Multi-motor electric drives are widely used in many industries due to increased reliability, weight and size, and other parameters. One of the drawbacks of multi-motor electric drives is non-uniform load distribution. The reason lies in disorder in parameters of the motors of the same catalog data. Determination of uneven load distribution and load balancing between the motor is considered in this paper. The analysis of mechanical characteristics obtained of the two motors is performed. The variants of load balancing by changing the frequency and voltage amplitude is considered. The paper deals with a simulation model which allow to investigate the two motor electric drive with a single load. The results of research in the form of transient responses with introduced adjustments at different frequency and voltage are also given herein. Studies have shown that in the process of adjustment the frequency and voltage must be changed depending on the magnitude of the load torque of electric drive. The method of load balancing can be applied to induction motors which have the same number of pole pairs.
