Abstract
An electric machine including a stator, a rotor within the stator, and a shaft to which the rotor is mounted. The shaft extends through the stator. A first bearing and a second bearing support the shaft within the stator to allow the shaft and the rotor to rotate within the stator. The rotor is between the first bearing and the second bearing. A first magnetic core is at the shaft between the rotor and the first bearing. The first magnetic core is configured to suppress a bearing current flowing across the shaft, the first bearing, and the second bearing.
