Claim 8:
9. An electromagnetic machine comprising:
a ferromagnetic body extending along a longitudinal axis, the ferromagnetic body comprising: a back-iron portion; and a pole portion extending from the back-iron portion, the pole portion having parallel external sides; and
a replaceable winding located on the pole portion comprising: a body along the longitudinal axis, the body comprising opposing surfaces along the longitudinal axis; an aperture through the body, between the opposing surfaces, along the longitudinal axis, the aperture having parallel internal sides about perpendicular to the opposing surfaces of the body, the aperture configured to removably receive the pole portion such that the parallel external sides of the pole portion and the parallel internal sides of the aperture are adjacent when the replaceable winding is on the pole portion; electrical conductors wound about the aperture in the body; and electrical connectors at one or more external sides of the body, the electrical connectors connected to the electrical conductors;
at least one removable retention mechanism to removably retain the replaceable winding at the pole portion; and
at least one plate removably retained at a ledge of the back-iron portion adjacent the pole portion, the replaceable winding located on the at least one plate, and the at least one removable retention mechanism comprising one or more straps around the replaceable winding and the at least one plate.
