Problems solved by technology

However, in order to improve the performance of the output torque, the self-contained torque motor is generally designed as a structure with an iron core on the rotor. The rotor iron core is an indispensable part of the magnetic circuit. Therefore, the above design methods and technical measures are not suitable for the whole motor. Magnetic preservation in the whole process of assembly of AlNiCo magnets for mounted torque motors

Abstract

The invention relates to a magnetism-preserving and guiding assembly method of a nickel-cobalt-based magnetic steel self-contained torque motor. During this process, the stator magnetic steel of the motor forms a closed magnetic circuit with the magnet-filled core or the magnetic-preserving bushing or both; 2. Push the motor stator placed in the magnetic-preserving bushing into the magnetic-preserving seat through the positioning lever ; In this process, the stator magnetic steel and the magnetic retaining seat or the magnetic retaining bushing or both constitute a closed magnetic circuit; 3. After removing the magnetic retaining bushing and the positioning operating rod, use the chassis seat to press the motor rotor coaxially It is fixed between the chassis seat and the magnetic retaining seat, and the stator of the motor in the magnetic retaining seat is pressed into the motor rotor by using the stator press-in parts. Or two or three constitute a closed magnetic circuit. The invention realizes the magnetic preservation in the whole process of assembling the alnico type magnetic steel.

Description

technical field [0001] The invention belongs to the technical field of precision assembly of special motors, relates to an assembly technology of a torque motor using AlNiCo magnetic steel, and in particular relates to a method for retaining magnetism and guiding assembly of a nickel-cobalt magnetic steel integral type torque motor. Background technique [0002] NdFeB rare earth magnets have high coercivity, high remanence, and high magnetic energy product. They are the most widely used permanent magnet materials today, but they have obvious thermal expansion coefficient anisotropy, remanence and remanence. Defects such as high temperature coefficient and low Curie temperature. AlNiCo magnets have low coercivity, high remanence, and low energy product, but they have the advantages of isotropic linear expansion coefficient, low temperature coefficient of remanence, and high Curie temperature. Therefore, before the advent of NdFeB magnets, AlNiCo magnets were widely used in p...
