摘要:
A cylindrical linear motor, an electromagnetic suspension, and a vehicle using the same, which can generate a large thrust and reduce torque pulsations and cogging torque. The cylindrical linear motor comprises a stator and a slider disposed with a gap left relative to the stator and being linearly movable relative to the stator. The stator comprises a stator core having stator salient poles, and 3-phase stator windings inserted in slots formed in the stator core. The slider comprises a plurality of permanent magnets fixed to a slider core. The motor satisfies τp:τs=9:9±1 where τs is a pitch of the stator salient poles and τp is a pitch of the permanent magnets.
