Hi,

Can someone please explain why wheelchair motors are rated at 24V yet have a
12V brake? Is there a reason for the difference in voltages?

Cheers,

Michael

Michael,

Maybe they wire the brakes in series?

Well that's what I thought but surely you would want to ensure that both
brakes have the correct voltages dropped across them?

Can you give an example or link we can look at? Others on here probably
already know the answer but I for one would like to see exactly what you are
talking about - to satisfy my own curiosity.

Thanks !

Well I'd rather not since I saw it in a currently active eBay listing and I
don't think it would be fair on any prospective bidders. That said every set
of motors that come up on eBay I find have the exact same thing - and even
the pair I have are the same.

I was wondering if it was something to do with power consumption...lower
voltage = lower heat dissipation and thus longer running life.....
