Background. The relevance to study and synthesize the optimal rotor design is caused by the need for an integrated design approach that takes into account the multitasking and multi-criteria nature of modern electric motors. One of the striking examples of progress is the Xiaomi Super Motor series due to the fact that the rotor rotation speed reaches 21,000 rpm, which contributes to the rapid acceleration of the vehicle and lower energy consumption. The purpose of this study is to develop a mathematical model and conduct experimental studies to study the design of the Xiaomi Super Motor V6 electric motor.
Materials and methods. Numerical methods of modeling electromagnetic fields, general principles of the theory of modeling electric machines, as well as experimental studies on a laboratory sample have been used to solve the tasks set. The modeling has been carried out using the finite element method.
Results. The influence of the rotor design on the output characteristics of an electric motor has been analyzed. A simulation and experimental study of Xiaomi Super Motor V6 electric motor has been carried out. The dependences of the electromagnetic moment and output power on the angular velocity of rotation have been obtained with a limited supply voltage of 567 V.
Conclusions. The results obtained can be applied to further research of the topologies of rotary systems by scientific research and manufacturing companies specializing in the development of electric machines.
