Stepper motor question

We are buying some of the equipment needed and we have some dudes about the stepper motor.
The one specified at the bottom would work or do we need a stepper with more torque power?
Thanks everybody

Stepper Motor: Bipolar, 200 Steps/Rev, 42×38mm, 2.8V, 1.7 A/Phase
This NEMA 17-size hybrid bipolar stepping motor has a 1.8° step angle (200 steps/revolution). Each phase draws 1.7 A at 2.8 V, allowing for a holding torque of 3.7 kg-cm (51 oz-in).

The Stepper motors is for a satnogs rotator?
If yes, then according to specifications in wiki and to the available size in rotator,

the proposed stepper motor is right.
