Brushless DC (BLDC) motors are continuously replacing brushed DC motors in low power drive systems as they offer better efficiency, longer life and smoother torque delivery. In my final project I will show the whole development process of a hybrid drive train consisting a BLDC motor and a traditional combustion engine. The cause of this hybrid development is that a team consisting of 20 BME students participated in a competition for which we had to modify a go-kart according to the race requirements.
In the beginning of my thesis I will show the different kinds of hybrid systems which are common nowadays. Next I explain the basic operation and theoretical background of the BLDC motors and their main benefits. After the introduction of the BLDC motor I present the design steps of the Printed Circuit Board (PCB) of the BLDC motor controller board. The board includes the MOSFET transistors and the dedicated driver IC. The logic signal is generated by a DSP.
In the end of my thesis I show the major development opportunities in connection with hybrid drive trains and BLDC motors that I was not able to implement into to go-kart till the beginning of the race.
Finally I summarize my final project and also my personal experiences during the development.
