Three-wheeled electric maxi-scooter for improved driving performances in large urban areas

In the last years a growing number of four-stroke vehicles, called maxi-scooters, came into European market as a solution to solve mobility problems in large urban areas. On the other hand, in the field of purely electric vehicles, only low-performance electric scooter solutions have been presented in the past. Aim of this paper is to present a new, high performance, prototype of a three-wheeled electric scooter with extended driving range. This prototype is propelled by two AFPM wheel-motors placed on the rear wheels and includes integrated linear Hall effect position sensors. This solution provides a low cost alternative to traditional encoders and resolvers, which are not viable in traction applications.
