A system includes a body (20) having a rotational axis. The system also includes an electromagnetic actuator (12) radially offset from the body (20) and configured to support the body (20) to rotate about the rotational axis. The electromagnetic actuator (12) includes a radial pole assembly (42) magnetically coupled to and cooperating with a radial actuator target (118) to define a radial magnetic control circuit (123), a first axial pole assembly (38) magnetically coupled to and cooperating with a first axial actuator target (92) to define a first axial magnetic control circuit (106), and a second axial pole assembly (40) magnetically coupled to and cooperating with a second axial actuator target (94) to define a second axial magnetic control circuit (116). The structural arrangement of the radial pole assembly (42) and the first and second axial pole assemblies (38,40) is symmetrical about a radial midplane through the radial pole assembly (42), wherein the radial midplane is orthogonal with respect to the rotation axis of the body (20). |
