N2 - Nowadays permanent magnet synchronous machines (PSM) are used more and more in different drive applications due to their high efficiency characteristics. Moreover, the multiphase machines have a promising future owing to higher fault tolerance and small torque ripple. In this work, the combination of analytical calculations and finite element analysis is used for thermal behavior estimation of multiphase PSM in faulty condition. The main purpose of work is to analyze how the coefficients of convection and the temperature dependent winding resistance influence the temperature distribution in the machine. This paper provides also the comparison of the temperature distribution not only during normal operation, but also after occurrence of faults, mainly open phase faults. These results can be used further for a fault tolerance assessment and improvement of multiphase electrical machines.
