Multi motor electric drives are the systems, in which the torques from two or more motors are summarized. This summarisation may be done direct on common output shaft of indirect, for example, on the common load through individual transmiisions. In such a systems the problem of common torque distribution among motors exists. Usually this problem is being solved by equal distribution of torques among motors. There are some ways to achieve equal torques. One of them is overlaping of mechanical characteristics of motors by influencing separatly to the hardness and the speed of mechanical charecteristic of motor.
