Brushless motor in power tool

An electric motor comprising:

• a rotor assembly including a rotor shaft;
• a stator assembly including a plurality of stator segments, each stator segment including a core, an insulator at least partially covering the core, and a coil winding wound from a magnet wire, the insulator including an axial retainer extending longitudinally thereof, wherein the plurality of stator segments includes a first stator segment and a second stator segment adjacent the first stator segment in a circumferential direction;
• an outer tubular housing disposed around and in contact with the plurality of stator segments;
• a printed circuit board (PCB) assembly configured to direct electric current to each coil winding, the PCB assembly being mounted on the axial retainers of the plurality of stator segments;
• and
• an end cap supporting the PCB assembly, wherein the end cap includes a center bearing pocket that supports a bearing of the rotor shaft.
