Coreless DC Motor

I managed to obtain 3 coreless DC motors. THese are supplied by
Premotec and are Part No 9904 120 13819. 30VDC nominal 100mNM speed
2540 but does have 50:1 gearbox fitted. Nominal current 1 amp. Torque
constant is 106 mNm/A and a terminal resistance of 8 Ohms. They seem
nice little hefty motors. The gearbox may be discarded if necessary
(or do I leave it fitted)

Are these suitable for driving my Eagle25 mill conversion ?
Can they be used with the Gecko 320 drive unit ?

Thanks

George
