Process for fixing resin impregnated adhesive tapes for rotor

Abstract

The invention discloses a process for fixing resin impregnated adhesive tapes for a rotor. In the process, a rotor iron core, a rotary shaft and magnets are adopted, wherein the rotor iron core is formed by laminating a plurality of rotor blades; and a plurality of magnet grooves and non-magnetic grooves are formed on the circumferential surface of the rotor iron core. The process comprises the following steps of: firstly, putting the rotor iron core into a baking oven, and pre-heating the rotor iron core; secondly, uniformly coating glue on the surface of the rotor iron core, and inlaying the magnets into the magnet grooves; thirdly, winding the resin impregnated adhesive tape on the surface of each magnet, and winding an insulating adhesive tape outside the resin impregnated adhesive tape; and finally, putting the rotor iron core into the baking box again, baking the rotor iron core to make the resin impregnated adhesive tape tightly wrap on the surface of the magnet, and thus obtaining a finished product for fixing the resin impregnated adhesive tapes for the rotor. The process for fixing the resin impregnated adhesive tapes for the rotor has the advantages that: the thickness of each resin impregnated adhesive tape can be a fraction of that of metal; an interval between the adhesive tape and the magnet can be quite smaller than the interval between a metal annular ring and the magnet; the friction between the rotor and a stator is greatly reduced; the conduction conversion rate of a magnetic field of a motor is higher; and the rotor can be polished and shaped.

Description

Technical field: [0001] The invention relates to a component fixing process of a servo permanent magnet motor, in particular to a fixing process of wrapping and fixing a rotor with a resin-impregnated adhesive tape. Background technique: [0002] At present, most of the commonly used servo permanent magnet motors adopt the integral rotor structure, and the magnets are attached to the surface of the rotor body. Waste, the strength of the rotor is low. [0003] Usually the fixing process is to fix the magnetic strip on the rotor with a metal ring. It is very difficult to process the metal sheet to be very thin. If the metal sheet is thick, it will affect the output power of the motor. When the metal sheet is running in the motor, the temperature of the motor is usually It will reach about 70 degrees. At this time, the metal sheet will expand due to heat and react, and the conversion rate of the motor magnetic field conduction efficiency is higher. The metal is used to fix the...

[0003] Usually the fixing process is to fix the magnetic strip on the rotor with a metal ring. It is very difficult to process the metal sheet to be very thin. If the metal sheet is thick, it will affect the output power of the motor. When the metal sheet is running in the motor, the temperature of the motor is usually It will reach about 70 degrees. At this time, the metal sheet will expand due to heat and react, and the conversion rate of the motor magnetic field conduction efficiency is higher. The metal is used to fix the magnetic sheet. The process is complicated and it is not easy to be corrected.
