Abstrakt: The purpose of this article is to develop a Starter-Generator (SG) based on a synchronous electric machine with permanent magnets for spinning the rotor of a turbocharger engine. At the same time, there is a comparative analysis of the parameters of starter-generators with supply voltages of 27 V and 270 V. The analysis has showed that the existing design schemes of the SG are mainly designed for high voltage, due to the complexity of the implementation of the power converter. As a result of a comparative study of starter-generators with supply voltages of 27 V and 270 V, it has been found out that, in order to provide an output voltage of 27 V at a reduced speed, it will be necessary to use a step-up converter. Changing the configuration of the starter-generator to meet the value of 27 V is not possible because increasing the induced voltage in the generator mode will not allow achieving the desired value of the torque in the starter mode. Thermal calculations of the starter-generators at supply voltages of 27 V and 270 V have confirmed the possibility of providing all the necessary operating modes, in which the temperature of the active elements has not exceeded the permissible values. The total weight of the developed starter-generator with a supply voltage of 270 V has been 12 kg, while the total weight of the starter-generator with a supply voltage of 27 V has been no more than 11 kg. Thus, the conducted studies have shown the possibility of creating a starter-generator with supply voltages of 27 V, 270 V and minimum weight and size indicators for use in a turbocharger engine.
