In this paper, the analytical solution for the determination of induction
machine acceleration, i.e. acceleration-time characteristic, during no-load
direct start-up is proposed. The proposed dependence is derived from the
Kloss equation for torque-speed relation for the induction machine. Also,
the analytical solution for the maximal value of the acceleration is derived
in this paper. The results obtained using developed expressions are compared
with corresponding results obtained using the developed Matlab/Simulink
model for analyses of the induction machine starting the process. Therefore,
very high degree of accuracy is obtained.
