ABSTRACT

A direct drive robot motor may be used for the arms, legs, eyes and fingers of
a robot. The motor comprises a rotor, having a permanent magnet, and a tubular
arm portion, which is integral with the rotor and extends outwardly through a
slot in a stator body. The stator body is wound with an aluminum coil and has
a tubular extension to link it with the arm of another direct drive motor.
