Embodiment Construction
[0034] figure 1 The magnetic field line direction of the magnetic field between the rotor magnet 2a of the rotor 2 and the stator 4 of the brushless electric motor 6 is schematically shown. The rotor is supported in a manner capable of rotating around the motor axis M extending in the axial direction A. Here, for the purpose of better visibility of the magnetic field line direction, it is only partially shown. therefore, figure 1 Only half of the rotor 2 and the stator 4 are shown, wherein the unshown half of the rotor 2 and the stator 4 are mirror-symmetrical with respect to the plane E, the motor axis M extends through the plane, and the plane is perpendicular to the drawing Oriented flat.
[0035] The stator 4 has an annular stator yoke 8 from which stator teeth 10 extend away from the motor axis M toward the rotor 2 in a star-shaped manner, that is, in a radial direction R oriented perpendicular to the axial direction A. Therefore, the rotor 2 is arranged outside the stato...
