Abstract

The wind power industry is developing rapidly. In order to reduce costs and enhance the competitiveness of enterprises, wind power generation equipment is developing towards high power, high performance and high reliability. At present, the main wind turbines generally adopt the transmission form of single rotor with mechanical wind power gearbox, which can not meet the needs of efficient utilization of wind energy and low transmission failure rate of wind turbines. In view of the above problems, this paper proposes a new transmission mode of two-stage coaxial magnetic gear with double-rotor, compared with mechanical gears, the two-stage coaxial magnetic gear can achieve non-contact and large transmission ratio transmission, and has the advantages of low vibration, low noise, no lubrication and low maintenance costs. Based on the differential two-stage coaxial magnetic gear structure and its working principle, the finite element method is used to simulate the electromagnetic performance of the two-stage coaxial magnetic gear. Futhermore, the electromagnetic performance of the two stages of the proposed magnetic gear are compared. The results show that there is a significant difference in torque ripple between the first and second stages of the two-stage coaxial magnetic gear. The torque ripple of the second stage is more dramatic than that of the first stage. The torque ripple amplietude of the inner rotor of the second stage is 41.68% larger than that of the second stage. The torque ripple amplietude of the outer rotor of the first stage is 9.6‰ larger than that of the second stage. Improvements were made to reduce the large torque ripple in the second stage, and the results showed that the torque ripple of the inner rotor was reduced by 48.27% after the improvements.
