Question 22
EEMCQ1 markNeeds review
The four stator conductors (A, A′, B and B′) of a rotating machine are carrying DC currents of the same value, the directions of which are shown in the figure (i). The rotor coils a-a′ and b-b′ are formed by connecting the back ends of conductors ‘a’ and ‘a′’ and ‘b’ and ‘b′’, respectively, as shown in figure (ii). The e.m.f. induced in coil a-a′ and coil b-b′ are denoted by Eₐ₋ₐ′ and Eᵦ₋ᆼ′, respectively. If the rotor is rotated at uniform angular speed ω rad/s in the clockwise direction then which of the following correctly describes the Eₐ₋ₐ′ and Eᵦ₋ᆼ′?
