An approach to optimizing the flux linkage of the rotor of an induction motor is considered when the motor operates in a vector control mode with indirect orientation in the direction of the field. In this system, the expression for the frequency of the rotor e.m.f. contains the rotor wind...
The paper presents an analytical and experimental study of the additional losses which occur in induction motors supplied with nonsinusoidal waveforms. Measurements on an inverted induction motor are used to show the importance of losses due to skew-leakage and end-leakage fluxes, and to verify the...

Primary core and solid secondary eddy-current losses are determined in the electromagnetic topology of a tubular linear induction motor (TLIM). The nonlinear B-H characteristic, hysteresis and skin effect are considered in deriving formulas for eddy-current losses. A means to reduce these losses in...
