摘要
A brushless synchronous machine is energized by permanent magnets with a stator and a rotor. The rotor is supported within the stator to allow rotation. The rotor has a plurality of cutouts into which permanent magnets are embedded. An air gap is provided between the stator and the rotor. The outer contour of the rotors is formed such that the electromagnetic force induced by the individual stator tooth winding has a trapezoidal characteristic. The maximum value of the electromagnetic force is present uninterrupted in an electrical angle range of 30° to 90°.
