CBR1000 regulator/retifier - circuit diagram wanted.

CBR1000 regulator/rectifier - circuit diagram wanted.

Do you have it in your workshop manual? Anyone know what are the specs of
the components inside. Mine has blown and I want to rebuild it.

Kind Regards, MARTIN

 

Hi Krusty - thanks for your input.
Just replaced my existing RR with Honda roigional ne for $200. Then
carefully opened up the burnt our one, digging out the pitch - I have made
up circuit diagram - I have the specs on the capacitor - trying to get the
specs on the diodes and the regulator. The regulator is used to contol the
current to the field winding (as this is NOT a permenant magnate type).

If I get the specs for these other commponents I'll publish the circuit
drawing and component specs. Parts will be less than $20 so we can all save
a lot of money!

OK guys - who can open up their old CBR1000 reg/rect and look at the part
number for the other components??!!!!

TIA

It may be a mistake to assume the part numbers on the components will
be industry standard numbers. It is not uncommon, in my experience,
for a manufacturer to have their own proprietary part numbers for ICs,
so instead of a TTL counter IC being marked '74LS393' it will be marked
with a P/N something like 2892846...

I wouldn't even bother trying to duplicate Honda's design. I would
simply design my own circuit, that is, if I were inclined to take on
such a project, which I'm not. It's so much easier to simply pony
up the $$$ for the real thing. My free time is far too valuable to
me for this sort of thing, I'd much rather be riding than designing
circuits. Perhaps something for the long winter months, though.

 

Mark -
Your quite right - the part number, for example, on the capacitor is N9004
BUT the specs also say it is 10UF 50V Rated to 125degrees C (which costs
1.39cents here).
So you can see the issue is real simple if we get the details of the other
(only) 2 parts we have a new RR for about $20 againt the $200-250 for new
repacement unit.
Not a bad saving for such a little effort! Lets hope others can help with
the other parts info.

Kind regards to all - Martin

If you publish the circuit, maybe someone will be able to understand
how it works and calculate the component values.

If you also publish pictures of the components, the chances of
identifying them increases.

 

Helge -
Thanks for your input - I will post the circuit as soon as I can to scan the
drawing.
Re the components - the only compnent of mine not burnt beond recognition
was the capacitor - I hoped someone else might have the other two components
survived for identification. -- see my post above...

All that would be necessary for an excited field regulator would be
a voltage regulator IC and a pass transistor to handle the rotor
current. The 10uF cap is most likely there to smooth out the supply
voltage to the regulator. Depending on the regulator chip's internal
reference voltage, you might need a couple of additional resistors
to divide the system voltage going into the regulator. It doesn't
really matter too much how Honda decided to do it, you certainly
don't have to copy their implementation in order to come up with an
equally good or even better regulator.
