High frequency model of permanent magnet synchronous motor is developed considering all the turns in the winding. Finite element analysis is used for accurate determination of winding parameters such as resistance, inductance and capacitance at high frequency of operation. From these calculated parameters lumped model is built for high frequency winding branch. Matrix reduction technique is applied to reduce the order of model. This lumped parameter model for high frequency branch is connected in parallel with low frequency phase variable model to form high frequency phase variable motor model. This model is then used in the simulation of integrated motor drive consisting of inverter, cable and motor to predict the overvoltage phenomena at the terminal of motor and internal voltage transient response. Also this model is used in speed control application to show its performance behavior. © 2005 IEEE.
