Re: e-Power Challenge 2008 update

Hey Cal, It was good to have you join us at the races. Thanks for the photo and the movie clip was a surprise. Would you mind if I put them on my flickr site? Was that movie clip taken with your cell phone? Sorry, BIll. I over exposed the video of you a bit. http://home.comcast.net/~calinb/SANY0126....

Re: e-Power Challenge 2008 update

OK, I've had a full nights sleep. Let's see if I can put to words the results of the ePower Challenge. There were only about three weeks notice for the ePower Challenge. After trying for more than three years to get insurance for the ePower event, coverage was acquired mere weeks prior to the HPC (H...

Re: Do You run a Kill Switch?? if not? why not ?

I use a knife switch that is remotely operated to disengage the batteries from the motor. I have had a stuck full on throttle lately. The kill switch has been installed since the day I built the system. One never know when it might be needed.

Re: e-Power Challenge 2008 update

Here are the stats after today's open track. I only ran a 48v pack today. I'm going to race in e-Cat 1 Division 3 for twenty-four miles. e-Cat 1 Div 3 allows a maximum of 860Wh pack for Lead Acid. Edited at 10:10pm to include data for second test run. Reason for second run was that I shimmed my fron...

e-Power Challenge 2008 update

I'm stuck on the wrong side of the track. After all I did to prepare. I forgot to bring my battery chargers. So after my open track time I had to run the batteries home to charge. I couldn't leave them sitting all day the way they were. I rode 37.7 miles at an average speed of 30.4mph. My fastest sp...

Re: Atten: C'lyte Gurus. Help needed right away! Please.

Glad you got it figured out. Keep us posted on the racing. A couple of thoughts, though. You should be able to hold the motor at stall with just your hand. A 406 at 48v20a is not torquey at all, less so than your 408, and the controller will cut out after a second or two if it detects no change fro...

Re: C'lyte throttle stuck wide open---> cause?

It would have been nice to have a 405 or 404 in my 26" wheel . I have a 406 on a 20" wheel with 48volts of LIFEPO4 on my faired LWB bent bike, and max out at 43 km/h. I cannot see using a 404 would overcome the wind resistance or whatever is holding me back because the wheel spins freely at 49km/h(...

Re: C'lyte throttle stuck wide open---> cause?

I installed another throttle and the velomobile ran great with out a hiccup. Just got back from a 20mi ride and had plenty of juice left in the 48v AGM pack. When I get some open track time next weekend I'll be able to fully test the system. As it appears now I'll be able to run with the throttle at...

Re: Atten: C'lyte Gurus. Help needed right away! Please.

The velomobiles running now. It seems that I had a combination of minor problems. I had regeared the velomobile with a 60t chain ring and an 11-34t mega 7 freewheel. What I didn't do was add some length to my chain. When I was in the 60-34 combination I couldn't pedal do to the tautness of the chain...

C'lyte throttle stuck wide open---> cause?

Outside of the throttle assembly itself could a faulty motor controller cause a stuck wide open throttle. How likely would that be. I've got my system running for the e-Power Challenge. I had the velomobile up to 30mph and still accelerating slowly but ran out of street. Had to pull the emergency di...

Re: Atten: C'lyte Gurus. Help needed right away! Please.

You may have lost one of the hall sensor signals. If the axle was slipping, it would have ripped all the wires out. The motor might be OK, but check the hall signals as close to the controller as possible. You may have a bad connection or a broken wire. Can you measure the motor current when this i...

Way back when everything worked well on my 408 then one day the motor started to skip, hesitate, pulse, shudder, not work, start working ect. Thought it might be my motor. Now the same thing is happening on this 406. What is common it the motor controller, throttle, batteries and main cable harness....

Re: Crystalyte axle question

Well the axle transplant was a success, sort of. In the end it'll work out. The first axle pressed out of the 408 stator like a knife through warm butter. I took apart the two motors and into work I went with only the stators. Got plenty of help from the maintenance department. As I said the rear ax...

Re: Crystalyte axle question

I wouldn't have a prob trading the 405 that dual speed, or maybe loaning it. Too bad it isn't a straight 408 ... if it was we could just trade rotors ( I own a 20 ton hydraulic press ... heh ). What's to stop us from trading rotors? I hadn't thought of that. On my dual speed you don't have to have ...

Re: Crystalyte axle question

I live in the Portland area, and am getting ready to replace my 405 rear with a heinzemann hub. Would you like to borrow a 405 rear hub? It's on a 20" wheel. Or I might be talked into trading it for the 408. Yes! at the least I'd like to borrow it. On my 408 I've extended the cables several feet so...
