[Abstract]:With the development of modern civil society, motor has already become one of the main production tools to enhance productivity and improve people's quality of life. The appearance of maglev motor has solved the problems of bearing wear during rotor rotation, which leads to the decrease of bearing life, mechanical vibration and noise. The hybrid maglev motor reduces the space size compared with the traditional maglev motor because of its permanent magnet rotor structure, which not only improves the efficiency of the motor conversion, but also reduces the loss of power amplifier. However, in order to further reduce the size of the motor and optimize the structure of the maglev motor, the stator structure of the hybrid maglev motor can only be started with the method of single coil winding, which is used to drive the rotation of the rotor shaft. It is also used to drive the suspension of the rotor shaft. In particular, three sets of independent distributed windings are used to control the suspension of the rotor in three directions. At the same time, the three sets of windings can work together to form a rotating magnetic field to drive the motor rotation, which can further reduce the size of the motor on the stator. In this paper, the structure design and radial control drive of hybrid maglev motor are studied. The structure design of hybrid maglev motor is based on the traditional motor design. The development of radial control drive of hybrid maglev motor mainly starts with control drive circuit and software program. The specific work includes the following parts: the structure and operation principle of hybrid maglev motor are introduced, the electromagnetic mechanism of hybrid maglev motor is analyzed, and the principle of virtual displacement is used. The radial suspension force equation of hybrid maglev motor is established. The structure design of hybrid maglev motor is mainly divided into radial suspension motor stator rotor structure parameter determination axial suspension motor stator rotor structure and electromagnet parameters. The magnetic field distribution of the main components and the relationship between the magnetic suspension force and displacement and other control parameters are obtained by using the Ansoft electromagnetic field finite element analysis software. Based on the structure design of hybrid maglev motor, the radial control drive hardware is designed, which is mainly divided into two parts: motor rotation drive hardware design based on SVPWM technology and suspension hardware design based on full-bridge power amplifier. Then the software control flow is briefly explained. The related experimental platform of hybrid maglev motor is built and the experimental results are basically in accordance with the scheduled requirements.
