Bosch Motors

[Gaseraki]

thats a point if you ran them in series on 24volt would they be ran at 12volts each?

[woody]

Yes.

[blazerbotics]

But the motors will have double the current being pulled through (eg each motor is pulling 40amps, then the total 80amps must pass through each motor). So expect them to get warm.

[Gaseraki]

Does that mean the speedo will have to handle more amps?
So it would still be best to get a 12 volt speedo and run the motors on a single 12volt battery pack in parrelel.
Or no difference running them on 24volts with the motors being in series?

some errors in the above advice, wont go into it all, but to save you blowing things up, although they do pull 12v each from 24v total supplied if equally loaded, do not lock a wheel, or something unwanted happens to the other.

I currently run...

Edgehog, 100kg, runs 2x12v 400W motors for drive, a single hawker 12v SLA battery, sidewinder controller, no problems at all.
has run 18v and 24v, without problems, but Edgehogs gearing is wrong for 24v, so it pulls too much current for my liking.
Speed at 12v is slowish but ok, 18v is good, 24v is a bit silly.

If you want any info on the sidewinder with bosch 400s Suran, drop me an email and I can give you more details about Edgehog.
