151 Posted December 5, 2016 Report Share Posted December 5, 2016 Hi, I am using the motor from a Oset 20R for a project bike (started as a kart but after getting the motor it is too perfect for the bike project). I need to reverse the rotation of the shaft, which is easy enough but throws off the timing. Does anyone have info about timing these motors? Thanks Quote Link to comment Share on other sites More sharing options...

gwhy Posted December 5, 2016 Report Share Posted December 5, 2016 (edited) I would measure the current at a fixed voltage ( not through the controller but just a fixed 24v ) with the motor running in the timed (default) direction, then just time it to the same current in the opposite direction , then you should be good to go. edit: or use a tachco and time it for the exact same speed at the exact same voltage ( just the motor... no load ).

collyolly Posted December 5, 2016 Report Share Posted December 5, 2016 Is the motor designed to run in both directions ? I am not sure all D.C. motors are. Quote Link to comment Share on other sites More sharing options...
gwhy Posted December 5, 2016 Report Share Posted December 5, 2016 Is the motor designed to run in both directions ? I am not sure all D.C. motors are. its just the timing that determins the direction .. if the current/speed is identical in both directions then it has neutral timing but most are optimised for a spesific direction . I beleive that the timing can be adjusted on the oset motors, just not sure how easy it is to do with the oset brushed motors. Quote Link to comment Share on other sites More sharing options...
