Abstract
The applications of electric scooter will be very competitive in the future market; therefore, development of high reliability and low cost motors for the electric scooters still has very high potential. And the selection of compatible power drives for permanent magnet DC brushed motor is the main research topic. The adoption of high energy, residual flux, and cohesivity NdFeB magnets could largely increase the air-gap flux density and reduce the volume and weight of the DC motors. In this thesis, one-dimensional analysis, namely conventional, was employed for the DC motor design. With the basic dimensions calculated for the two-dimensional magnetic flux distribution. Finally, a better design was obtained on the DC brushed motor. The finally design has satisfied the original requirements and been available for future verifications after comparing the different results with the help of dimensional variation analysis.
