Super Series R/R Market Survey

[salty_monk]

So anything with 600+ number could be used on our bikes... is it me or is there no prices on that site?

[Cassius086]

Jim, I would be in for one if you decided to make/market/sell them! A boost in power AND fuel efficiency? Wahoo!

[pete]

I might be up to requiring one by the time you get it designed, but would really depend on $$$ conversion to Aus and shipping costs... might blow it all out of the water for me...

Quick edit... forgot to say your idea's a good one...

[Dogma]

I'd take one, or a kit, if the numbers favor such.

[Calvin Blackmore]

I will take one as well
That is if it will work on my bike.
I have spent 600 plus dollars in preebay days for oem reg rects and its no fun buying an item that is going to fail

so Um not to be stupid but will it work on my bike and should one get a new stator as a baseline
I assume a bad stator can take out a reg rect of course and maybe that is wrong.

[posplayr]

More than likely I will not be pursuing this design because as previously mentioned there are at least three manufacturer making them.

I called Cycle Electric

Cycle Electric

and checked with the engineer. The 80 V/5000 RPM = 16V/KRPM output of the Suzuki is very comparable to their series regulator design. The only problem is that the R/R is rated for 50 amps and it is large.

600 series are all the same size but with different mounting and connector options

Size is 4.75"x 3.4" x 1.5" (LxWxH). In the pics you
For comparison the Electrosport is about
3.5"x3.0"x1.25"

These units are available and are under $200 from dealers but not directly from Cycle Electric
This is the same unit. The mounting plate attaches to the R/R and may or may not be included in that price.

I have a line on a Compu-Fire unit which is also 3 phase Series and rated at 40 amps so it looks a little smaller and I found an E-bay dealer that is offering a better deal than you can find online anywhere (that I have seen). These guys are based in CA. Still waiting to hear back on the size

Also checking on at third one but not sure they will sell the R/R separately.

I'm getting one for $180 shipped from an outfit in IA, but they will drop ship to SB. If anybody is interested in a group buy he said he would drop $15 off the price for 10 people but with shipping I'm not sure it is worth the effort. I'm not going to organize a group buy, so if anyone else is interested I'll forward the contact info, maybe you can get him to come down a little more on price.



There have been a lot of development in high efficency AC to DC power conversion for all kinds of electronics devices. The key approach to reducing power is to get rid of the direct Full wave diode bridge (Like teh OE and Electrosport have). Typical drops are about 2 volts times what ever current is being supplied (say 15 amps so 2x15=30 watts). Shunt type regulator which shorts the phases makes that even worse.



The newer designs implement the diode bridge with Power MOSFET's which reduce the forward diode drops down to maybe 0.2V @15amps (0.2x15=3 watts) , so the power savings are significant. Unfortunately the FHA0012A type regulators are still SHUNT type and they short out the stator to reduce the power to the load. This is like dimming the lights in your house by shorting the wall outlet with two screwdrivers . The lights dim but you overload the house wiring unless you blow a fuse. SHUNT is very bad unless you are talking about small currents which we are not.



So a natural extension of full wave rectifiction with MOSFET's is to actually do series regulation all in the magic of timing the turn on turn off of the devices to acheive both rectifcation and regulation at the same time. Power dissappation drops significantly and the stator only has to supply that which is required for the load.



These devices can be made very robust in terms of voltage and current capacity with very low drop out. The are ideal for high output at minimum RPM.



Here is a brief overview of power switching. The final figure is what we have on the GS charging stator/rotor/Rectifier (regulator not shown). The low power timing circuitry is all that is missing.

So given the 40 amp capacity and small form factor of the Compu-fire device, I'm assuming this will be a very robust design and even exceeds all fo the original goals I set out for my design (save for a 6th wire). So this should be a direct bolt on for any GS to solve most of the shunting over heating issues and burning wire/connector issues (stator side at least).



If you look up the parts or are studying the different rotors/stator combinations, the Compu-fire 55402 is a general purpose 3 phase SERIES R/R that works with the 3 phase 18 pole aftermarket stator and rotors that Compu-fire make for HD's.



It should work on almost any metric bike as the current capacity is more than any stock OE and aftermarket designs. It should even work for 12 pole designs as long they are 3 phase (most all are)



I think we should end the poll, I'll start another thread after I get the device and do a comparision between FET Shunt and this device. I have a current clamp to put on the stator leads to see how it differs on the stator side and then estimate the HP savings.

[Steve]

Currently satisfied with my FET regulators, will see how they turn out.

Please continue development or whatever you choose, it would be nice to have an alternative if the FETs prove to have problems of their own.

Ssrr

I would get one of yours. Too bad there are replacements. But I still need to sell some GS Parts.

If you dont run in the 5K-7K RPM range for sustained periods( 30-45 min) the FET/HONDA/SHUNT R/R should be alright even if the stator is getting hotter and causing more load than needed. 20% higher output power for stator touted by Electrosport makes it worse

The Compu-Fire is a proven production design and apparently pretty current technology (last 5-10 years at least) as well. I really have no interest in becoming a power circuits engineer

Edit: I think the design is probably less than 2 years old as it us listed as part of thier new products.

[bwringer]

They still using a stator in those new fangled things??? Sheesh you'd think they can pony up the duckets to put alternators on the Busa and Gixxers they could have done the dual sport riders the same favor.

Well, the permanent magnet type inside the engine still works when the engine is partially underwater, and is pretty well isolated from gravel...

With this Series R/R the GS's PM stator should be more efficent than even an alternator. For the same power delivered:

• There is no heat loss is friction (no bearing and no brushes)
• No field windings to charge
• Less power loss in the rectifier diodes.

Would be interested in seeing a schematic for this if you have it.

I don't know if it's too late or if it will help, but here's a link to the stock HD regulator for $129
