Abstract
A housing supports a hollow shaft for both axial and rotary movement and also supports a drive input rotor for rotation on an axis perpendicular to the axis of the hollow shaft. The rotor carries an eccentrically located planetary gear which engages a surrounding stationary ring gear, and the planetary gear carries an eccentric crank shaft. A crank arm connects the crank shaft to a rotary coupling mounted on the hollow shaft, and an intermediate portion of the crank arm carries a rack which engages gear teeth on the hollow shaft. The rotor is provided with means for counter-balancing the moving components to provide for high speed winding of wire coils within a motor stator.
