brushed motor specifications

Hi,

Anyone know where I can get specifications for stock speed 180/200/300 motors?

What I need are the physical dimensions, RPM, and electrical specs.

Thanks,

Dean

Electrical specs are in Motocalc generally and are PRETTY accurate. Those include RPM of course, unless you mean max safe RPM in which case take about 35K for a 300 rising to about 45K for a 180.

Motocalc has a decent figure for weight, too.

Here's a bit more..

I can't find the GRAUPNER SPEED 300 7,2 volts specifications.....In the table I read the datas for the SPEED 300 6 v. only.

Is the "Current @ Max Effic." the same for the SPEED 300 7,2 and SPEED 300 6v ??

Grazie mille!!

Kv 1775
Io 240mA
Rm 0.89 ohms

Max eff current is probably quite low..the 300 7.2v is a good direct drive motor, but for geared use use the 6v one.
