Abstract
An electric machine includes a plurality of permanent magnets and a plurality of conductors. The plurality of permanent magnets are arranged radially around a rotation axis of the electric machine and spaced apart from the rotation axis of the electric machine. At least one of the plurality of magnets has a shape in a plane of rotation intersected by the rotation axis. The plurality of conductors are arranged relative to the plurality of magnets and spaced apart from each other circumferentially around the rotation axis of the electric machine. At least one of the plurality of conductors includes a trace having a polygon shape different than the shape of the at least one of the plurality of magnets.
