Claim:
1. An electric machine, comprising: a support structure; a circuit board secured to said support structure; a stator secured to said support structure; a rotor rotatably secured to said support structure, said rotor defining an axis of rotation thereof, said rotor defining a wall thereof, said rotor includes a rotor core and further comprising a magnet secured to said rotor core; and a sensor secured to said circuit board and adapted to cooperate with said magnet to sense the position of the rotor relative to that of said stator, wherein said magnet extends outwardly in a direction parallel to the axis of rotation of the rotor beyond the rotor core, wherein said sensor defines a sensor surface thereof, wherein said magnet defines a sensor cooperating surface thereof, and wherein the sensor surface of said sensor and the sensor cooperating surface of said magnet face each other with no other elements between each other, wherein the portion of said magnet extending beyond said rotor core defines opposed inner and outer magnet surfaces; and wherein one of the inner magnet surface and the outer magnet surface defines sensor cooperating surface of said magnet.
