I have a DC motor that have datasheet.
This datasheet is contained all motor parameters, such as R, L, Kt, J, B, Ke, Fs...etc.
But, the motor is connected to a gear box and metal plate.
I have tried to derive its parameters that motor connect to a gear box and metal plate.
I assume the parameters, R, L,Kt, Ke are the same, but the parameters, J and B will be changed to J_load and B_load.
My derived result is as follow.
J_load is 200 times J.
B_load is 1600 times B.
Do you think it is reasonable in your sense?
Appreciate for your help.
