In article the non-sinusoidal of voltage at the nodes of electrical power systems with asynchronous loading is considered. Influence of the non-sinusoidal of voltage on the moment developed by the asynchronous engine is described. Influence of value of sliding of the asynchronous engine on possibility of its self-start is investigated. It is shown that frequency rate of the maximum moment and size of the initial moment of executive body of the working car have essential impact on possibility of self-start of the asynchronous engine also. The developed mathematical model for calculating the self-start of engine, taking into account the non-sinusoidal voltage is described. It is shown a block diagram of the calculation of the self-start of the asynchronous engine with non-sinusoidal voltage. The influence of the weight and size parameters of the asynchronous engine on the behavior of its speed at self-start is investigated. It is shown that non-sinusoidal of voltage leads to longer of self-start time of the asynchronous engine.
