Abstract

The invention provides a magnetizing tool of a permanent-magnetic machine and a using method thereof. The magnetizing tool of the permanent-magnetic machine comprises a sleeve, a short circuiting ring, taper keys, taper key dismounting tools and magnetizing coils, wherein one end of the sleeve is arranged on the spindle of the permanent-magnetic machine by a lining ring, and the other end of the sleeve is arranged on a bracket, the short circuiting ring is arranged on the sleeve by supporting rings, taper keys are arranged in the chutes in the short circuiting ring, the taper key dismounting tools are arranged on the end parts of the taper keys and the short circuiting ring, the magnetizing coils are arranged on the magnetic poles above the short circuiting ring, and a tin layer is arranged on the surface of the connecting wire of the magnetizing coil leading-out wires of a pair of adjacent magnetic poles. The magnetizing tool of the permanent-magnetic machine provided by the invention can be used for overcoming the defect in the prior art, the magnetic steel is easy to saturate, the magnetic density is homogeneous, the efficiency is high, the installation and dismounting are convenient, the magnetizing tool of the permanent-magnetic machine are safe and reliable, is strong in generality, simple in manufacturing process and low in cost, and also can be used tautologically and circularly.

Description

technical field [0001] The invention relates to a magnetizing tool for a permanent magnet machine and a use method thereof, which is suitable for magnetizing an outer rotor permanent magnet generator with a large number of poles and a large volume of magnetic steel, and belongs to the technical field of improving the adjustment characteristics of a permanent magnet machine. Background technique [0002] The nuclear power CPR-1100MW national key construction project is equipped with a 5800kW brushless exciter. The permanent magnet machine equipped with this exciter has a large capacity, a large number of stages, and a large volume of magnetic steel. It is the permanent magnet with the largest capacity and largest volume of magnetic steel in China so far. magnetic machine. Therefore, the permanent magnet machine requires large equipment capacity, high ampere-turns for magnetization, many turns of magnetization coils, large inductance, long magnetization time, and difficult to ...
