Rotor broken bar initially do not cause an induction motor to fail, but it can have serious secondary effects. Thus comprehension of rotor broken bar effects, and detection methods is useful for the safety of the motor drive. Effort of researchers ensure complex models with capability to describe broken bars effects, but these models do not help detect broken bar. Use of variable speed induction motor drives allow to exploit model based detection method. This paper proposes the use of a simply model that allows to evaluate effects of rotor broken bars and that can be exploited for fault detection or even for control. Detailed analysis of the model and results from simulation are presented to validate the proposed approach.
