1. 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;
a replaceable winding located on the pole portion comprising:
a body having a longitudinal axis, the body comprising opposing surfaces along the longitudinal axis;
an aperture through the body, between the opposing surfaces, the aperture having generally parallel internal sides about perpendicular to the opposing surfaces of the body, the aperture configured to removably receive a pole portion of the electromagnetic machine;
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; and
at least one removable retention mechanism to removably retain the replaceable winding at the pole portion, the at least one removable retention mechanism comprising at least one ferromagnetic retainer removably attached to an external surface of the pole portion extending at least partially across an outward opposing surface of the replaceable winding.
