What are the maximum temperature Sintered NdFeB magnets can be used?

Sintered NdFeB magnets can be used What is the maximum temperature?

Magnet maximum temperature depends on the magnetic properties of the Sintered NdFeB magnets itself and operating point selection. In which the operating point of the Sintered NdFeB magnets, the permeability of the Sintered NdFeB magnets can be expressed. The same magnets, the magnetic circuit, the permeability of the higher (ie, the more closed magnetic circuit), the Sintered NdFeB magnets, the higher the maximum temperature, the more stable performance of the magnet. The maximum use temperature of the magnet is not a determined value, but with the degree of change in the closed magnetic circuit. Sintered NdFeB magnets at a given operating point of the premise, the maximum temperature grades are as follows:

Grades NMHSHUHEH

Maximum working temperature ℃ 80100120150180200

If the actual operating temperature is close to the maximum temperature, while there was a substantial m Sintered NdFeB magnets demagnetization, then either the magnetic circuit must be improved in order to improve the magnetic circuit conductivity; either have to choose a higher grade of performance grades, thus ensuring magnets work properly.
