  • Axial split-phase bearingless flywheel motor of three phases and four degrees of freedom
    Patent number: 11128196
    Abstract: An axial split-phase bearingless flywheel motor includes a stator, a stator sleeve, a rotor, a rotor sleeve, and a flywheel. The stator and the rotor are axially divided into phases A, B and C. An axially magnetized permanent magnet is provided between every adjacent phases. Twelve rotor poles are provided at equal intervals on an inner side of the rotor core in each of the phases A, B, and C. The rotor poles in the phases A, B and C are staggered in sequence along a circumference by ? of a rotor pole pitch. Eight torque poles in a shape of narrow teeth and four suspension poles in a shape of wide teeth are provided on the stator core in both the phases A and C, and twelve torque poles of a uniform width are provided on the stator core in the phase B.
