Abstract
The present disclosure discloses a rapid measuring device and a measuring method for permanent magnet failure temperature. The device includes a measurement system (), an infrared thermal imager (), a vacuum Hall probe () and a laser heating device (). A permanent magnet () is used as a sample. These components work together to achieve rapid and accurate measurement of the failure temperature of the permanent magnet sample (). The present disclosure uses light heating, infrared thermal imaging and surface magnetic field measurement. The heating speed is fast, the temperature measurement is accurate, and the failure temperature measurement of large permanent magnet materials can be achieved.
