I’ve been skating my new build around for a few weeks and have been having a lot of fun. No real problems with the VESC and it all seems to be working really well.
I did however have a small amount of cogging from a standstill start, nothing major - just what I imagine is the VESC figuring out which way is forward before giving you smooth acceleration. I would always make sure I was moving forward slightly or give a little push when starting off, but wondered if connecting up the sensor wires would make any difference.
My motor is a 190kv 6355 from Torqueboards, which has the small type sensor connector so I wired up an adapter with a larger pin pitch that fits the VESC and gave sensored motors a go.
I now have awesome smooth acceleration from a complete stop, and seem to have smoother performance overall when braking or quickly punching the throttle while already moving to get up to speed.
I do however seem to have gained louder motor running noise? I don’t understand the in’s and out’s of exactly how the VESC controls motors (I know the basics, BLDC/FOC having differing “styles” of telling the motors what to do…) but how could BLDC with or without sensors make a difference?
Before without sensors, the motor had that tell-tale BLDC whine, but now with the sensors added there now seems to be a louder lower pitched groan in there too, especially when braking. It has made me much more conscious of it when riding around the city compared to before.
Anyone else noticed a difference after they added sensors?
