PMDC motor as generator Characteristic

[manishanand14]

Hello Everyone!

I need the characteristic graphs for PMDC generator.

For example V[voltage generated] Vs N[speed] graph.

The gennerated voltage will be about 80 - 95 % of the motors ordinary characteristic. i.e. if a motor runs at 18,000 RPM at 12V, then at 18,000 it will generate 10V+
