Abstract: 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.

Abstract: An electromagnetic actuator can exert a radial electromagnetic force on a body that is configured to rotate about a rotational axis. The actuator includes a radial control magnetic pole assembly that includes radial control poles adjacent to and spaced apart by air gaps from the body. The actuator includes a permanent magnet (PM) magnetized along the axis, having one pole in contact with an axial face of the assembly and located proximate to a lateral surface of the body. The PM is magnetically coupled to the body in a non-contact manner resulting in a bias magnetic flux in the air gaps. The actuator includes a control coil around the radial control poles located radially outwards from the PM. Electrical current in the coils generates control magnetic flux in air gaps. The non-uniform net magnetic flux distribution around the body results in a radial electromagnetic force exerted on the body.

Abstract: The present disclosure describes a mechanical backup bearing system arrangement to work in conjunction with non-contact magnetic bearings and capable of coping with thermal expansions of the bearing components during operations. Expansions or contractions of an inner or outer race of a bearing can be compensated using particular springs providing a low profile and a proper stiffness. An electric machine system includes a rotational portion and a stationary portion. The electric machine further includes a magnetic bearing configured to support the rotational portion to rotate within the stationary portion. A mechanical back-up bearing resides in a cavity between the rotational portion and the stationary portion. A flat spring is carried by the stationary portion and abutting the back-up bearing.
