The invention provides means of limiting maximum current conducted through windings of an electric machine having a rotor and a stator. By encouraging an appropriate leakage flux around a winding, a leak impedance can be achieved which may be used, according to the invention, to limit the maximum current in the winding as a matter of machine design.
1. A method of providing a current-limited machine, the method comprising the steps of:selecting a rotor design; selecting at least one magnetic material to comprise a stator; defining a stator geometry, including the steps of: defining a stator core; defining a plurality of spaced-apart teeth adapted to receive at least one winding therebetween; defining at least one primary magnetic flux path for guiding magnetic flux from an adjacent moving magnetic rotor along at least some teeth, through the core, past the at least one winding and back to the rotor ...
