Broken Rotor Bar Fault Diagnosis in Induction Motors using Resampling Based Order Tracking Analysis Method

Induction motors are the most popular motors used in the industry because of their simple structure, steadfast operation, and high efficiency. unexpected failures of these motors reduce the production capacity while increasing the maintenance and expenditure cost. so condition monitoring motors and troubleshooting methods are highly necessary for the electrical motors. in this proposed study, the effect of broken rotor bar faults on motor current signal in three-phased motors was examined under stationary and nonstationary conditions. the proposed method contains clear information about the fault under both operation conditions.
