Abstract
A direct-current motor-generator comprises at least one stationary magnetic circuit including a permanent magnet and forming an air gap of substantially cylindrical shape, and a generally cup shaped rotor bearing a motor winding and a generator winding. The arrangement of the at least one magnetic circuit and the windings is such that the magnetic flux passing through the one of the said windings is separated in space from the flux passing through the other of the said windings.
