Abstract

Modular Planar windings that use non-overlapping coils are simple and inexpensive to wind and robust in operation. The coils may be pre-formed before slot insertion and therefore yield a high slot packing factor. However, high amplitude unwanted backward going fields are produced by all forms of the windings which reduce their performance when used in induction machines. This paper develops a number of single-sided machines using multi layered modular coils in which the layers are offset to cancel the unwanted fields. Use is made in these arrangements of short concentric winding groups. A comparison between the performance of a machine using an example of the new windings and a production linear machine is drawn using both finite element analysis and practical variable frequency standstill tests.
