Abstract: A new mathematical model –built using the synchronous drive system with electrical shaft was introduced and the effect of the additional resistor on the synchronous capability and recovery time of the system was studied and its optimal value – to be added to the common rotor circuit of the system -was determined. The results show that the relationship between the additional resistor and the system's synchronous capability depends on the difference of loads. It was found that increasing the additional resistor value - with increasing the load difference - results in better synchronous capability and recovery time. However, the system efficiency decreases. To overcome this main drawback, a controller block was added to the model to determine the optimal value of the additional resistor according to the difference of loads on the motors' shafts. The suggested model was verified experimentally using a crane system consisting of two identical induction motors, where th!
e system load (total load) is distributed on two motors depending on the load position. It was found that the experimental results closely match the results obtained using the proposed mathematical model The synchronous capability and recovery time for the synchronization process of the system will be faster in implementation than the calculated values because of the presence of the gear box were the speeds are reduced to the tenth of its maximum speed
