Abstract
The present invention provides an improved single-layer coil 10 for a rotating or linear electrical machine. The coil 10 has a first endwinding 12 that is substantially parallel to a longitudinal axis LA of the coil and a second endwinding 14 that is bent away from, or towards, the longitudinal axis. The coil 10 therefore has differently shaped endwindings with one end 12 being ‘straight’ and the other end 14 being ‘bent’.
