetic levitation motor, special motor with non-contact operation of stator and mover. According to the force of the magnetic field, it is divided into attraction type and repulsion type; according to the degree of magnetic field coupling, it is divided into independent control type of suspension force and driving force and coupling control type of suspension force and driving force; according to the structure of stator and mover, it is divided into magnetic levitation rotation type electric motor and magnetic levitation linear motor. It is used in maglev trains, maglev bearings and maglev artificial heart blood pumps and other occasions. [0003] The difficulty of manufacturing the stator of the magnetic levitation motor comes from the following aspects: 1. T...
