Product Specification

TypeRadially Oriented NdFeB Ring MagnetModel40H OD18 × ID10 × H4 mm, 4/6 poles
ParamsBr>1.26T Hcb>939kA/m Hcj>1353kA/m Hk/Hcj>95% (BH)max: 302~326kJ/m3 Max Working Temperature: 120℃MaterialSintered Neodymium Magnet
Applicable Industry1. High-precision magnetic encoders 2. Small industrial BLDC servo motors 3. Magnetic coupler & magnetic transmission assemblies 4. Automotive auxiliary EPS motors 5. High-speed spindle motors for automation equipment 6. Precision magnetic speed sensors

Feature

1. Integrated radially oriented ring, no segment gluing, excellent concentricity and dynamic balance. 2. Uniform sinusoidal magnetic field distribution, low motor torque ripple and quiet operation. 3. Grade options from N42H to N40UH, max working temperature up to 180°C for different thermal requirements. 4. Tight dimensional tolerance ±0.05mm, stable multi-pole magnetic consistency after magnetization. 5. Standard Ni-Cu-Ni coating, great corrosion resistance and long service life. 6. Simplified rotor assembly process, saves assembly cost compared with spliced segment magnets.
