s constant. If the torque the motor is to generate is toremain constant, it being proportional to the product of theflux and the rotor current, there must be an increase in rotorcurrent on account of the decrease in stator flux, in orderthat the motor carry its load. The required increase in… … If the resistance of the rotor be increased, the e.m.f. required to produce a given rotor current must increase, amin order that there be an increase in rotor e.m.f. there musbe a decrease in rotor speed. 421.
