Abstract :
A comprehensive analysis of the axial force experienced by the rotor of an induction motor, as a function of slip, is presented. It is shown that the varying saturation along the stack of a skewed induction motor considerably affects the axial force due to skew. The calculated values obtained for the force are found to compare quite favourably with experimental results. It is also established that the force decreases with increase in the airgap length.
