Patent ID: 7723888

Claim:
A synchronous electromechanical transformer, which has a radial, axial or linear design, comprises two stators and one rotor, which is disposed between the two stators and can be displaced relative thereto, the rotor comprising approximately uniformly distributed, alternately oriented magnetic poles, the stator comprising poles with or without magnetically permeable pole cores and one or more magnetically permeable parts by which the magnetic flux between adjoining poles is closed on the side that does not abut the magnetic gap, characterized in that the stator comprises an identical number of identically disposed electromagnetic poles of each of at least two electrical phases, which are provided in related groups of at least two electromagnetic poles, wherein all electromagnetic poles of the individual group pertain to the same electrical phase and the adjoining electromagnetic poles of the same group are electrically offset by 180°, the number of rotor poles that abut the magnetic gap with the individual stator (M) differing from the number of electromagnetic poles of the stator (E) by the product between the number of stator groups whose electromagnetic poles pertain to the same electrical phase (G) and a natural number (n) that is not a multiple of the number of electrical phases (F), M=E±nG, wherein the adjoining electromagnetic poles that pertain to different stator groups are electrically offset by 180°+sgn(M−E) (180°/F)n, the natural number n preferably being equal to one and the number of stator groups of the individual stator whose electromagnetic poles pertain to the same electrical phase (G) is preferably equal to one or two, wherein the number of rotor poles that abut the magnetic gap with the individual stator being the same in both stators and both stators have the same number of poles and pole distribution, the winding of an individual phase comprising one or more partial windings connected in parallel, wherein every partial winding comprises the same number of electromagnetic poles in both stators and all electromagnetic poles of the individual stator group pertain to the same partial winding, and wherein the stators are disposed in relation to the magnetic poles of the rotor such that the effects of the two stators are added.
