PM Motor Magnets

Rare Earth magnets (Samarium Cobalt and Neodymium magnets), can be used in magnetic motor and vehicle magnet applications. Rare Earth magnets are typically two to three times stronger than ferrite or ceramic permanent magnets. In electric motors, that results in greater performance from smaller, lighter motors. However, rare earth magnets are also more expensive than ferrite (ceramic) options. The advantages of Our PM Motor Magnet are: 1. High Consistency: The Cpk of Remanence (Br) and Intrinsic Coercive Force (Hcj) are much higher than 1.67. The consistency of the surface magnetic field and magnetic flux can be controlled at +/-1%. 2. High Working Temperature: The neodymium magnets can satisfy the working temperature requirements with excellent temperature resistance. The AH series with 40 kOe super-high coercive force can replace Smco magnets in most applications. 3. High Anti-Corrosion: The perfect coating of magnets can meet many anti-corrosion requirements. The salt spray test and humidity heat test of the high anti-corrosion coating Nickel+ Copper+ Epoxy is typically more than 1000 hours. 4. The super-high magnets have a long lifetime with the following specifications; PCT: 130℃,humidity 100%, vapor pressure 2.7 bar, 20 days, average low weight loss <2 mg/cm2.
