DC motor parameter

[kesigan07]

is there any data sheet for DC motor SPG20-50k? i need to know its parameters for my PID control simulation. the description that provided here did not have resistance value, inductor value, viscous-friction coefficient and so on.

I don think the manufacturer of this motor tested those parameters. If you want those parameter, try search for high cost motor such as Maxon motor, there have most of the spec . But the price is not as cheap as SPG from Cytron.

Have you ask Cytron? I don think they can give because the factory that build these motor does provide that parameters.
