TOPOLOGIES TO REDUCE FORCE RIPPLE FOR PROPULSION MOTORS
Various topologies to reduce force ripple for propulsion motors are provided. A propulsion motor comprises: ferro-magnetic cores arranged along a movement axis, the ferromagnetic cores including one or more end ferromagnetic cores located at an end of the movement axis, the one or more end ferromagnetic cores shaped to provide one or more of increasing magnetic permeance or decreasing magnetic reluctance from the end of the movement axis towards a center of the movement axis; armature coils located around the ferromagnetic cores; and at least one field coil around one or more of the armature coils and the ferromagnetic cores.
