The mechanical braking process of induction motors during short interruptions, and full switching off is studied in the paper. The approximate approach to solving a differential equation is used for the theoretical analysis of the braking process. The comparison of this approach with the exact solution shows its good accuracy. The used procedure is simple for a deep understanding of physical processes. It is shown that good results could be obtained for both full-stopping and braking due to sags if the right collocation point is chosen. This approach could be used for the study of different transients in electric motors and drives. It helps beginner students to understand clearly the main features of transients. However, it is also useful for experienced engineers who can easily obtain design formulas.
