Re: AVIAN featherweight mid drive

Hi guys, I'm trying to figure out the best way to encase VESC and heatsink it at the same time. The problem I'm having is with capacitors. They are in my way. Would it be electrically and electronically sound to move capacitors a little away from the board and put the power switch between the board...

Re: Couple of questions...

snip snip re vesc amps settings... 1. Vesc Amps setting. I don't quite get the relationship between the Motor Amps, Battery amps and Absolute Max on the Motor Config page of BLDC tool. Lets say I have a motor capable of 80A, a battery 100A, and the vesc itself can do 50A - all sustained Amps. What ...

Re: Couple of questions...

Been testing the drive on my bike and having a lot of fun and I love its simplicity. I guess I am kind of taking it a little outside its intended use, but hey, that's how we have fun, right? I have a couple of things hoping people might be able to give me some tips on. 1. Vesc Amps setting. I don't...

Re: Kepler Friction drive comes of age.

DRV8302 fault code Did you use a 4.12 VESC oder a VESCX? FOC? FOC is known to cause DRV errors on 4.12 hardware - the only way to circumvent this is to either go VESCX or the new (way more expensive) VESC6. At 7S your 330kv motor also caused 7*4.2*7*330=67914 ERPM which is more than what the VESC i...

Re: Kepler Friction drive comes of age.

I set the drives to climb and push into the tire just hard enough if you hold the motor still while it is fully engaged and try turn the tire you can only just make slip with significant effort. Never had a motor bearing fail however, you are right, I only use about 350W max. I have run up to 700W ...

Re: Kepler Friction drive comes of age.

Kepler- Looking forward to the bracket- I think you have designed a beautiful solution for those looking for a little help without transforming the bike. While I am not going for the cheapest setup I think it may be the easiest electronic setup to balance with your simplified elegance. Here is a br...

Re: Alibaba 50 dollars VESC worth it?

Got the VESC yesterday. First look: Looks cheap. I'm not sure what kind of DRV is normally used but this has the Texas instruments logo on it. They also used vedders capacitor pcb with the three capacitors. The phase wires are only 16 gauge and the power wires are 12 gauge. They heat shrinked it, s...
