A three-phase motor rated 1 kW, 500 Vdc, 3000 rpm is fed by a six step voltage inverter. The inverter is a MOSFET bridge of the SimPowerSystems™ library. A speed regulator is used to control the DC bus voltage. The inverter gates signals are produced by decoding the Hall effect signlas of the motor. The three-phase output of the inverter are applied to the PMSM block s stator windings. The load torque applied to the machine s shaft is first set to 0 and steps to its nominal value (11 N.m) at t = 0.1 s. Two control loops are used. The inner loop synchronises the inverter gates signals with the electromotive forces. The outer loop controls the motor s speed by varying the DC bus voltage.
