ABSTRACT:
A motor assembly for driving a working element of a power tool which is provided includes first and second clamshell housing members connectable to define an interior space for the power tool motor and a longitudinal axis extending through the interior space. An armature includes a core and a rotatable shaft for driving a working element of the tool. The armature is mountable in the interior space with the rotatable shaft aligned along the longitudinal axis. A cylindrical stator yoke is mountable in the interior space about the longitudinal axis to encircle the armature. Top and bottom bearings are mounted on corresponding ends of the armature shaft. Alignment and support members on the first and second housing members are provided with the alignment and support members capturing and fixing the yoke and top and bottom bearings in the interior space in alignment about the longitudinal axis when the clamshell housing members are connected to each other.
