ROTOR (Equivalent Circuit)

Under running condition the rotor frequency is scaled by a factor of “s” due to which all the parameters that are directly proportional to frequency such as emf and reactance also scaled by a factor of “s”. We considered the resistance to be independent of the frequency hence the rotor resistance remain same under standstill […]


In Induction machine both the stator and rotor winding carry current and produce flux due to which the resultant air gap flux is obtained by sum of the flux of the 2 winding and this resultant flux is responsible for inducing an e.m.f in stator as well as rotor winding. In an Induction machine rotor […]
