Problems solved by technology

During operation, due to electromagnetic effects and thermal effects, it is easy to cause the adhesive to fail, and the magnetic steel will fall off, resulting in equipment failure; the installation with bolts changes the electric field of the rotor, and at the same time, due to eddy current loss, the rotor heats up abnormally and reduces the efficiency of the motor.
Moreover, the above two methods all have low work efficiency, long process cycle, and waste of production cost.

Abstract

The invention discloses a rapid assembly process for surface-mounted magnetic steel of a permanent magnet motor, including a heating process, a set process, a measurement process, a dust removal and cooling process, and a surface-mounted process. The method can not only solve the problem of adhesive failure and magnetic steel falling off; but also avoid bolt installation, reduce rotor eddy current loss, and improve motor performance; use mixed structural adhesive for bonding, improve the magnetic steel assembly efficiency of permanent magnet motor, and improve the performance of the motor. Product performance permanent magnet motor magnet assembly process.

Description

technical field [0001] The invention relates to a quick assembly process of surface-mounted magnetic steel of a permanent magnet motor. Background technique [0002] Existing permanent magnet motor rotor magnets are divided into two types: built-in type and surface-mounted type. Among them, the surface-mounted rotor magnets are traditionally directly bonded to the outer circle of the rotor with an adhesive or installed on the rotor by tightening bolts. During operation, due to electromagnetic effects and thermal effects, it is easy to cause the adhesive to fail, and the magnetic steel will fall off, resulting in equipment failure; the installation with bolts changes the electric field of the rotor, and at the same time, due to eddy current loss, the rotor is abnormally heated and the efficiency of the motor is reduced. And above-mentioned two kinds of methods all have low working efficiency, long process beat, waste production cost. Contents of the invention [0003] The ...
