Product name:High temperature stability magnets
The NdFeB magnet properties change as the temperature changes. Ordinarily, when the temperature is up, the magnet properties are down. We use αBr, βHcj measuring the temperature stability of NdFeB magnet.
Model No.TC-ND 105
High temperature stability magnets
The NdFeB magnet properties change as the temperature changes. Ordinarily, when the temperature is up, the magnet properties are down. We use αBr, βHcj measuring the temperature stability of NdFeB magnet.
αBr: Reversible Temperature Coefficient of Br,
Br(20): Br at 20 ℃, Br(T): Br at T ℃
βHcj: Reversible Temperature Coefficient of Hcj
Hcj(20): Hcj at 20 ℃, Hcj(T): Hcj at T ℃
Usually, the industrial standards ofβHcj: is over -0.7%/℃, while theβHcj: of our developed magnet is less than -0.4%/℃, it helps our magnets with excellent temperature stability.
2. Application which needs the high temperature stability
These magnets are mainly used in car motors, EPS, brake motors, servo motors etc.
3. Correlative temperature coefficient data
Grade Serial NO. | Conventional Formula | T-Series | L-TSeries |
αBr | -0.11~-0.128%/℃ | -0.1-0.11%/℃ | -0.09~-0.1%/℃ |
βHcj | -0.6~-0.7%/℃ | -0.55~-0.6%/℃ | -0.4~-0.55%/℃ |
Notes: TheαBr, βHcj is relative to aspect ratio, square degree chart(BH curve) etc. Higher the aspect ratio is, higher the working temperature can be. Our recommended aspect ratio is over 0.5.
The data of a certain grades, please feel free to contact us. Ordinarily, if you have the requests on αBr, βHcj, please inform the details while placing the order. Sample test is needed before mass production.
For more details, please consult our engineer.
