I am making a huge line following robot and using arduino & sensor BLDC motor salvaged from Segway. The problem is that I am not able to control the motor properly. If the PWM signal is low the motor doesn't move, and if the PWM signal is slightly high then the motor goes at high speed. So I am not able to move the motor at slow speed which is giving problems.
Motor driver used: Kkmoon motor regulator
- Motor phase wire connected properly with driver
- Hall sensor wires not connected since it didn't make a difference in rotation when I was testing it.
Any solution to the above problem?
