Re: [Electric Boats] using dual DC motors with one controller

 

Yes, I was planning on wiring them in parallel, but physically connected end to end.
I like your idea for mounting with reduction options.
I will have to check my space to do that.
Any chance there is an available mounting hardware for that type of arrangement?
Suspect it would be a custom build though

Thanks

I could be wrong, but I don't think you would want to connect them serially (if that is what you mean by end-to-end). You would need a voltage of 180 to do that effectively. You should not have a problem connecting them in parallel.

If you mean a mechanical end-to-end (or same shaft) connection, then that should be ok - still with parallel wiring. I personally would prefer a side by side mounting with a belt and reduction drive to the screw shaft (in a triangle arrangement), but your needs (and space) could vary.

Hi
I am wondering if it is possible to run 2 identical DC motors from the same controller.
Part of me says it should be OK, but I also think they may fight each other and waste power.
The concept would be 2 90 volt DC motors attached end to end and then to the drive of my boat.

Any info appreciated

Mark
