The motor in the 8735 pack (known individually as the 5225) is a much newer
design that includes some built-in gear reduction and a flywheel. It has a
fairly low speed, but high torque.

The motor in the 8720 pack (known individually as the 5114) is the older
design with no internal gearing etc. and consequently runs at a much higher
speed and lower torque.

From the RoboLab Guide...

Motor type          Approx power        Operating limit
                    Consumption

5225 (no load)         10mA                 350 RPM
5225 (normal load)    100mA                 250 RPM

5114 (no load)         40mA                4200 RPM
5114 (normal load)    160mA                2600 RPM
