摘要： Aircraft and aircraft electric motors include a rotor assembly comprising a plurality of magnets (214) arranged on a magnet support, an output shaft operably coupled to the rotor assembly, and a stator (210) comprising a support structure and at least one winding wrapped about a plurality of stator teeth, the stator configured to generate an electromagnetic field to cause rotation of the rotor assembly. The magnets are configured in sets arranged circumferentially about the rotor assembly, with each set having a cut-out notch at opposite ends of each set in the circumferential direction and wherein the cut-out notch is at least partially formed in an in-pole magnetization magnet having a radial orientation magnetization.
