Design and performance analysis of a 48V electric drive system for a cargo tricycle

This paper describes the main components of an electric drive in a novel electric cargo tricycle. The main components are a Mosfet inverter, an axial flux synchronous machine, and a Li-Ion battery package. The most important specifications and functions of the tricycle and the electric drive are explained. Particular focus is laid on the inverter design and the experimental setup that was used for the performance tests. Measurement results of lab tests and on-the-road tests are presented.
