Properties of brushless DC machine induced by permanent magnets applied to a traction drive

The paper presents a mathematical model of brushless DC machine induced by permanent magnets. Its construction uses the classical model of permanent magnet synchronous machine and induced model of power inverter using the serraphil form. The results of the computer simulation were presented for such states: startup, work under active constant load and the behavior of the machine in terms of exponential and stepping change of the power inverter´s control angle.
