Servo torque

<< < (3/3)

Hi, thanks for the replies.

Another question:

If I control the motor speed using PWM, when reducing the speed will the torque also decrease?

Torque in an electric motor is a function of how much current you can drive into it. The good thing with PWM is that it can use a high voltage for the times it is on, and thus have higher torque available even at slow speeds than a voltage-based alternative. However, at some level, you have to reduce the torque output to run slower, because a higher torque will cause acceleration up to equilibrium.
