The invention relates to an axial permanent
magnet spherical surface
magnetic levitation flywheel motor, belonging to the technical field of
magnetic levitation motors. The axial permanent
magnet spherical surface
magnetic levitation flywheel motor comprises a
flywheel, a rotor and a
stator. The flywheel and the rotor form an integral body, the
stator and the rotor are divided into an A phase anda B phase in an axial direction, and axial reverse magnetizing permanent magnets are respectively clamped between a rotor A-phase magnetic conducting ring and a rotor B-phase magnetic conducting ringand between a
stator A-phase magnetic conducting ring and a stator B-phase magnetic conducting ring; the rotor comprises a rotor A-phase spherical surface iron core, a rotor B-phase spherical surfaceiron core, a rotor permanent
magnet, the rotor A-phase magnetic conducting ring and the rotor B-phase magnetic conducting ring; the stator comprises a stator A-phase spherical surface iron core, a stator B-phase spherical surface iron core, a stator permanent magnet, the stator A-phase magnetic conducting ring, the stator B-phase magnetic conducting ring and a stator sleeve; each-phase stator spherical surface iron core is provided with a wide-tooth suspension poles, narrow-tooth torque poles and magnetic isolating bodies, and the suspension poles and the torque poles employ pole shoe structures and are respectively wound with suspension control coils and torque control coils. The axial permanent magnet spherical surface magnetic
levitation flywheel motor improves the global uniformity ofair gap magnetic density, achieves the shaftless support of the flywheel and inhibits the gyroscopic effect; meanwhile, the
system integration level, the operation efficiency and the reliability are improved, and the decoupling of the suspension
magnetic circuit and the torque
magnetic circuit is achieved.
