Results of research on the creation of electric transport

Gubin I., Sheshin A., Fominykh A., Opalev Y.

Multiple problems of modern motor transport are being raised more and more often. It becomes clear that the issue of its replacement is more relevant than ever in Russia and other countries. This article describes methods that are already being implemented in our country and will be implemented in the future, namely the transition to electric transport. On the example of project activities of students of Vyatka state University (Vyatsu), the prospects for the development of electric transport in Russia were considered. According to the results of a study conducted by students Vyatgu with the support of JSC "Elektroprivod", was created a prototype of a universal module that, when mounting to the frame of the scooter gives him a electric range and made the conclusion about expediency of use of electric transport of large vehicles (trams, electric trains, electric cars) and small (tricycles, Segways and e-bikes).

Keywords: electric scooter, motor wheel, brushless DC (BLDC).
