Abstract

An electric motor, power tool using the electric motor, and method of making the electric motor includes making a stator by separately forming pole pieces (314), return path pieces (306) and field coils (304). The field coils are placed over necks of the pole path pieces and the return path pieces are affixed to the pole pieces. An armature having an outside diameter of at least 0.625 the outside diameter of the stator is placed in the stator. In an aspect, the field coils are formed so that they extend beyond pole tips of the pole pieces.
