Abstract
An electromechanical machine includes a stator fixed with respect to a housing structure and a rotor fixed with respect to a shaft. The shaft is rotatably supported by a pair of bearing assemblies maintained in the housing structure. A pair of coilheads extend from respective sides of the stator core axially external of the rotor. Shaft shields, preferably configured as tubular members, radially interpose the shaft and the respective coilhead. The shaft shields may be constructed of a magnetically permeable material to divert flux that would otherwise cut through the shaft. As a result, errant currents that could be induced in the shaft by such flux are desirably reduced.
