in need of a servo motor - slow working speeds
in need of a servo motor - slow working speeds
(OP)
Hi,
I am in need of a servo motor + controler that will run at really low speeds - 0.001 rpm. It needs to run smoothly, what kind of motor should I get, DC,AC? Manufacturer? It doesn't have to be all that powerful (about 120w, which is roughly 3nm in torque).

If you use a typical 200 step/rev stepper motor with a 256 microsteps per step drive, you will still need less than one increment per second at these speeds. When you look at the motion in the second timeframe, it will not be smooth. Over hours, it will be smooth. What do you really need?

Normally a gearbox is used on motors to get these very low speeds. Why is that not possible here?

Stepper motors do not vibrate and with microstepping there is the possibility to run the motors quite slowly. With 10.000 Increments per revolution the given velocity of 0,001 rpm means 10 Increments/minute.
