how must the mico motor powered

The 5119 Micromotor (2986 on Peeron, and 70823 in TLG) is used in the 8480 Space Shuttle set. From Brickfactory.info , here is a picture of it being used in the alternate (submarine) model. There is an old-style 2x2 electric plate attached to the 5306b "Electric, Wire with Brick 2 x 2 x 2/3 Pair" cable that clips onto the backside of the 9V Micromotor:

The micro motor has extremely low RPM and it can't handle heavy work because the pully knob pops off the motor very easily. There are many uses for this but not as a heavy crane or for moving vehicle.

I have 2 working motors both from 6979 (UFO series Interstellar Starfighter) along with the lighted parts.

Ah well my harvester uses two of them but the way i did it is not to have the micro moter direct to the shft.I used gears to link to the moter this stoping the popping off.

Very slow, much slower than the XL motor. According to http://www.philohome.com/motors/motorcomp.htm (great resourse!) the motor turns at 35 rpm, compared to 220 rpm of the XL motor.

Now I hate that the PF motors have any sort of gearing down inside them. I really want to do that myself which is why I often still use the old ungeared 9v motor. However the micro motor is the exception as about 1 turn every 2 seconds is actually a very appropriate speed for this motor considering.

On his Flickr photostream, The Scooter Guy posted these two pictures about "LEGO Micro Motors --- The transparent one seems to be very rare. Anyone have a transparent Micro Motor?"

This seems relevant:

Yeah, the clear one is a test mold. It didn't appear in any set.

I have 9 of these motors, of which 3 are broken. The unusual gear reduction mechanism it uses is very prone to locking up. It doesn't seem to be easy to fix it without damaging the motor casing.
