In a laboratory experiment, a single phase motor is used to drive a 3- phase, two pole, 60 Hz synchronous generator. The motor input current is 10 A from a 220 V source. The generator has a 500 turns field coil carrying current I,= 8 A. The generator mechanical dimensions are as follows: gap g = 20 mm rotor radius r = 30 cm Assuming a lossless case, find: machine length 1 = 1 m armature coil turns N₁ = 24/phase (a) The motor speed n (rpm) (b) The motor torque delivered to the generator (c) The generator induced rms voltage/phase (d) The flux o that cuts the aa' stator coil when it makes 30° w.r.t. the field coil.
