Good afternoon everyone, first of all thank you for opening this topic.
I am looking for a motor to brake a shaft, that is to say that most of the time it will be turning in the opposite direction.
I would like to control the motor torque by means of a signal, and the torque would be to oppose resistance to the rotation since it will rotate in the opposite direction (generating).
The motor should be able to generate a torque of between 1 to 6 Nm of resistance with an rpm close to 20. And the size of the motor should be small, to fit in one hand at most.
I am writing in this forum and I would like advice to find a solution. I have thought of using “Dynamic Braking” through some kind of digital resistor but I don’t know if I can control the torque.
