Claims
- 1. An electric motor which comprises a rotor having a shaft and a U-shaped stator having two shanks, each shank having a free end, said motor also including induction coils disposed around each of said shanks, each of said shanks being formed to define pole shoes between the free ends of each of said shanks and said induction coil disposed on that shank, said U-shaped stator having the major portion thereof configured so that an imaginary central plane extends through all of said stator except the free ends of said shanks, each of said shanks in the area between said pole shoes and said coils being bent with respect to said central plane in such a manner that said shaft encloses with said central plane an angle which is less than 90.degree..

- 12. An electric motor as claimed in claim 1 wherein each of said shanks has a second axially spaced induction coil mounted thereon.
- 13. An electric motor which comprises a rotor having a shaft and a U-shaped stator having two shanks, each shank having a free end, said motor also including induction coils disposed around each of said shanks, each of said shanks being formed to define pole shoes between the free ends of each of said shanks and said induction coil disposed on that shank, said U-shaped stator having the major portion thereof configured so that an imaginary central plane extends through all of said stator except the free ends of said shanks, each of said shanks in the area between said pole shoes and said coils being bent with respect to said central plane in such a manner that said shaft encloses with said central plane an angle which is more than 90.degree..
- 14. An electric motor as claimed in claim 13, characterized in that a hinge is provided in each of said shank and in said central plane of said stator.
- 15. An electric motor as claimed in claim 13, wherein said shanks each include projections for cooperation with recesses in axially adjacent portions of respective shanks.
- 16. An electric motor as claimed in claim 13, wherein said shanks have dimensions parallel to said central plane which is much larger than a dimension at right angles to said central plane.
- 17. An electric motor as claimed in claim 15, wherein said shanks have a larger dimension perpendicular to said central plane than in the direction parallel to said central plane.
- 18. An electric motor as claimed in claim 16, wherein the dimension of said shanks parallel to said central plane is in the order of between 7 and 15 units and the dimension of said shanks perpendicular to said central plane is in the order of magnitude of 1 to 7 units.
- 19. An electric motor as claimed in claim 16, wherein the dimension of said shanks perpendicular to said central plane is in the order of between 7 and 15 units and the dimension of said shanks parallel to said central plane is in the order of magnitude of 1 to 7 units.
- 20. An electric motor as claimed in claim 18, wherein the dimension of each of said shanks parallel to said central plane is in the order of magnitude of 12 units and the dimension of said shanks perpendicular to said central plane is in the order of magnitude of 5 units.
