VESC SIX is made to last and perform under more extreme conditions and can be used with equipment having high amp draw and high ERPM, low resistance motors, high KV motors etc. The applications are endless. VESC SIX makes use of all the new firmware features like three phase measurement for super stable and smooth FOC. I’m pretty sure we will see a lot of different VESC designs soon, and some will be more expensive, and others cheaper. You can buy a smartphone for 70 or 700 these days. There are probably good reasons to buy one for 70, as there are good reasons to buy one for 700.
BTW: 150K ERPM is tested, up to 80A + continuous is not problem, depending on your heat distribution.
Motors with very low resistance do also work just fine now. Hardware 4.xx simply can’t handle that.
We have switched from full forward to full backwards in 0.05 seconds, using quite big motors in FOC under load. Some robots do such crazy fast movements. So you want the hardware to cope with that.
Not everyone uses these controllers for skateboarding! You have no clue for what these ESCs are being used for, other than skateboarding. The applications are endless. Benjamin is being approached by all sorts of startups and well established companies. So for sure he wants to show a hardware being without any compromise and up for many tasks.
Firmware and hardware need to go hand in hand.
Assuming you are outside Europe, the VAT does not apply!
Price is as low as 187 Pound if you buy it with a board.
If you buy a twin, they cost 216 each
If you buy 4 VESC SIX, you get them for 208 each.
If you buy 10, the price will drop to 187.
If you compare that to existing hardware, cheaper to make, the price is quite realistic.
Its is a superior design to hardware 4.xx and the price is simply according.
You also have to note that only a very few vendors donated something to Benjamin.
So they did not price in R&D and project support, but rather used Open Source availability to lower the price.
You can easily spend 500+ € on a single motor controller that is as smart as a potato, allowing only BLDC and voltage control. VESC-based hardware is very cheap if you compare that in the market - plus it can do all sorts of things other ESCs simply can’t. It is a full scale industrial grade controller at the price of hobby equipment. So you are all lucky that this piece of software and hardware exists for such a low prices.
