Design and Development of a In-Wheel Brushless D.C. Motor Drive for an Electric Scooter

Abstract

The gloomy answers to the oil crises compel to strive for sustainable road transportation. One such effort in this regard is reported in this paper. Due to the advent of power electronics; Brushless DC motor is considered as potential drive for automotive applications. Design of a direct drive, Brush less DC motor is presented. Many constraints have been considered, such as the size of the motor, maximum driving current and maximum output power. The diameter and the stack length are limited by using modern analytical tools of the prototype vehicle. Nobel analytical tools are used to obtain static and dynamic characteristics of the motor and geometrical verifications for low cost efficient design. A low cost electronic controller compatible for present application has been developed and discussed in this paper. The prototype is fabricated and tested on a lightweight electric vehicle. The performance results are presented and discussed in this paper.
