@TheAngusBurger An electric motor’s torque is independent of the rotation speed, so theoretically it should have full torque from zero to full speed. However, the real challenge here is the speed controller. The type of speed controller that we use, a sensorless brushless controller, doesn’t do a good job of operating the motor at high torque and low speed. Additionally it has a minimum speed of about 200-300 RPM.
We’ve been experimenting around with other types of speed controllers, mostly sensored controllers, to address this, but it’s challenging. What speed are you hoping to run at?
