Abstract
An electric motor and winding method that improves its characteristics of torque and speed. An improved electric motor that provides higher power density and safety features by a novel winding architecture. Since the new winding architecture does not affect the measures, design or materials of the electric motor there is no need for any special manufacturing process or extra cost. Therefore the improved electric motors are smaller, lighter and cheaper than the same power size conventional electric motors as in other prior arts. The improved electric motor provides redundancy features against failure.

1-14. (canceled)
An electric motor, said electric motor comprising:
- A rotor,
- a stator comprising a stator core with a plurality of salient stator poles arranged in groups as number of motor electrical phases, the stator poles group having an equal number of poles, each group of stator poles comprising at least one stator pole, the electrical phase being split into groups, each electrical phase having at least one electrical phase group, each electrical phase group being formed by a plurality of series of electric coils, each series of coils comprising at least one electric coil, each series of coils in the electrical phase group having equal number of turns, wherein the total number of series of coils in each electrical phase group is divided in two subgroups of equal number of series of coils, each subgroup comprising at least two series of coils and each coil comprising at least one turn, wherein the series of coils in each electrical phase group are all connected on one end creating a common connection (300), and the other end of each series of coils in a group having its own termination, giving a plurality of exposed terminations (130, 131, 132, 133).
