Unformatted text preview: the magnetic field is 1800 rpm. a) What is the frequency of the voltage produced in this winding? b) What are the resulting phase and terminal voltages of this stator? 5.3. (25 pt.) A three-phase Y-connected 50-Hz two-pole synchronous machine has a stator with 2000 turns of wire per phase. What rotor flux would be required to produce a terminal (line-to-line) voltage of 6 kV? 5.4. (25 pt.) If an AC machine has the rotor and stator magnetic fields shown in Figure 5-1, what is the direction of the induced torque in the machine? Is the machine acting as a motor or generator? Figure 5 ‐ 1...
