Available to replace individual arc segments or slabs with multipole ring magnet, extruded neodymium magnets for brushless DC motors come in different sizes. Magnets are made by extruding bonded neodymium compound through die with established ODs and IDs. With isotropic material characteristics, final magnet can be magnetized to any multipole pattern, including skew patterns, either before or after shell assembly. Length can be adjusted to support various motors within frame family.
