Abstract

An electric motor stator including a yoke having a plurality of yoke laminations. A body portion is formed as part of each of the plurality of yoke laminations. A first tooth is continuous with the body portion and is formed as part of at least a portion of the plurality of yoke laminations. The first tooth defines a first tooth profile. A first tooth attachment portion is formed as part of the plurality of yoke laminations. A second tooth includes a plurality of tooth laminations. Each tooth lamination of the second tooth includes a second tooth attachment portion and defines a second tooth profile that differs from the first tooth profile. The second tooth attachment portion is engaged with the first tooth attachment portion.
