Description

Technical Field

[0001] The utility model relates to the technical field of magnetizing equipment, in particular to a turntable magnetizing equipment for neodymium iron boron magnets. Background Art

[0002] The last step in the magnet production process is to magnetize the magnet. When the magnet is first produced, it does not have magnetism and must be magnetized by a magnetizer. The principle of the magnetizer is to first charge the capacitor with a DC high voltage and then discharge it through a coil with extremely low resistance. The peak value of the discharge pulse current can reach tens of thousands of amperes. This current pulse generates a strong magnetic field in the coil, which permanently magnetizes the magnet placed in the coil.

[0003] The existing magnetization process is to manually place the magnets one by one in the magnetization mold, and then place the magnetization mold into the magnetization machine for magnetization. However, manual operation is slow and costly, and does not meet the requirements of factory automation production. Utility Model Content
