Patent attributes
A power tool includes a housing and an electric motor. The electric motor includes a rotor assembly including a rotor shaft and a stator assembly including a plurality of stator segments. Each stator segment includes a core, an insulator at least partially covering the core, and a coil winding. The insulator includes a mounting portion. The electric motor also includes a printed circuit board assembly configured to direct electric current to each coil winding, and a bus bar assembly attached to at least one of the mounting portions and configured to electrically connect the coil windings to the printed circuit board assembly. The bus bar assembly includes a molded body and a plurality of conductors. The bus bar assembly defines a bearing pocket. The electric motor further includes rotor bearing that is received into the bearing pocket and that supports the rotor shaft for rotation relative to the stator assembly.
