More Information
Summary:Systems, methods, and devices for generating electromagnetic forces may involve generating an axial control magnetic flux in an axial control magnetic circuit comprising a first axial pole, a second axial pole, and an axial actuator target, the axial actuator target coupled to a body having a rotational axis. A radial control flux can be generated in a radial control magnetic circuit comprising a first radial pole, a second radial pole, and a radial actuator target. An electrical compensation current can be applied to an electrical bias flux leveling coil to cancel or nearly cancel any changes of the magnetic flux leaking from either the first or the second axial poles into the radial poles, electrical bias flux leveling coil wound around the rotational axis and located axially between the radial poles and the closest of the first or the second axial poles.
