Find the stator currents when (i) the rotor is locked and (ii) the rotor is running at 157.1 rad/s. It can be assumed that the input is a balanced two phase voltages at 50 Hz. The parameters of a two-phase PMSM are as follows: r = 122, L = 10m H, La = 4.5mH, Af=100m Wb-t, P = 4 Obtain the stator currents in the rotor reference frames if the actual stator currents are given as follows, K-4 [sin(t+6)] P cos(@0,1+6)
