Abstract

A Brushless Direct-Current (BLDC) motor is provided for a power tool, including a stator comprising a set of coils, a rotor configured to rotate with respect to the stator, power supply lines, terminals secured to the stator outer surface of the stator, and a Hall circuit board. The terminals extend axially on the outer surface of the stator. A radial member is oriented radially adjacent a second side of stator proximate an axial end of the of coils, the radial member including a through-hole through which the rotor shaft extends, and discrete conductive routings electrically coupled to the coils and making electric contact with the coils at at least three distinct contact points to electrically connect the coils in a delta configuration.
