[QUOTE="Kyle_Keating, post: 6583151, member: 582385"] it works like every other motor in existence, magnet couples to the steel which provides a high permeable return path and there is some air gap at some point in the process. In this case, it’s a straight forward axial motor like 99% of the motors out there. South faces up, North faces down, the magnets are glued to a steel gap plate that is centered around a steel t-yoke. The air gap is between the two. In this case, a single magnet could replace the 6 or 8 smaller disc magnets without changing the geometry of the motor. The smaller magnets are probably chosen for ease of assembly and can also be assembled charged which is much more difficult with a larger single magnet.
