Abstract: A permanent magnet machine includes a machine housing and a stator disposed within the machine housing. The machine housing has an inner surface that extends between a first housing end and a second housing end along a central longitudinal axis. The stator has a stator core having an exterior surface and an interior surface, each extending between a first face and a second face along the central longitudinal axis. The stator core defines a plurality of openings that extend from the first face towards the second face.

Abstract: A permanent magnet machine includes a machine housing and a stator. The machine housing has an inner surface. The stator is disposed within the machine housing. The stator has a stator core having an exterior surface. At least one of the inner surface and the exterior surface defines a discontinuous region that is arranged to minimize points of contact between the inner surface and the exterior surface.

Abstract: An electric motor assembly comprising a stator having a plurality of stator lamination sheets. Each of the stator lamination sheets includes an annular body and a plurality of stator teeth extending radially inwardly from the annular body to an opening. A rotor is located in the opening. Each of the stator teeth defining a pocket with a dampening element located in the pocket. The dampening element comprises a material that is viscoelastic. The pocket and dampening element are located in a location of the stator tooth that has less magnetic flux than an adjacent area of the stator tooth.

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.
