Radially Oriented Sintered NdFeB Ring Magnets for brushless DC motor, stepper motor

Our Partner is professional manufacturer of Radially oriented sintered NdFeB ring magnets for DC motor, Radially oriented sintered NdFeB segments magnets, Anisotropy bonded NdFeB ring magnet. Radially oriented sintered NdFeB ring magnets for DC motor is becoming more and more popular for motor (Brushless DC motor, stepper motor etc)  application. It is good opportunity introduce  to motor factory/designer. The maximum BH of product  can be reach 48 MGOe. and can be using in motors and install on rotor as magnetic field, and also can be using in magnetic coupling, magnetic bearing, actuator, magnetic gear/wheel etc. and the advantage include:

  • Assembly is made much easier, installation of one rings than gluing arcs into place and no need to add protecting sleeve, simple and quick.
  • Radial sintering assures no “weak spots”
  • Magnets are multi-poled ring does not compromise the magnetic properties.
  • Magnetizing radially makes for a super strong magnet, provide a possibility of unique design by truly different magnetic circuit.
  • Radial ring directly determines the shape tolerance, the tolerance of outer and inner diameter can achieve ±0.04mm, and has the good coaxiality and verticality.
  • The product can install on the rotor of motor as magnet field and reduce motor weight/size & improve the performance

For  radially oriented sintered NdFeB ring magnet, we can do 3 types magnetized as per customer’s requirement, so we need to know magnetization pattern before offer quotation

Radially Oriented Sintered NdFeB ring magnets for DC motor
  1. Skewed magnetized (muti pole ) , which was show on below picture 1
  2. Straight magnetized(muti pole),  which was show on below picture 2
  3. Uni pole on OD and ID, which was show on below picture 3

Our partner has obtained two national invention patents in production processThe product produce by patent well recognized by many well-known enterprises and sales to customer from domestic and aboard.

Our partner  can produce the magnetic assembly (rotor assembly, magnetic coupling, magnetic bearing, actuator, magnetic gear/wheel etc) by using radially oriented sintered NdFeB ring as per customer’s drawing/requirement

For any further information/inquiry, don’t hesitate to contact us
