摘要： A method and apparatus for forming a coreless armature winding for an electric machine, such as a motor, having two or more poles. A source of wire is revolved in a fixed orbit about a rotatable cylinder, the axis of this orbit being inclined with respect to the longitudinal axis of the cylinder. The wire is guided about first and second guide members positioned at opposite spaced apart locations on the surface of the cylinder. These guide members define the opposite ends of the coreless armature winding such that when the wire is wound thereabout, one complete turn is formed on the surface of the cylinder. The cylinder is rotated about its longitudinal axis in synchronism with the revolution of the wire, the cylinder being rotated by a predetermined angle corresponding to the pitch of the winding so that, as the wire continues to revolve, successive skewed turns are formed on the surface of the cylinder. The guide members are rotated as the cylinder rotates, and after a predetermined number of turns have been formed, the guide members are returned to their respective initial positions. Then, the foregoing operation is repeated until a complete armature has been formed. In one embodiment, the guide members are returned to their respective initial positions after each complete turn is formed. In accordance with another embodiment, the guide members are returned to their initial positions after a number of turns corresponding to a pole width have been formed.
