Hi guys. As some may have seen my other post, doing a bit of research in regards to potentially building vs buying an electric board. I’ve been scanning a few pages on here, as well as various sites regarding motors and motor controllers and have a few queries I’d be keen to see people’s answers regarding.
Firstly regarding the VESC as it seems to be the most popular choice/variant. For starters, the biggest thing I think I’ve found with this product is availability/supply. As per my original post, looking for something to use everyday as a reliable transport. Having an uncertain availability of a component could be concerning for this. Also as there seems to be a fairly large demand for VESC controllers, my concern is there seems to be a variety of places manufacturing them and this leads to inconsistencies in quality. If I couldn’t get a replacement from the same place, what issues will I encountered? I understand open source is good for some, but I see many potential issues here.
Being a unit needing precise programming to a motor for use,and apparently temperamental when not precise. This appears to open a large window for failure or poor operation as I’ve noticed a fair few on here having issues. Are there no pre-programmed/plug-and-play options?
Most/a lot of motors I’ve come across are un-sensored motors. I’m presuming 2 things from this. Firstly, is that there would be no ability for RPM limit programming? Second being from assumption and a couple of videos I have come across, is that low speed control would potentially be jerky or in a way “stepped” speed control. Anyone gone to sensored motors and programmed them for this reason?
I am most likely going to run dual motors. I’m yet to come across a motor controller to run 2 motors from the one unit, but rather 2 VESC’s either being connected as master and slave via a CAN connection, or 2 separate VESC’s sharing one output from a reciever. In either case I’ve seen they still need to be programmed individually and have noticed people with various issues in either situation. Additionally, in a video I found on the vedder page, I noticed the motors possibly seemed to be spinning at slightly different rates? Guessing a side effect of running un-sensored motors??
Cheers for any and all feedback guys. Sorry for all the questions
