Dale,
Two motors is out of the question. Not enough space or money. It will
need to be a 6.7"X12-13" ADC or D&D motor then.
This is a good company for freewheels. They are probably who I will
order from, but it's not all that clear what's what from their website.
The sales rep suggested the MT-130B, but that's too big, so I think,
like explained in the last message, that I'll turn the drive shaft down
to 3/4" and go for the MT-60, though I'm still not sure what the
difference between the A B and C versions is. I assume it's mounting
options. Hopefully, I can call tomorrow to clarify and possibly order.

If you want a good list for overrunning clutch companies, this is the
best I've found so far:

i agree with jeff about he need for two motors for 1000lbs
as for "4) Do any of you use an overrunning clutch coupling, or something
similar, so the motor shaft isn't directly linked to the final drive?
" i would also like to find something like that.

Hello all,
Great list. I've been following along for about 3 months now and it's
been very helpful to hear the comments and ideas from the members.
Travis' post has got me going, 'cause I'm interested in motors too.
There is a 1975 Honda Gold Wing disassembled in my basement and I'm
trying to figure out how to rebuild it. Which motor to get is the
current question and it's such a pivotal one that the rest of the design
is waiting for it.
Here are a few questions that I'm struggling with.
1) What's the difference in quality between ADC and D&D?
2) Can a PMG-132 push my sled at 60mph for 10 minutes without
overheating? There's another 5 mi. of city driving on top of that to
get to my job. Can it be done on 60v or or should it be done with 72v?
3) What's a typical watt/mi estimate for a bike that's around 1000lbs.
with rider? I've been using 300watts/mi. in my calculations. Is that
close?
4) Do any of you use an overrunning clutch coupling, or something
similar, so the motor shaft isn't directly linked to the final drive?
An OCC is basically a freewheel. My diesel has a mpg readout in dash
which, even if it's not perfectly accurate, definitely shows that
disengaging the engine when it's not needed and coasting to stops saves
a lot of fuel. I'd like to do the same with the EM without having to
add a clutch. It would also eliminate any concern over the motor lockup
issue that was discussed recently.
Any thoughts or suggestions would be very much appreciated. Thanks,
Seth
