Anisotropic Multipole Ferrite Ring Magnet

Anisotropic Multipole Ferrite Ring Magnet for motor and rotor, Polar Anisotropic Sintered Hard Ferrite Multipole Rings, Radially Oriented Ring Ferrite Permanent Magnets China Factory

Anisotropic Multipole Ferrite Ring Magnet Part No. MPFAMR + Outside Diameter ( or Customer-made dimension)

The products are with precision size, stable performance, excellent quality products; the diameter is in the range of 10mm-80mm, from 2 poles to 48 poles with variety of specifications,

The Permanent ferrite magnet is made of SrO or BaO and Fe2O3 by ceramic processing technology.The texture is relatively hard, brittle material.According to the different orientation of the crystal , it can be divided into isotropic magnets and anisotropic magnets. Due to the ferrite has good temperature resistance with low cost, which has become one of the most used magnets.

The products of the company are with precision size, stable performance, excellent quality products; the diameter is in the range of 10mm-80mm, from 2 poles to 48 poles with variety of specifications, we can supply sine wave, trapezoidal wave, square wave and other magnetizing waveform. High performance of the products and the surface magnetic flux density can reach from 1200 GS to 2100GS.

The products are widely used in Brushless DC motor, precision servo motor, permanent magnet motor, micro motor, instrumentation, magnetic drive, magnetic therapy devices,etc.

There are multiple ways to make a ring magnet: Polar Anisotropic Multipole Ferrite Ring Magnet
1) Circular where no pole is accessible unless you cut it.
2) Where inner and outer perimeter are poles.
3) Where (if you think washer) the facing surfaces are poles.
4) Where one half circle is north and the other is south.
5) Random polarization as can happen when heated or shocked in a magnetic field including the earth’s magnetic field. Drop a steel washer on a concrete floor or hit it with a hammer and it will become slightly magnetized. Workman often whack their screwdrivers with a hammer pointing them north to magnetize them.
