A pole piece assembly (28) for an electric motor (20) formed of stacked interlocked lamina (46) that define a first set of stacked lamina (50) and a second set of stacked lamina (52). Each of the lamina (46) of the first (50) and second (52) sets of stacked lamina include a hole (60) with the holes (60) being aligned with each other to define an internal cavity. A post (64) is disposed within the cavity with the post (64) having an outer surface (66) and a pair of bores (68) disposed therein. The pole piece assembly (28) is characterized by each of the lamina (46) of the second set of stacked lamina (52) further including a notch (74, 78) with the notch (74, 78) mating with the hole (60). The notches (74, 78) of the second set of stacked lamina (52) are aligned with each other to define a passageway into the internal cavity with the bore (68) of the post (64) being aligned with the passageway to expose the bore (68).
