Transcribed Image Text:
A single phase synchronous motor can be represented as two mutually coupled coils as shown in Figure (see the attachment or look at the Tutorial 10). Inductances of the coils are given by: L11-0.9 (H) L22-0.7 (H) L-12-L21 -0.9*cos(Theta) where Theta is rotation angle of the movable coil (rotor). Find average (over a period of rotation) torque acting on the rotor under the following conditions (applied simultaneously): -Coil 1 (stator) is fed by AC current: i, (t)- 13'cos(w't) (Amps): -Coil 2 (rotor) is fed by DC current: i₂ (t)-7 (Amps): - Frequency of rotation of the rotor is the same as frequency of the AC current of the stator (w): -Phase shift between the stator current and the rotor rotation is 45 degrees. Express your answer (in Nºm) as a magnitude (no sign) with two digits after decimal point (as in 12.34) A single phase synchronous motor can be represented as two mutually coupled coils as shown in Figure (see the attachment or look at the Tutorial 10).
