RPM speed is 0-475 for the low gear and
no load for the DeWalts 960 18V. with a speed of 440 RPM and a load of 25
kgrs the motors operate at 92-93% and a loss of about 7-8%.
The speed on teh 9 cm-dia.-drive wheels, with the
load of 25 kgr, is 443 RPM. (7.500 ms : 60 : 0.09 m. : 3.1416) It sounds awfully
lot or I have almost no loss and teh torque is more than plenty. Joe said about
30 messages back that "Most of the time our tank motors operate at
about 75% of no-load speed which is close to maximum efficiency."
What is the RPM speed of the DeWalt 960's - 18V in teh low gear and no
load to find out my loss? I guess I should go find it.
