Abstract

The interior permanent magnet motor is the central component of modern high performance hybrid electric vehicles. During the vehicle's normal operation, demagnetization can occur in the magnets due to temperature rise and high current loading, which could change the IPM's electrical and mechanical characteristic and the overall system performance significantly. To study these effects on the system level, in this paper, we propose a reduced order motor model based on FEA solution that takes into account the permanent magnet's temperature dependency, current loading and nonlinear saturation effects. The proposed model runs at circuit simulation speed which is suitable for system level simulation and while having the accuracy of FEA. Using this model, we are able to quantify the current consumption during a standard drive cycle simulation due to temperature and current loading variations.
