Hello,
Complete newbie to electronics. I have mechanical engineering background but the memory of some electronics I learned in the past is quick to fade..
I have a sidecar rig (motorcycle and sidecar combination).
I built an electrical reverse gear for it.
Honda GL1500 motorcycle starter motor drives the sidecar wheel via friction wheel pushed against tire tread.
It kind of works but the friction wheel slips against tire tread and wears quickly.
Mechanical solutions will be to increase reduction ratio or to use different drive mechanism (e.g. chain/sprocket) but I am wondering if I can solve this electronically by reducing/modulating motor torque.
I googled and found MOSFET based PWM but no off-the-shelf controller (with reasonable price) for my application. I don't think I can design it by myself.
So I wonder what if I put a power resistor to reduce a voltage to the motor. I know this is very crude approach but will it worth a try?
I still need to figure out what resistance and wattage..
Could any one point me the right direction?
