Hi all,
QS205 50H V3I
SIAECOSYS 7230 100A
72V 25amph pack with 50A BMS
So I've gotten this far - I've wired the connections I believe properly such that it comes out without any errors. Ignition (orange wire), throttle, ethrottle, and battery wires. After much headache setting up the software I FINALLY got the hall test to pass (although the motor seems to be at a standstill on the blutooth hall test), with a hall angle of 245, coinciding with the manufacturer. Motor poles changed to 16 as well. Motor position flipped to 1 to get orientation right. There are ZERO errors in the sabvoton PC programming or the blutooth, its fault free.
After putting everything together and going for a ride, I instantly felt like internal resistance coming from the motor, especially when hitting the motor hard - and when I mean hard, I mean to go 10mph. This thing cannot go past 10-20mph because of like some sort of scraping, resistance going on in the motor. It feels terrible. Like the motor is choking when you give it the wrong amount of throttle, and by wrong I mean maybe giving it 1 extra volt of throttle. Like a micro-brake is applied rapidly. To be clear, this choking is only when throttle is applied, otherwise it rolls normally.
Is it the amp draw? I have a 72V battery with a BMS rated at 50A, and the controller is a SIA (basically a sabvoton) at 100A. It's connected to an x60 with 10AWG wire, that should be enough I think especially not to make the motor stall. Or programming? The hall angle should be correct, the poles are right, the orientation had to be flipped.. I'm really not sure what else there is to program. I guess the amp draw could be altered. I know the battery BMS is programmable. Wiring harness issue? Battery too weak, or possibly the motor is just defective? I feel lost.
