TWO ESCs to one Motor??

[Darin Jordan]

Has anyone out there ever tried running TWO Brushless ESCs to the same motor?? In other words... two identical ESCs, with output, input, and control wires, all wired in parallel, to a single motor?

Just curious...

Darin, what kind of a monster boat are you building that needs 2 ESCs for a single motor? JIM

PS: See ya at the Nats!

I believe that Joerg has done it.

Pair of 300 amp esc's? N2 project?

[Boaterguy]

I was going to do it, i will on a small motor when i get a pair of hk ESC's for my twin airboat.
my only concern is that one ESC will pull it accross to the next winding and the other ESC will get confused because it didn't spin it.
i'll post a video when they arrive (should be next week)

600A N1 rigger eh?

If you use half of each motor winding to each esc, so motor would pretty much have 6 wire leads you can do it. So then each esc is not touching the other one electronically. The voltage in each will be the same through both since there is only one magnetic field in each core. You can test each individual strand of the motor windings with a multimeter to make sure you have the same individual wires on each side.
Good luck!

Jacked, I think I understand what you mean, you take off the connectors and split the individual strands into two separate sections, and then you have six?
I'll try it normally, do you think it will blow the ESC's?

Lehner has six connectors on the back of some of their large motors to do just this, use two controllers to enable higher current draws.

Go for it Darrin, just do some searches, their is a blurb in one thread somewhere with pics and all. I think Peter Z. knows the build and can maybe chime in with more info.

If you use esc's that have program boxes, just use a Y harness to program them the same at once

Actually the 6 wire Lehners are for connecting Delta versus Wye winds. The 12 connection Lehners have parallel windings for twin ecs's.

I had a chat with Castle Creations and it's NOT something that will work. Two controller boards trying to operate one motor = BAD THINGS...

No biggy... was just trying to see if my older Barracuda 80 ESCs could be used together for an small N2-Hydro app...

Tyler... Somehow, I think that no matter HOW hard I try... N1 will never draw much more than 50A or so... the motors are the limiting point here... The resistance of the windings and such just limits how much it'll pull. I can throw as much prop as I want at it, and it's tough to even get it above 40A... Just hits a wall...

Tony... that's similar to the Castle 240s... or even the older 125s... They are two FET boards. BUT, they are controlled by a single controller.

There IS a way to marry up the two B80 FET boards, but getting the controller jumpered between the two boards may be more work than I'm willing to undertake.

If you look at them, the Hydra 120s are a single FET board. I think they are essentially the same as the B80, but are rated higher due to them having water cooling, where the original B80s didn't.

I have two B80s... one with the older "legged" style smaller FETS, and one with the newer surface-mount style FETs... I'm going to watercool the heck out of them, and see if it'll hold up under the amps I'll want to draw... Needs to be able to sustain 100-125+, I imagine...

ooops, sorry...
