Abstract
A coil form for winding stator wire includes front and back coil forms which are designed to overcome the drawbacks of the known coil forms. The front coil form is adjustable between a first open position in which coils may be formed in a first series of sizes and a second closed position in which coils are formed in a second series of sizes. The adjustable front coil form allows tooling to be changed between even and odd winding form configurations without delays due to required set up time. The back coil winding form includes a tapered back surface which prevents coils from moving forward or unwinding before they are captured in a coil-receiving fork. This prevents coils from being received in an improper slot in the fork and allows the manufacture of a high quality product.
