Abstract: A system has an electric motor having a stator and a rotor. The rotor rotates with a shaft and the shaft drives a fluid rotor. A control senses a fault condition on the electric motor. The control actuates a speed reduction feature when a fault is detected to bring rotation of the motor rotor and the fluid rotor to a stop more rapidly than if the speed reduction feature had not been actuated.

Abstract: A laminated stator for a motor includes a first plurality of stator laminations with a first electrical conductivity and a first thermal conductivity, and a second plurality of stator laminations with a second electrical conductivity and a second thermal conductivity, wherein the second electrical conductivity is lower than the first electrical conductivity, the second thermal conductivity is higher than the first thermal conductivity, and the second plurality of stator laminations are disposed throughout the first plurality of stator laminations.

Abstract: An insulating phase separator is used in an electric machine to separate phase windings in a stator assembly. The insulating phase separator includes first and second endturn portions and first and second leg portions. The first and second endturn portions each have a curved outer surface and a tabbed portion located opposite the curved outer surface. The first and second leg portions extend between the first and second endturn portions and are integral with the first and second endturn portions.
