150v FOC controllers wanted

Sinusoidal is a waveform, not a control methodology; the terms sinusoidal and FOC are not contradictory or incompatible.

This is well known, but sinusoidal also embodies a specific form of motor control that isn't trapezoidal or the full monty that is FOC. I have not seen an FOC controller that didn't implement sinusoidal control. FOC takes things a lot further in how a motor is controlled beyond feeding the phases a sinusoid.


I'm pretty sure...aka highly skeptical that the 8080i is really FOC. IF it was, why don't they blaze that across the top of the page? Instead it's in tiny print, buried in a paragraph. It's almost like "We want to fool you if you buy into this one skimpy line of text that includes FOC. However, when you discover that our controller isn't FOC, we can fall back on the fact that we made a really small deal about it."

When I asked Fany if the 8080i was FOC or not, she got pissy with me and then emphatically stated that it was NOT FOC. Soooo...DELETE that "FOC" from the description already!!!

IF anyone cares...
This is a spin-off from Rion scooters. The are making VESC based controllers in a few variations. They all use TO-247 mosfets and unlike the easily destroyable stuff coming from Trampa and FlipSky, include opto-isolation, TVS and other protection devices.

www.tronicsystems.com was purchased in September 2021 and has barely gotten set up. Content shows up and goes away again. The e-commerce functionality is not yet working. Contact them and you might get an email from a Rion or Tronic address. I have emails with Tronic addresses and then the signature line is someone from Rion. It all the same folks. They have gotten a lot of interest in the VESC controllers they use in the Rion scooters and decided to sell them separately.

The Tronic 250 is more or less a direct competitor with the 100/250 from Trampa, just much better made and I beleive uses the IRFP4468 mosfet. I'm not sure of the mosfet count, but either 6 or 12. What they said about this controller, "The 250’s has nothing to do with the trampa design! It’s a completely different product with higher grade components and higher outputs at 21s. Other vesc are blowing up easily." I had just asked if this was a copy of the 100/250 from Trampa.


The Tronic 400 currently shows out of stock, but really they are waiting for the first batch of them to get into their hands. I can see using 2 of these on my Zap scooter at 82v to replace the forever wonky Nuculars on it. It did list some specs, but that got removed until they have stock on hand. They are rated for 28S and 400 phase amps. When I mentioned that Nucular is $10 more, rated for 500 amps and has an LCD, they were pretty defensive and emphatic that this controller would destroy a Nuc 24 fet. It is higher voltage at 28S instead of 22S. We will see! I'll get 2 of them just as soon they make them available. This is also a TO-247 12 fet controller and uses the IRFP4321 mosfet.


They listed a Tronic 750 for a while until I started asking about it. Then it got taken off their web site since it was not ready for sale for "another 45 days". It's made with IRFP4321 150v mosfets, 160v caps and most everything else is 160v components. They would not talk about this controller very much other than to say 750 phase amps and 30S. I'm guessing it is 24 fet since it's essentially double the amperage of the Tronic 400. They listed it for $800...might need 2 of them for the XM3000 project. I tried to push them on further information and they were careful to not give out details. It's all 150v+ components so 32S shouldn't be a problem.

These came down too and had no specs, just blank pages. The listed a modular BMS and a DC-DC. I asked about them and they would not say anything.
