dual brushless motors

just had a question. if i use 2 brushless motors do i need 2 esc's or can the motors be wired together to go to one esc.

thanks

two esc's...

[nl12]

Unless...

[steveo]

depends on how big the motors are and what esc you are using , you could use up to 700 size motors on a evx esc.

[sleebus.jones]

Why not just size the system properly for one motor and be done?

[jhautz]

you could use one, but the motors would need to be identical and timed to each other. Not that easy to do, but its been done.

I agree. one properly sized motor is more efficient and just as powerfull.

But two gets you 'cool' style points...

:P :D

reason for 2 motors is cause im going to start building a truck and im going to enter the worlds fastest rc car challenge.

ok and thanks you guys answered my question.

[suicideneil]

Well, that does change things though, since you are building a truck for a speed record. To find a single motor as powerful as a couple feigao XLs, you'd want something like a massive Neu or lehner costing 10 times as much, and esc costing.... I wouldnt like to guess. JohnnyMaxxima has a Gorillamaxx based truck with twin 7XLs running on 5s each- and Bk9920s I think it was-that should be a good point of reference for you.

steveo - evx is not a brushless controller it is a brushed controller...

Jef - I guess you could ensure that the rotor was at exactly the same point... I suspect it would be difficult to achieve with variation between motors etc

Dual BL will not have that much of a gain over single BL, considering the extra weight involved. With dual BL, you pretty much need twice the batteries as a single motor.

My Savage will be entering the competition, with a single KB45 10XL (1200 kv) running on 10s2p A123, with a CC Phoenix-HV110. It's geared 20/46 with a center diff (no tranny), for a theoretical top speed of about 65mph. I haven't reached top speed yet because the suspension is too soft and the oil in the center diff isn't thick enough.

ok now would a xl motor push our more power then a L motor?

[MetalMan]

For continuous usage, yes. At the same power level, a shorter motor will generate more heat.

so if im only using it for a little bit of time could i use a L motor.

[zeropointbug]

i would stick to one larger motor

what are you running this in?

a large Neu motor should work wonders for speed records
