Abstract
A brushless direct-current (BLDC) motor for a power tool includes a rotor assembly; a stator assembly including a stator having stator teeth forming slots therebetween and stator windings wound around the stator teeth; stator terminals extending substantially parallel to the longitudinal axis from the stator assembly and being substantially aligned with centerlines of the slots of the stator assembly; and a circuit board mounted on the stator terminals adjacent the stator assembly. The circuit board includes conductive traces facilitating a one of a delta or a series connection between the stator windings. An end insulator is provided at an axial end of the stator to electrically insulate the stator from the stator windings, the end insulator including support members to support the stator terminals relative to the stator assembly. The circuit board is mounted and fastened to the support members.
