PCT No. PCT/JP98/00250 Sec. 371 Date Aug. 31, 1998 Sec. 102(e) Date Aug. 31, 1998 PCT Filed Jan. 21, 1998 PCT Pub. No. WO98/33262 PCT Pub. Date Jul. 30, 1998A rotary electric apparatus functions as either a generator or a motor and has a rotary shaft defining an axial direction and a stator disposed around an external periphery of the rotary shaft. The stator has coil assemblies including coils wound around core members extending parallel to the axial direction and equidistantly disposed about the rotary shaft. The core members have opposing first and second stator pole surfaces normal to the axial direction and disposed respectively in opposing first and second sides of the stator. A first monopole rotor is fixed on the rotary shaft adjacent the first side of the stator and has all N-polar magnetic pole surfaces normal to the axial direction, disposed diametrically opposed about the rotary shaft, and alignable opposite the first stator pole surfaces during rotation of the first monopole rotor. A second monopole rotor is fixed on the rotary shaft adjacent the second side of the stator and has all S-polar magnetic pole surfaces normal to the axial direction, disposed diametrically opposed about the rotary shaft, and alignable opposite the second stator pole surfaces during rotation of the second monopole rotor. The S-polar magnetic pole surfaces are aligned opposing the N-polar magnetic pole surfaces with the stator therebetween. The stator has twice the number of core members as each of the first and second rotors respectively have N-polar magnetic pole surfaces and S-polar magnetic pole surfaces.
