Hi everyone, long time no see, glad to see everyone and the site are doing alright.
I'm fine, working, learning, living, family, garden, you know;
still have my yamaha and the aprillia, life is good.
So... does anyone have any experience with e-bikes?
I want to motorize my homemade sidecar bike, remember?
the one I made from an old bed frame, yup that one.
http://suzukisavage.com/cgi-bin/YaBB.pl?num=1337645823/0I have had it for over 2 years now and the thing is solid and
has needed no repairs so far, but understandably has always been a
bit on the heavy side and my limit is about 5 miles on flat terrain,
so what I want is electric assistance so I can go further & uphill,
besides I'll end up busting my knees if i don't do this.
This is what I have so far (fleabay):
- (1x) 250w/36V, brushless hub mounted on reenforced 28" front rim
- (3x) 12V, 12AH/20HR deep cycle 10 year/2000 cycle batteries
- (1x) universal 12-40V 20AH voltage (RPM) DC manual regulator,
the dimmer kind with a knob to regulate fan speeds, etc.
- (1x) digital voltage meter
I still have no controller but I think I do need one
since little did I know these things are NOT DC! but
a modern form of AC running at a frequency of 15-40k
pulses per second, however people claim they run these
things on direct DC with no issues, is this true?
So
my main question is, what is up with the 3 cables from the motor?
after some poking around I found out that one is (-) and
the other 2 are (+) but the two positives are not the same;
so far I've only tested the wheel with direct 12v DC,
one (+) gives the wheel a little jolt and the other one
a strong jolt, but if I briged them, both (+), they
make my safety fuse short out.
I read somewhere one of the (+) motor terminals is 5 volts, why?
Should I give it a try with 24 or 36v direct DC
on the (+) that gives the strong jolt and just
ignore the other (+) and see if I can make my
wheel spin or just buy a controller?
Any other tips, ideas or mentionable experiences with
these things that anyone would like to share?
Thanks in advance.
