    Motor Analysis Sotfware

    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...

    Electric Snow Blower (Gravely)

    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...

    Electric Snow Blower (Gravely)

    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...

    What got you into electric?

    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...

    New 2017 updates to ebikes.ca motor simulator to try out

    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)

    New 2017 updates to ebikes.ca motor simulator to try out

    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...

    Post your DRAG RACE ebike run !!

    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...

    Throttle pulsing when light is plugged in to CA

    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 :-)

    45% efficient F1 ICE engine ?

    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

    45% efficient F1 ICE engine ?

    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...

    Throttle pulsing when light is plugged in to CA

    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.

    Ultralightweight 50kW drag racing motorcycle project

    About wheelly bar, why not adjust/program the max torque output to be just right ? This way you get max acceleration. Just nail the accelerator and wait.

    'D-Drive' - CVT utilising toothed gears only

    Toyota prius does that with it's 2 motors and engine When you go to basics, It's a common differential, just setup differently.

    Displacement factor of Hub motor

    The power factor varies with load. I think that you will have to model the motor you can use emetor.com You will be able to see an estimation of it when you use sinusoidal current I would use 60% worst case scenario so you have to beef things by 1.66 x Maybe Justin from ebikes.ca can help here

    Rc Twin Mid Drive

    My reduction is lasercut and I welded bracket to the frame 100$ I think that you would have to do something similar to lightningrod. The drive, is not that cheap but is really small, 150$ Motor is 75 $ Maybe 300$ worth of bearings, pulleys, shaft and belts. Plus bolts, nuts and wiring. maybe...

    Rc Twin Mid Drive

    I am running SK3 6374 149kv. you can go with 162 or 192 kv. There is enough torque for that. Acceleration may suffer. I am contemplating 192kv but I cant recommend it since I dont have experience with this setup. They run great on VESC and 12S I top out at 80A phase current before running...

    Rc Twin Mid Drive

    The space between cell is to ''shape'' the pack to fit inside the bag. It was too high and I had some lenght left so by spacing them I was able to reduce high at the expense of lenght. A side benefit help cooling. But maybe I dont need cooling since I draw a fraction of what those cell are...
