Abstract
In a motor assembly, a rotor and a trigger wheel are each secured to a first race of a four-point contact ball bearing. The circumferential position of the rotor and trigger wheel are each fixed with respect to the first bearing, and therefore with respect to one another. A resolver sensor is bolted to a housing. A second race is mounted at a fixed axial position relative to the housing, thereby locating the trigger wheel with respect to the resolver sensor. In some embodiments, the first race may be an inner race and the second race an outer race. In other embodiments, the first race may be an outer race and the second race an inner race.
