Abstract:
A fault tolerant virtual elliptical electric motor has at least four coil elements constrained in a stator case. A drive plate is supported by a fulcrum for nutating motion and has at least four core segments each associated with a respective one of the at least four coil elements for attraction upon activation. A control processor provides independent current control to each of the at least four coil elements for activation responsive to a received position command and a received wobble angle input, inducing the at least four coil elements to operate in a pure torque sum configuration upon the drive plate.
