[Class 35] [Also in Group XXXVI] The leakage reactance of the magnetic circuits of rotary machines used in a "microsystem " is increased by the provision, of very broad notches 2, 5, for containing the windings and damping means, communicating with slots 3, 7. The portions 6 between the notches 5 are of small cross-section and easily become saturated.
