Electric drives for light e-scooters

Abstract

In  the  next  years  is  expected  an  important  rise  in  sales  of  electrical  scooters  in  the  entire  world  but  especially  in  China.  In  order  to  address  this  challenge  the  electric  scooter industry has to be more competitive in the transportation market and therefore important   improvements,   in   terms   of   energy   density and costs, have to be done in the electric storage system and in the electric propulsion system. In this paper,  an analytical and experimental comparison of two different drives for electric scooters is carried out. Both are permanent magnet synchronous outer rotor motor drives but one placed inside the rear wheel andthe   other   connected   to   the   wheel   trough   a   mechanical   transmission.
