Abstract :
The authors analyze and determine the effects of crosspath resistance between adjacent rotor bars on the steady-state performance of an inverter-fed high-speed cage induction motor. The performance of the induction motor drives for various crosspath resistances of two kinds of rotor slot shapes, a rectangular bar and a trapezoidal bar, is discussed on the basis of theoretical and experimental results of a 2.2 kW, 500 Hz, 15000 r/min three-phase induction motor. It is also shown that the equivalent motor resistance and leakage reactance change with crosspath resistance between adjacent rotor bars for various values of the fundamental supply frequency, the rotor slip, and the harmonics
