I'm controlling 2 DC Motor's (link attached) using PWM. But, I noticed that when I'm smoothly reducing the speed of the motor and the duty cycle is approximately 25/30%, it stops moving.. I guess that's because the motor is not receiving enough voltage when I have a duty cycle inferior to 25/30% . However, can you tell me if the motor is already locked (duty cycle = 0) with a duty cycle between 1% and 25/30%, or it's just in neutral point (like the motor of a car when I don't shift into a gear)?
I'm asking this, because I want to use these motors to build a 'car', and if I want to turn right (for example) I'm reducing more quickly the speed of the motor on that side. If it lock's before it achieves DC=0%, the left motor will drag the right side of the car.. It would be important to know this, before I assemble the several parts.
Thanks in advanced!
