Product Detail
High temperature stability segment magnets are mainly used in car motors, EPS, brake motors, servo motors etc.
1. Motor magnets
2.Good quality
Product name:High temperature stability segment magnets
Model No:ND-ARC201
Model No:ND-ARC201
High temperature stability segment magnets
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
High temperature stability 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.
