Abstract: Non-contact coil form measurement and control apparatus for measuring the spread of a coil forms includes a bar code scanner for determining the relative positions of the coil forms. More particularly, the bar code scanner is mounted to the winding machine at a location which enables the scanner to scan both forms. The scanner may be coupled to the winding machine controller which controls operation of the winding machine. A target, such as a bar code, is positioned on each coil form. In operation, when a particular stator configuration is to be fabricated, the operator enters the stator configuration identification into the winding machine controller. The scanner then scans the bar codes located on the forms to determine the coil form separation. In the event that the coil forms are incorrectly set, the controller interface informs the operator of this condition and instructs the operator to set the coil form spread.

Abstract: An apparatus and method for testing a coating on a conductor, such as a dielectric coating on a wire. A high voltage source is coupled to the conductor and the coating through a primary winding of a transformer. Faults in the coating will result in a change in current in the primary winding thus inducing current in a secondary winding of the transformer. Current in the secondary winding is detected by a sensor and fault data can be compiled by known data acquisition devices.
