yeah, I was mocking this forum

What is a single IMU? Or what’s an IMU anyway? Why couldn’t any esc be used in tandem on a motor?

He meant MCU, the processor on the controller. The IMU contains an accelerometer, gyroscope etc. there are used for balance builds.

The reason single MCU controllers are able to do this and dual MCU controller are not probably has to do with timing. You have one processor driving two power stages instead of two processors driving their own power stage.

Driving a 3-phase motor requires switching fets on and off at sometimes over 20000 times per second. It would be significantly harder to synchronize two separate controllers so nothing blows up.

But what of powering a single motor with two escs? I thought that could be done with any esc.

Not really, this has been a thing for years on e-bike :+1: My first trashed project implied using 6 phase motor which required 2x 3 phases esc for a motherfucking asphalt terror e-bike. I’m glad I never built it, didn’t have enough knowledge yet to play with what monstrous components I had in house :joy: Would have burnt or crashed something too expensive for my purse.

Anyway on paper you can always delay the signals so both ESC fire phases in sync according to how fast they communicate together. Or buy a 6 phases motor, that’s the safer bet and you’ll get that double torque anyway.

This is different though, you’re not electrically connecting two esc’s together. On a 3-phase motor if the timing is wrong you could have a dead short.

Weird as I’ve heard of it being done successfully

Unless I’m missing something your link has two answers that say its not possible.

Yea. You’re not missing anything. I’ll post one above of a success but I guess the escs each have a single mcu

Yeah, a 6 phase motor could be driven by 2 escs theoretically since the phases are isolated. In a 3 phase motor, the two escs would share phases and could short if the timing isnt perfect.

For everyone that hyped thinking he had them in stock, this is just custom [beta] firmware based in FW 5.03. Still no stock :sob:

Can anyone comment on these. How do you like them? I went ahead and ordered a pair of the R7’s. I’ve been looking for a HV VESC and I really like the specs + design aesthetics of these units. Now I just have to figure out how to top mount two of them within a small footprint. I’m thinking I’ll put them back to back against a thick, piece of aluminum, pocketed on each side with 3d printed caps. I mean, it would be bad practice to have different length phase wires, would it not?

Glad these don’t have an anti-spark switch built in, until someone makes socketed components you can easily swap out without soldering. I’ve been wondering if that’s possible. Isn’t it the resistor that tends to go bad in an as circuit? What if you made the resistor socketed? Just give it some screw terminals. Or, is it more complicated than that?
