Development of a Differential Electric Drive of a Starter-Generator based on a DC Motor

This paper discusses the usage of an automobile starter-generator based on a differential electric drive. The advantages of using this solution over existing analogues are given. An important factor is the usage of an integrated flywheel in the design of the planetary gear, which is shown as a ring. Further, the design and optimization of a starter-generator with a differential electric drive based on a DC electric motor is carried out. The YaMZ-236 diesel engine was selected as an experimental internal combustion engine. A model of a DC electric motor, a mathematical model of a planetary gear and a diagram of a starter-generator control system have been created in the ANSYS software environment. The mass of the integrated flywheel has been calculated. The graphs of transient processes of the starter-generator operation are given. The comparison of weight and size indicators of the obtained starter-generator with the existing separate application of the starter and generator is shown.
