Hello, I'm Max and since this is my first time here, I'd like to send out a big thank you to everybody posting on this great forum! 8) It already helped me quite a bit and I'd love to get involved more in the future.
Now, I'm building a 4 kW cargo eBike for city riding mainly, but I'm kind of stuck and could really use some help! Running a QS 205 50H Version 3 Motor on a 24 FET Infineon 24-IRFB4115-80A Controller at 24s Voltage (102 V). I have some issues with the motor stuttering quite hard and suddenly stopping at low speeds. I made a video of the problem to illustrate. The stuttering is quite violent moreso than you can see in the video. I'm thinking this might be a problem that has occured before or someone knows of the issue.
I already checked hall sensors with a multimeter and they seem to be okay. Also the three phase wires of the motor seem to be okay on a first check (held them together and felt quite some resistance when turning over the motor). Still, my next step would probably be to disassemble the Motor and check all wiring, I'm suspecting a half broken phase wire. Do you guys agree, or could it be a controller issue? Or a problem with the power supply? I'm running on two 51V power supplies in series at the moment, as I don't have the battery ordered yet.
