| description | Abstract In this paper, a high speed slotted solid-rotor induction motor (SSRIM) with rated power of 15 kW and rated speed of 120krpm is studied, and its electromagnetic performance and rotor mechanical structure are optimized. First, according to the empirical formula of motor design, the volume size of the motor is determined. Then, by constructing a two-dimensional finite element model, the slot matching scheme and coil pitch are optimized, and the influence of different slot matching scheme and coil pitch on the output torque and harmonics of the motor is compared. Then, the influence of rotor slot size on electromagnetic and mechanical properties of the motor is described in detail. Finally, a finite element model is constructed to verify the mechanical strength of the rotor, and the influence of temperature on the deformation and stress of the rotor is explored. Through the analysis, it is found that the slot matching scheme has a great influence on the torque ripple of the motor, and the torque ripple can be reduced by selecting the slot matching scheme reasonably. Secondly, the size of the rotor slot has a great impact on the electromagnetic and mechanical properties of the motor, and it is necessary to comprehensively consider and jointly optimize its size. |
