Hi Everyone - I compete at the top level in Stihl Timbersports/Lumberjack Sports competitions. One of our events is the hot saw where we are using 330cc Rotax or Honda CR motors tuned for racing. Here is a video https://youtu.be/G9DiMPGsH9U?t=12037
For a while now I've thought that going electric could be a game changer for a few reasons. There would be no warm-up or starting issues, there should be less vibration making for smoother operation, and the motor would reach top speed faster. Maintenance and reliability should be easier/better as well.
I'd like some guidance on electric motors and battery/power pack/supercapacitor configurations that would meet my needs.
Our 2 stroke motors crank out 50-60 horsepower, 50 lb of torque, and generate chain speed of 290 feet per second. The motor and exhaust weigh about 30 lbs. Are there any elecrtic motors out there that would have similar power and weight profiles?
A typical "racing cut" is 3 cuts on 16-20" softwood. Times are usually 5-9 seconds. Max run time would be 12 seconds on hard wood. What sort of battery/power pack/supercapacitor configuration would meet these power needs above and last 20 seconds or so? The less weight the better if i were to mount the power supply onto the saw, but I would also have the option of keeping the power supply separate from the motor/frame/bar unit and connecting it via cables. If I were to go this route, what sort of connections and cables would I need?
Any info you can relay me would be a good start. Thanks!
