Abstract: A permanent magnet machine includes a machine housing having an inner surface that extends between a first housing end and a second housing end along a central longitudinal axis. The permanent magnet machine also includes a stator disposed within the machine housing, the stator having a stator core having an exterior surface extending between a first face and a second face along the central longitudinal axis, wherein the exterior surface defines a discontinuous region that is arranged to minimize points of contact between the inner surface and the exterior surface. The discontinuous region is at least partially defined by at least one of a first perturbation and a second perturbation that is circumferentially spaced apart from the first perturbation.

Abstract: Technical solutions are described for providing driver warning using steering systems. An example steering system includes a motor control system that sends a command to a motor. The steering system further includes a fault monitoring system that sets a fault indication flag by monitoring one or more components of the steering system. The steering system further includes a driver warning feedback system that generates a warning injection signal based on and in response to the fault indication flag being set. Further, the motor control system generates a driver feedback by modifying the command to the motor using the warning injection signal, and sending the modified command to the motor.
