Given:
At time t1, the sinusoidal magnetising currents of a 4-pole 3-phase induction
machine are given by:
i,(t) =/2Isin(0)
ib(t) =/2Isin(-120)
i(t) =/21sin(+120)
At a later time t2, the magnetising currents in the 3-phase induction machine are
given by:
ia(t) =v/21 sin(120)
İb(t) =/21sin(0)
idt) =v/2Isin(-120)
%3D
w = frequency
Note: (a) w(t2 - t1) < 27;
(b) the machine is at steady state and generating with rated torque.
