Nettet30. mai 2024 · In a DC motor, it makes sense easily because input voltage, back-emf, and rotation, are all in the rotor. So when the rotor speed is low, it cuts less flux, and creates low back-emf. When the rotor speed is high, it cuts more flux, and creates higher back-emf. A nice feedback loop. But it seems reversed for the induction case the way I'm ...

NettetEquation 1. In the supply-frequency equivalent circuit, the secondary e.m.f. is E 2, rather than sE 2, so to obtain the same current in this model as given by equation (1), we require the slip-frequency rotor resistance and reactance to be divided by s, in which case the secondary current would be correctly given by.
