Abstract (en)

[origin: WO2010133796A1] The present invention relates to an electrodynamic Vernier machine with magnets, including a stator and a rotor, wherein: the stator includes teeth separated by notches opening into the air gap, said teeth defining a periodic pattern having a substantially constant pitch Ps; the rotor includes pads having an average width Lp and separated by notches opening into the air gap, said pads defining a periodic pattern having a substantially constant pitch Pr, Pr being different from Ps; said rotor includes magnets arranged in said notches, all the magnets having the same magnetic pole on the air gap side, characterized in that the average width Lp of the rotor pads is lower than 0.5 times the pitch Pr of said pads, said average width Lp being calculated over the height of the pad.
