Thats what you were saying, I remember now.

Looking forward to it Wojtek, be safe!wojtek said:OK i tested the top speed using my GPS
39-42kmh at 46.5v depending on how flat the road was...
44-45kmh at over 49v
but i dont trust GPS - would like to verify on normal bike computer.
tomorrow videos of starting uphill at 23%the webcam batteries are charging as we speak

tyres: schwalbe marathon front / odyssey dirt path rear so not really least rolling resistance! + it is a full suspension trike.

top speed - i will go check now but i assume around 45kmh - will confirm in 1-2h ok?![]()
just need to install the GPS as the f**** xlyte released the sensorless controller that does not quite work with CA but their own solution is not ready yet!!!

I hope the result are goin to be good! I thought their APM-Display has speedometer??
The Mighty Volt said:wojtek said:i understand your point. But as someone said correctly HS/HT are great motors to be run at under 2000W. More than that might be too much for it.
Re the cable thing - yes it sucks! But there is quite easy solution for it. Sensorless - no issue for me. I run it on my scorpion fs, on road / off road. LITTLE movement is enough to engage motor. Anyway who wants to start a bike on a motor alone? The only real problem is starting on very steepy hill. But how many times you will have a situation like that? If many times, then the sensorless is not for you.
Yes i did criticize this motor and crystalyte for many things around this new motor on this forum, but now i have been actually using it and the results are very positive for someone looking for a low power motor up to 2000W / 40-50kmh.
Hi Wojtek, I agree with you....but isn't this what 9C was created for?? The other thing about the 9C is that it has been out for longer and seems to have a greater variety of windings. I spoke to IceCube578 last night {much kudos to him} and he mentioned that there was some sort of choice in that department with the HT/HS. However, I still feel the 9C has the track-record. We have a ton of practical data on them. Now maybe when all the teething issues are knocked out of the new HT/HS range, they will be better, but the 9C offers that sort of performance right now and with far fewer of the performance issues. I'm not saying I would never buy one, but....not right now.

Thanks for the info guys!Andje said:I saw excellent performance all the way up to 5kw at 100v. IMHO you would need to rewind it with thicker wire to reliably carry higher current then that. I am looking into companies that do rewinds in Ottawa, and i'll post if i find something cheap.
I put fans in my X5 and it made a very huge difference. I can ride at 5-15kw for 1kwh and not over heat it!deVries said:Spacey said:That is pretty high power though, I've dropped mine down to 2,000 watts and it still gets pretty hot at the end of 12 mile journey. 66V 30ampThanks for the info guys!Andje said:I saw excellent performance all the way up to 5kw at 100v.

Have either of you tried any cooling mods? I wonder what one could do safely volts/amps with cooling vents? Also, what could be done with cooling holes & fan(s) too. I know several of these motors have already been modded with cooling holes/vents, and probably a few with fans too.
Any ideas, comments, opinions, or experience?![]()
Yup I used a ice cream bucket and cut it up and used it to make a duct to direct the air to the windings. And I have some cheep 12 volt fans run 4 in series to a 100v supply so they run at 25 volts each. Moving any air with a fan will help big time the holes in the sides of the motor dont help much on their own.Andje said:i drilled cooling holes in mine but no fans. It's a good idea though, and i read about it working pretty well in practice right arlo? no problems with clearance as long as you stick em in there right?

Yes, I've been reading many posts in that cooling the X5 thread. :wink:Arlo1 said:I put fans in my X5 and it made a very huge difference. I can ride at 5-15kw for 1kwh and not over heat it!
Uhm its there someware.... I think the number was ~ 160 degC for a ride in 8 deg wet weather and then cooled off the motor then tried the fans and was ~70 degC both the same run and both with a charged battery. I am working on a ducted fan system now.deVries said:Yes, I've been reading many posts in that cooling the X5 thread. :wink:Arlo1 said:I put fans in my X5 and it made a very huge difference.

Did you document your cooling technique with video or pics? I'd love to see the mods you did for cooling. 8)
No its not heavy.... Its 10lb lighter then a X5304!Tincan said:My HT3525 turned up today.

hi Spacey,
what controller are you using? Lyen sensorless? what speed do you get at 2000W constant?
I noticed that my xlyte 48v 40a controller is getting hot much quicker than the motor. At least in touch... I am also planning to change from 44v to 66v but will prob modify the motor first - make holes in covers and put some fans to blow air inside as lowracer did.
