@onedangt said in Torque of onewheel motors:
@notsure And yet another question, what amount of torque/power would it take so the board could totally prevent nosedives?
Good question and not too hard to approximate an answer. Leaning fwd a loooong way, your centre of gravity could be as much as 1m in front of the axle, so the motor would need to produce about 1,000N.m of torque to prevent you leaning further forward. Those are pretty big numbers and I suspect the tyre would just lose traction.
People quoting power as the be all of nose dives is misleading. Torque is what the rider feels as acceleration. Lets say my really rough numbers earlier are true and the little XR can produce 200N.m of torque. I'm putting a 144V 110kW electric motor into a car conversion and it only produces 220N.m of torque, but it does rev to 8,000rpm. The XR motor is a low speed high torque electric motor.
