multi-pole magnets
Permanent magnets are most often two-pole magnetised. A multi-pole magnetic circuit (for example, a PMSM rotor) needs to be assembled from these bipolar magnets. Multi-pole magnets provide a more efficient solution, as they can be magnetised in up to tens of poles. Sintered neodymium magnets are available; they are radially oriented and primarily designed for drives. These magnets are anisotropic, so the radial orientation of the particles takes place during the manufacturing process. Plastic-bonded multi-pole magnets are used in encoders and brakes in addition to drives. These magnets are very often used in the automotive sector, which requires a manufacturing process certified under IATF 16949.
multi-pole sintered NdFeB magnets
Multi-pole neodymium magnets allow for more efficient mounting of the rotating multi-pole body. Instead of assembling from individual segments, multi-pole magnets can be processed very quickly. With regard to costs, this technology becomes economically viable only in larger series.
multi-pole plastic-bonded magnets
This technology allows to efficiently produce a multi-pole magnet, suitable for smaller power drives or for encoders and other sensors using multi-pole magnetic fields.
assistance with development
Helping you find new ways. We can analyse existing solutions. Based on further measurements and modelling, we will design a suitable material and a suitable magnetisation method for the manufacture of the multi-pole magnet.
we focus on
- supply of magnets for electric motors
- supply of magnets to the automotive industry (IATF 16949)
- development of new applications
