  • Patent number: 7242122
    Abstract: An electric motor has a dimensional arrangement of both the rotor and stator even at high level of torques that eliminates a flip-flop effect, which is typical for conventional step motors. Stator segments (3), on which coils (4) are placed, making up the poles of the motor, are compensated and are neutral from the point of view of forces FFe. The arrangement satisfies simultaneously a number of interrelationships including the number and design engineering arrangement of the permanent magnets of the rotor (2), the number and design engineering arrangement of the stator segments (3) made from soft magnetic material, the number of the motor phases, and the number and position of stator coils (4) that make up the poles of the motor installed on every segment (3) depending on the number of motor phases.
