Description

TECHNICAL FIELD

[0001] The utility model relates to motor rotor technical field, concretely is a kind of axial flux disc type motor rotor structure. BACKGROUND

[0002] The working principle of axial flux disc type motor is similar to traditional motor, and is based on electromagnetic induction principle. When electric current passes through electromagnetic coil, magnetic field is generated, and the magnetic field between stator and rotor interacts, thereby generating electromotive force on rotor, driving rotor to rotate. The magnetic flux path of axial flux disc type motor is different from ordinary radial motor. The air gap is planar, and the direction of air gap magnetic field is parallel to the direction of motor axis. Due to the large diameter of rotor, axial flux disc type motor can obtain higher torque output under the premise of providing the same permanent magnet material and copper wire material. Usually, the torque density is improved by more than 30% compared with traditional radial flux motor.

[0003] In the prior art, the traditional axial flux disc type motor rotor includes a rotating shaft, and the diameter of the rotating shaft is usually fixed. If the appropriate bearing type and size are not accurately selected, or the load, rotating speed and temperature during actual operation are not considered, the bearing inner diameter and the rotating shaft diameter may not be matched. When the bearing inner diameter and the rotating shaft diameter are not matched, vibration may be generated in the running process of the bearing. The vibration not only reduces the running stability of the motor, but also generates additional noise. In the context of motor maintenance or emergency repair, the staff may need to quickly replace the bearing. If the diameter of the replacement bearing does not match the diameter of the rotating shaft, the staff needs to spend additional time to check the size of the bearing and the rotating shaft, find the appropriate replacement part, and perform necessary debugging work, which further prolongs the downtime.
