Which stepper motors?

[Soranne]

Hello everyone,

I'm quite new to the world of CNC and I started to create my own one out of MBF, Nom I'm starting to work on the electronic part and I don't really know which motors to choose. I choosed this design : Mobile Gantry, stationary bed
and I plan to have one motor for each of the 3 axis. My CNC is not too big, it has a 30cm by 30cm bed.

I found this motor :

Step motor 56 steps - 4.64 ohm - 7V
6.50 EUR TTC
- type 17PM/H302/P1 Bipolar 2 phases
- 1,2 A / 7 V (for each phase)
- Dimensions: 42 x 42 x 40 mm
- Rdc= 3,64 Ohms

Do you think they are ok?

Thank you very much!
