Thank you very much !

I received my CL350. Unfortunately the 3shul motors site is down for maintenance, Is someone have the pinout. Unfortunately, I did not downloaded the manual before. Thanks

Hi, I am currently designing a motor and since Emetor is down I am wondering if there is anything simpler than FEMM that can be used. Motoranalysis does not compile on my computer even after adding proper matlab runtime. Just a simple static magnetic cicuit would be a good start. Thanks for...

Hi I can cut 34" wide by 18" high I can use it for 1h of course the duty cycle is not 100% maybe 50%. Motor is sold for 7kw but can do 16kw peak. I do 10kw peak wich is plenty. The way its mounted, the transmission case act as a huge heat sink. Its only warm after 1h of hard work. This winter...

Thanks for kind comments

Hi Guys, Just wanted to share some build pictures and a video of my 1972 2 wheel tractor conversion. The motor is a Heinzman PMS-126 that I bought here a couple years ago. Sevcon Gen4 size 6 drive is overkill but this is what I had on hand. I use my bike battery that is 24S11P li-ion of LG HG2...

I was flying RC helicopters electric started being ''affordable'' and powerful enough to convert to electric. What an improvement ! 1- No vibrations 2- A lot simpler 3- Way less maintenance 4- Quieter 5- More powerful 6- More reliable If it does the same for cars, ice cars are more than in...

You can add A+B ? This way a 2wd system can be analysed Thanks for taking time to educate me (I did not take time to do thorough tough about the whole system)

Just to be sure, can you confirm 1kv x 2V x 1A = 2kv x 1V x 2A This way we keep the same rpm and same torque It's just the the kv adjustment is limited and wish to experiment a hub as mid drive maybe wind it with 1T instead of 5T but gear it inversly I can generate then 5x the power knowing...

Félicitations ! You know that but I feel compelled to tell anyway : Drag race is all about the start, dont go too far with gearing. Did you experiment with field weakening ? Maybe it can allow you to keep high ratio gearing( belt) and still gain speed at the end. But chances are that you...

Thanks for the tip on speed sensor ! It's funny I just repositionned it yesterday thinking that it could be that. You just confirmed it :-)

Can you post the independent test for the 2016 prius drivetrain ? Would be interesting to read. my Insight is over 30% eff I agree that a fossile burning motor is outdated Thanks

They claim 45% efficiency and 50% with energy recovery systems Toyota Prius engine claim 40% thermal efficiency. Seem plausible to me. this is a 12.5% improvment, it's a lot but not impossible. also it's within Otto cycle theorical max thermal efficiency. Mercedes certainly wont substanciate...

I have the same problem but without light or other device other than throttle, battery, speed sensor and shunt. When speed goes aywire, the throlttle output shut down. and I get 647km/h ou whatever impossible max speed.
