Abstract
An electric motor has features for preventing the bearings from rotating. The motor has a stator mounted in a housing. A rotor is rotated within the stator. The rotor is divided into rotor sections, with bearings spaced between. Each bearing has an outer portion that contains outwardly biased pins. The pins engage slot gaps formed in the stator laminations.
