[0003] The magnetic levitation motor in the prior art needs to be installed with a protective bearing. The magnetic bearing is first energized to float the rotor, so that the rotor does not contact the protective bearing. When the machine stops, the rotor directly falls on the protective bearing. Deep groove ball bearings), the cost is relatively high, and frequent maintenance and replacement are required. In addition, the motor rotor needs radial magnetic bearings and axial magnetic bearings to prevent the motor rotor from shifting, which makes the structure of the motor more complicated, so it needs further improvement

The invention relates to a magnetic-liquid mixed suspension type axial magnetic flux rotating motor which comprises a shell, a rotating shaft penetrating through the shell, a driving stator arranged between the shell and the rotating shaft, a driving rotor, an electromagnetic suspension module and a fluid suspension module, and the electromagnetic suspension module and the fluid suspension module are arranged in the shell and are arranged between the shell and the rotating shaft. The bearing capacity of the motor is improved in a magnetic-liquid mixed suspension mode, the maintenance period is prolonged, the rotor can suspend under the condition that a magnetic bearing is not powered on, meanwhile, a protection bearing and an axial magnetic bearing of a traditional magnetic suspension motor are omitted, the structure of the magnetic suspension motor is simplified, and in addition, the magnetic suspension motor is convenient to maintain. The hybrid suspension mode is adopted to achieve advantage complementation of the two suspension modes, the reliability of the system is improved, and the hybrid suspension system can be widely applied to the fields of air compression, energy storage and the like and has wide application and popularization value.
Description
technical field [0001] The invention relates to the technical field of electric motors, in particular to a magnetic-liquid mixed suspension type axial magnetic flux rotating electric machine. Background technique [0002] High-frequency and high-efficiency motors with high power, high speed, miniaturization and low energy consumption are an inevitable trend in the development of the motor field in the future. Reducing the energy consumption of the motor is one of the keys to achieve the efficient operation of the motor. The friction between the stator and the mover when the motor is running The loss limits the efficient operation of the motor. The application of the magnetic levitation technology to the motor can greatly reduce the friction loss between the stator and the mover and improve the operation efficiency of the motor. Magnetic levitation technology is to use magnetic force to overcome gravity to suspend objects and put them in a frictionless, non-contact suspension...
