Salient features of the magnetizing fixture design and the evaluation on the effect of additional back iron during in-situ magnetization, the use of laminated back iron v/s solid back iron, conductor location and fixture slot shaping.
An optimally designed motor with isotropic bonded neodymium magnets helps in reducing the motor weight and volume by 50 percent to 60 percent compared with the benchmarked ferrite motor.
This paper presents a manufacturing method called Combustion Driven Compaction (CDC) for the manufacture of isotropic bonded NdFeB magnets (bonded Neo). Magnets produced by the CDC method have density up to 6.5 g/cm3 which is 7-10% higher compared to commercially available bonded Neo magnets of the same shape.
