摘要：
In order to analyze the influence of rotor field harmonics on the electromagnetic torque, and accurately simulate the motor dynamic operating conditions, a double closed-loop nonlinear Simulink model was established based on the deduction of mathematical model accounting for rotor magnetic field harmonics. The model was also compared with the open-loop model. The results show that the 6K(K∈N) components of electromagnetic torque and rotational speed harmonics except 6K come from the rotor magnetic field harmonics. Finally, high-order torque test was conducted for the target motor. The result shows that the established double closed-loop model is accurate and can help to analyze the dynamic torque characteristics. © 2015, Central South University of Technology.
