The figure shows a rotating loop between curved 6 pole
faces, the poles cover 70% of the rotor area, for the rotor
the length is 50 cm and the radius is 20 cm. The rotor has
wave-windings (a =2) with 40 coils each 4 turns, If the
average flux density under each pole face is 0.4 T; answer
the following questions:
(a) The total number of conductors in the rotor.
(b) The geometry constant of the rotor.
(c) The flux.
(d) The induced rotor voltage if the speed of the rotor is 800 rpm
