    What you can do to get two motors paired on the same axle is to mount them on the axle and brackets with some adjustment range, then align the motors by energising the same set of phases in the same direction with a dc current. It will move the motors to the same alignment. Then tighten your...

    for the specs it could handle that no problem. my next consern is the chain "Bends" allot of times in this setup what causes heat in the chain. and there so shorting its life time i guess... so maybe a oil bath would work better of 2 seprate 420/520 motorcycle chains to reduce "bends"

    i have the older version where you dont need the expensive software for. but i do know Sevcon software is not software where you just go on and change some parameters and it all works. it is a very very complicated device. and has endless possibility's with a good programmer. but i will...

    yes the are Sevcons size 6 gen 4. but with zero software. not sure if it is smart to start with a new program. (i also think you cant just go into the sevcon without a licence) i do have the old xiatt to program size 4 gen 4 Sevcons for the scooter of my brother (govecs) but thats a "normal"...

    back to school. first days are done with the exam's but new problems for the project accor. how do i get the Sevcons to work together? i wanted to split the throttle wire and send the same signal to both controllers. but this throttle has 8 wires.. and not the usual 3/4 wires. i am guessing...

    and we are back on the build. i made a jig to hold the front A-arm on the desired place so i could make mounts to hold them. the laser cutter a school helped my out, that was the last day school was open after that it was closed due to vacation. rear end assembled, the shocks are from a ktm...

    update: the frame is close to being finished! for the front A-arm i wasn't going to build a new set of arms. due to lack of time and to much complexity. The front arms, and hubs are from a Yamaha Raptor 700R. the upper arms are aluminum. if they brake i will replace them with chromo tube...

    good question: now the motors are on the same "plane/level" so a twin chain setup would be difficult. but maybe that will be a nice upgrade, because i'am doubting if the single chain is capable off the bends at the max rotation speeds. there i quite some heat getting in there :confused: the...

    update, wheels are bored out to the new diameter, and the holles are redrilled. ready to be installed chassis adapting wheels first mocked up. first chromolybdeem tubes came in (32x2mm), pre-bend due to stiffness off the tube. first suspension parts turned, nylon bushings and Ktm smcr...

    Here a small update on my corona project that i did in between: a Electric driftrike getting the steering colum shorter, so i can reach it from the seat position also added a 3th battery for better pressure on the front wheel so i get better traction. my brother went to a go-kart track...

    i did look at can-am/honda side by side diffrentials but most are designed with cvt system system so linear torque curve and not max torque at 0 rpm. and what i have seen/read a lot of tunners swap out the diffs for aftermaket diffs. because the aren't super strong. :roll:

    how do you mean? if you put 2 motors together the encoder doesn't "line up" to the other motor... it isnt a dc brushed motor. (no offence) if otherwise possible i would like to know how. but you can let a sevcon controller "slave" an extra controller. so they work together, thats the next...

    streetlegal crosskart/buggy build 140hp

    because the motor spins to fast to directly put wheels on it (needs a reduction off +-4:1). so it would need 2 chain drives to axles. and because 2 now the 2 motors work together and there wont be a diffrence in wheel speeds.
