Claim 14:
15. A coil support for preformed flat coils of a stator of an electric rotary motor, the coil support comprising:
an annular supporting structure; and
a plurality of columns extending upwardly from the supporting structure and being spaced apart from each other to form a corresponding plurality of coil receiving portions configured to hold the preformed flat coils in place before a potting operation,
wherein each of the coil receiving portions is configured to support a lower part of one of the preformed flat coils, and
wherein the coil support further comprises a first and second plurality of insulating sheet supports extending radially and outwardly from the annular supporting structure, wherein the first plurality of insulating sheet supports extend further in the radial direction than the second plurality of insulating sheet supports, and wherein each of the insulating sheet supports of the first plurality of insulating sheet supports is located between two insulating sheet supports of the second plurality of insulating sheet supports such that a circulate insulating sheet has a corrugated shape in a mounted state on the first and second plurality of insulating sheet supports.
