Does anyone know of reasonably priced 150v FOC controllers that can deliver 20kw? The motor is BLDC. I intend to run at 131v or 32S LION. I want variable regen and need around 200 battery amps.
I assume that you meantThere's some VESC based stuff on the horizon, but not anything that I have found that exists right now.
I've found a few sinusoidal controllers, but that's not FOC.
I know nothing about this controller other than what I can read from their product web page, but that says:I found the Kelly 8080i 144v variant, but it says sinusoidal, not FOC. Anyone know if it's actually FOC?
That's pretty clear: it implements field-oriented control.Kelly Controls said:It uses high power MOSFETs, SVPWM and FOC...
I specifically want the benefits of FOC. In 150v, FOC controllers are pretty rare.
Yes, that's what I was saying...I asked Fany at Kelly about the 8080i and she said it was not FOC. I asked if Kelly had anything FOC and she confirmed they do not. This seems odd, but she told me the same thing a year ago too!
I didn't see this before. Why would Fany tell me they don't support FOC? Thats nuts!
Right from the 8080i page in tiny print: "It uses high power MOSFETs, SVPWM and FOC ..."
Sinusoidal is a waveform, not a control methodology; the terms sinusoidal and FOC are not contradictory or incompatible.I specifically want FOC. So when I say, I've found a few options, I mean specifically FOC. Sunusoidal control is less than FOC. VESC based controllers, Nucular, ASI and others are FOC based controllers.
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.Sinusoidal is a waveform, not a control methodology; the terms sinusoidal and FOC are not contradictory or incompatible.
