Abstract
The author proposes an improved version of the mathematical and computer
model of a three-phase induction motor in the three-phase braked coordinates (in the
three-phase stator reference frame), which proves the correctness of the starter winding
asymmetry considerations in electrical machines. The chapter presents the parameters
and characteristics of an induction traction motor type STA-1200 manufactured in
Ukraine. A comparative analysis of the simulation results for intact and damaged
motors has been carried out.
