Problems solved by technology

However, increasing the magnetizing current will lead to a significant increase in the cost of magnetization, and higher requirements on the performance of supporting devices during magnetization, such as higher performance requirements for capacitors to withstand inrush current, will also increase energy loss, resulting in waste of resources

Embodiment Construction

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the implementation manners in the present invention, all other implementation manners obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0033] It should be noted that when a component is said to be "connected to" another component, it may be directly connected to the other component or there may be an intervening component. When a component is said to be "set on" another component, it may be set directly on the other component or there may be an intervening component at the same time. When a component is said to be "fixed" to another component, it may be di...

Abstract

The invention relates to a magnetizing device, magnetizing equipment, a magnetizing method and a permanent magnet, and the magnetizing device comprises a heating piece, a first magnetic field piece and a second magnetic field piece which are arranged in sequence; one of the first magnetic field piece and the second magnetic field piece is a constant-current magnetic field, and the other one of thefirst magnetic field piece and the second magnetic field piece is a pulsed magnetic field; after being heated by the heating piece, the the to-be-magnetized piece can be magnetized can be magnetizedthrough the first magnetic field piece and the second magnetic field piece in sequence. According to the magnetizing device provided by the invention, the to-be-magnetized piece can be heated and thenmagnetized, the magnetocrystalline anisotropy field of the to-be-magnetized piece can be reduced through heating, and the magnetic field intensity required for the to-be-magnetized piece to reach magnetizing saturation is reduced, so that saturation magnetization of the high-coercivity magnet can be realized under the condition of relatively low magnetic field intensity; besides, the magnetizingdevice provided by the invention reduces the performance requirements on matched devices during magnetizing, and can reduce the energy consumption, thereby reducing the magnetizing cost.

Description

technical field [0001] The invention relates to the technical field of permanent magnet magnetization, in particular to a magnetization device, magnetization equipment, a magnetization method and a permanent magnet. Background technique [0002] The principle of magnetization includes pulse magnetization and constant current magnetization. Pulse magnetization is to pass an instantaneous pulse current in the coil to generate a short super strong magnetic field in the coil, thereby magnetizing the permanent magnet in the pulse magnetic field. For magnets with high coercive force; constant current magnetization is to generate a constant magnetic field through a constant current in the coil, so as to magnetize the permanent magnet in the constant current magnetic field, which is suitable for magnets with low coercive force. [0003] During the magnetization process of a magnet with high coercive force, it is necessary to increase the magnetization current as much as possible, so...
