So I want to build a some kind of electric vehicle, so I thought it would be a good idea to learn how to build a brushless dc (BLDC) motor controller and how to control a brushless dc motor. Why brushless and not induction? Well, first of all, as of my background in RC, I can use one of my RC motors to test a controller prototype and I know where I can get bigger RC motor with more power if I need it. Plus BLDC motors are simpler to control than induction motors, so that was also a big factor why I decided to start from here. I'm scheduled to graduate spring 2016, so I hope I can you give you guys a nice project log on how this will be progressing from here.
I have planned my thesis work on these steps with the first step being the absolutely mandatory one and the hereafter being "stretch goals" to work on if there is time:
- Design and build a simple, working sensored BLDC motor controller using hall-effect sensors
- Learn how Battery Management Systems (BMSs) work and build one for the EV
- Design and build a vector controlled BLDC motor controller for increased running efficiency
- Build a simple switching mode power supply charger for the EV
