A representative fault-tolerant rotating electromechanical actuator comprises a permanent magnet synchronous motor with first and second windings that each comprise three phases. First and second voltage source inverters (VSI) provide output signals independently with respect to each other. The first VSI provides output signals to drive the three phases of the first winding, and the second VSI provides output signals to drive the three phases of the second winding. The three phases of the first winding are driven simultaneously with the three phases of the second winding. Control electronics monitor signals associated with the three phases of the windings and detect a fault condition within a first phase of the first winding. The control electronics command the first VSI to drive only second and third phases of the first winding while simultaneously commanding the second VSI to drive the three phases of the second winding.

A drive system for a motor, the drive system comprising:
A motor comprising a first winding and a second winding to be used with a drive system and to be used, at least in part, in an active-active mode, wherein available phases of the first winding and of the second winding of the motor are configured to be driven using signals provided from at least one voltage source inverter of the drive system, and wherein only non-faulted phases of the first winding which are other than the one phase under a fault condition are configured to be driven along with the available phases of the second winding based in part on determination, by control electronics associated with the motor, of the fault condition in the first winding which was performing one phase in the motor.
A plurality of control electronics to control a motor based in part on determination of a fault condition in a first winding performing one phase in the motor and to cause at least one voltage source inverter to drive only non-faulted phases of the first winding which are other than the one phase under the fault condition, and also to drive the available phases of the second winding, wherein the at least one voltage source inverter is to, otherwise, provide signals to drive the available phases of the first winding and of the second winding of the motor in an active-active mode.
A method for a drive system and a motor, comprising:
