Hi all

I took this off the graupner website as I don't have a meter thingy, and it seems to have all the specs on it:

SPEED Torque motors
Special high-performance motors with integral
suppressors. Characteristic high torque at low rotational speeds, therefore ideal for use in direct-drive model boat power systems with large
propellers.

Specification
Nominal voltage 12 V
Operating voltage range 6 ... 40 V
No-load rpm 6500 min–1
No-load current drain 1,1 A
Current drain at max. efficiency 8 A
Current drain when stalled 54 A
Max. efficiency without gearbox 71 %
Length of case, excl. shaft 85 mm
Diameter 51,5 mm
Free shaft length 15 mm
Shaft diameter 6 mm
Weight 645 g
