Product Description

Halbach multipole ring magnets, with a maximum performance grade of 50SH, are suitable for micro precision motors, coreless motors and frameless torque motors.

Product Specifications

The magnetic field lines close along the wall thickness, resulting in high material utilisation. The peak surface magnetic flux density reaches up to 6100 Gs, with a THD as low as 1.581 TP3T. No yoke iron is required for magnetic conduction, ensuring an excellent sinusoidal surface magnetic field distribution.

Company Profile

Shenzhen Ruidamei Magnetics Co., Ltd.

The company was established in 2008 and utilises its own patented technology to manufacture radiation- and magnetic field-oriented sintered neodymium-iron-boron magnetic rings, which are widely used in fields requiring precision control, such as robotics, servo systems and automotive electronics. Headquartered in Shenzhen, the company operates production facilities in Jining and Changzhou. In 2026, Zhongxi Kechuang acquired a stake in Ruidamei, providing a significant boost to the company’s future development.
