The present invention relates to an electrical multipole motor/generator or electrical machine with axial magnetic flux, wherein the machine has a numbe r of stator pole cores being larger than the number of rotor pole shoes. Thus, a motor/generator or electrical machine is provided in which the machine comprises a rotor secured to a shaft with an axis of rotation, where the rot or comprises magnets or means for producing a magnetic field and a number set t o N of pole shoes. The machine further comprises a first stator with air gaps formed between the rotor and the first stator, where the first stator comprises a number set to M of separate pole cores or pole legs having corresponding separate coils or set of windings wound on and surrounding sai d pole cores or pole legs, wherein N and M are larger than one and M is larger than N. N may be an equal number, and M may be equal to 2N, or M may be equa l to 3N, or M may be equal to 4N. According to an embodiment of the invention, the electrical machine may further comprise a second stator with air gaps formed between the rotor and the second stator, where the second stator comprises a number set to P of separate pole cores having corresponding separate coils or set of windings wound on and surrounding said pole cores, wherein P is larger than one. P may be larger than N, and P may be equal to 2N, or P may be equal to 3N, or P may be equal to 4N. Thus, according to an embodiment of the invention P may be equal to M. |
