SenLong has developed a unique hot extrusion process to produce radially oriented anisotropic NdFeB
Ring magnet. Various magnetic pole distributions. Ring magnets have the highest level of energy,
High heat resistance, no corrosion from inside the product.
Features
The true radial maximum energy product is 240~400kj/m3 (30~40MGOe)
Full rings are available in a wide range of diameters (min. 5mm outer diameter) and lengths (max. 80mm) for easy assembly
Through the design of the magnetization fixture, various magnetization modes (multi-pole to single-pole, various tilt angles) can be realized
Precise magnetization waveform control (eg rectangular, trapezoidal, sinusoidal) for high power or low cogging
High thermal grades available (up to 180°C)
Inherently better corrosion resistance due to no internal pores
Application field
EPS (Electric Power Steering) motor: Combined with a controlled magnetization waveform, it can
Achieves quiet and smooth turns, producing the natural feel of the car's steering
Servo motor: high power, low cogging, quiet and smooth rotation, suitable for AC/DC servo motors
For industrial robots that require fast and accurate movements.
