五相感应电动机缺相前后的电磁特性分析

ompared with the traditional three-phase induction motor, multiphase induction motor not only has the characteristics of high efficiency and high power density, but also has the advantages of small torque ripple and strong anti-interference. Therefore, it has been paid great attention in the application of electric ship propulsion, aircraft drive, locomotive traction and high-power industry. In this paper, a 15kw five-phase induction motor is taken as the research object. Based on Maxwell electromagnetic field theory, the two-dimensional electromagnetic transient field model of five-phase induction motor is established by using finite element simulation software, and solving the problem of the magnetic density, torque and electromagnetic loss of the motor under different working conditions.
