1. A motor comprising:
a stator including a stator core, a plurality of stator windings, and a routing insulator provided at an axial end of the stator core to electrically insulate the stator core from the plurality of stator windings;
a rotor rotatably received within the stator and including a rotor shaft extending along a longitudinal axis and a plurality of permanent magnets; and
a plurality of stator terminals supported by the routing insulator and extending away from the stator, each stator terminal including a main body having a first portion mounted at or near an outer periphery of the routing insulator and a second portion extending angularly-inwardly from a first side of the first portion, a tang portion folded over the second portion of the main body and receiving a portion of a magnet wire therein to make an electrical connection with at least one of the stator windings, and a terminal pin projecting axially away from the stator core,
wherein the plurality of stator terminals is fully contained within an outer envelope of the stator defined by an outer circumferential surface of the stator core.
