Title:
MAGNETIZING METHOD FOR PERMANENT MAGNET AND MANUFACTURING METHOD FOR HIGH-SPEED ROTOR
Document Type and Number:
WIPO Patent Application WO/2021/196728
Kind Code:
A1
Abstract:
A magnetizing method for a permanent magnet and a manufacturing method for a high-speed rotor. According to the magnetizing method, an included angle between the magnetizing direction of a permanent magnet blank and the geometric axial direction of the permanent magnet blank is detected, and the magnetizing direction of the permanent magnet blank is parallel to the geometric axial direction by machining, to eliminate the deviation of the magnetizing direction of the permanent magnet, and the permanent magnet obtained by the method serves as a motor magnetic core to be applied to the high-speed rotor. The magnetizing method of the permanent magnet serves as part of steps in the manufacturing method for the high-speed rotor, and the manufactured high-speed rotor has the performances of high precision and yield.
