Stereo-cultivation of mushroom is performed under the mango trees, management is more convenient, during fruiting, the space under the mango trees is filled with mushrooms, the scene is spectacular, and the beautiful scenery line is added to sightseeing tour.

Rotor for permanent magnet synchronous motor and permanent magnet synchronous motor
PendingCN114744790ASmall torqueLow noise and vibrationSynchronous machine detailsMagnetic circuit rotating partsElectric machinePermanent magnet synchronous motor
The invention discloses a rotor for a permanent magnet synchronous motor and the permanent magnet synchronous motor. The rotor for the permanent magnet synchronous motor comprises a rotor iron core, the rotor iron core is provided with a plurality of magnetic pole grooves extending along the axial direction, and permanent magnets extending along the axis are arranged in the magnetic pole grooves; the outer surface of the rotor core is provided with a plurality of auxiliary grooves, and the auxiliary grooves and the magnetic pole grooves are mutually independent; and the auxiliary groove has a deviation angle. By adopting the scheme, the cogging torque of the motor can be reduced, the air gap flux density waveform can be corrected, the sine degree of the back electromotive force waveform can be improved, noise vibration caused by defects of the motor body can be reduced, and the electromagnetic performance of the motor can be improved. According to the scheme, the increase of assembly procedures caused by a traditional rotor skewed pole can be avoided, meanwhile, the structural strength of the motor rotor punching sheet is not influenced, more effects of selecting the position and the axial shape of the auxiliary groove are not influenced, and in some specific positions, the noise and vibration performance of the motor can be improved, and the output of the motor is not reduced or even improved.
