Our company's specification of multi-polar ring magnet can be
reached FB3G/FB3N/FB3X/FB5D/FB5DH. With good surface and quality.
The anisotropic multi-polar ring magnet,CRI type was developed mainly for stepping motor application. It has pole-to-pole oriented crystal grains, and therefore has the highest surface flux density and the largest total flux value among ring shaped ferrite magnets.
These features fit downsizing and/or performance improvement of its
applications such as stepping motors, time-rotors, various types of
Recently , with the development of multi-polar ring magnet, many
manufactures are going to choose multi-polar ring magnets to
instead the segments. For one side, the multi-polar ring magnet
wiil be much steady than the segment. Meanwhile,the cost of
mulitpolar ring magnets will be much lower . What's more ,it will
be more easier than making the combination of the segment in one
motor. So this kind of ring magnets must have a very bright future
in the application fields.
