This article deals with the interrelationship of performance characteristics of the induction motors with the fillings windings that are dependent on the type of windings which are used during the repair. In order to decrease the labor-intensiveness of the technological process one could make wider use of a lathe for the mechanized working of this kind of motors. At the same time it could cause an increase in the losses in the magnetic wires, the size of power loss, the decreasing of its reliability, and the term of its operation. This type of motor could be mainly repaired by service station whose technological equipment is different from the equipment of big businesses. A solution for all of these problems could be a process of modernization of the stators' windings during the repair. This modernization includes the replacement of single-layer or single-double-layer concentric windings in favor of single-layer equipment windings or double-layer windings. There are examples of the realization of the different types of windings that could provide the minimization of copper use without increasing the labor-intensiveness of the procedure. At the same time it provides the decrease of power lose in the motors with invariably power factor.
