Webb31 okt. 2024 · Different from rotating induction motor (RIM), linear induction motor's (LIM's) structure is asymmetric and its secondary part consists of a sheet of aluminium with a back core of iron . When the primary part moves, new continuous eddy currents appear at the entry of the primary part and disappear at the exit part [ 2 ]. WebbEquation 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.
