Developing a Motor Controller for an EV Two-Wheeler: Suggestions and Design Tips Needed
Hello @here, I have a product I and my team have to develop from scratch. I have from Dec 16, 2024, to Febuary 17, 2025, to get a working prototype. The product is in the EV sector. It is basically a motorcycle, so yeah, a two-wheeler. We are to design and develop the motor controller in-house which is the first step. We intend to use a BLDC motor for this product. I am still going through the requirements and breaking it down, first thing I intend to set up is the pwm driver for the 3-phase system and we will go from there. I will appreciate the community input as we go forward. To an extent i will be sharing design files and firmware, but unfortunately, I won't be able to share some things. I will appreciate any suggestions and design tips from us @here as we will be moving forward

I started designing this motor controller and using stm32f103c8t6 and bare metal to set up the registers, I started up with generating 3 signals which are 120 degrees apart, my scope only has 2 channels so I couldn't have the 3 channels on the scope. If I had known when purchasing the scope I would have just gone for 4 channels.:8637blabbering: I had to send the signal through a low pass filter(no calculation was done, which I have to do) and that is what is observed on the scope, I am going to hook it up to Mosfet driver TLP350 and send the signals to drive the mOSFET.
