Abstract:
A 2 000 r / min,12. 5 kW permanent magnet servo motor was taken as the research object,ac-cording to the actual structure and control parameters of the motor,it is established two kinds of control strategy of the permanent magnet servo motor were established for two-dimensional transient finite element field-circuit coupled model. Then using a two-dimensional transient sinusoidal control strategy field circuit coupled finite element model was calculated by comparison with the experimental results and verifying the accuracy of the calculation method. Detailed study of the effects of carrier ratio of stator iron losses and ro-tor eddy current losses of the sheath with square wave and sine wave control was conducted. Finally,based on steady-state heat transfer theory,a permanent magnet servo motor domain-dimensional finite element model of temperature field was established,respectively with the above two kinds of control model of dif-ferent carrier ratios,two motor temperature fields were calculated,and the motor of the components were studied temperature variation. The research is to provide a reference for selecting permanent magnet servo motor control scheme and control parameters.
