Designing polyester magnet wires to service requirements

Designs of magnet wire should be based upon customers' needs and the unique properties of particular polymers should be used to appropriate advantage. In order to be able to design wires which fill the customer's needs, the wire engineer must understand these needs and also be able to translate these requirements into meaningful tests which correlate with actual performance. Three tests which do this are the arbor winding test, the revised heat shock test and the core-coil burn-out test.
