VALUE OF PID CONTROLLER (KP,KI & KD)

[amir]

May i know the value of Kp,KI,Kd for these DC motor products:
1. DC Geared Motor with Encoder ,SPG30E-20K
2. DC Geared Motor with Encoder ,SPG30E-20K

Frankly, do you know what is KP, KI and KD?

PID values depend on your system, not the motor.

From these two products,DC Geared Motor with Encoder ,SPG30E-20K and SPG30E-20K ,may I know the physical parameters for both products :

Physical Parameter:
Ra: armature electric resistance (W)
La : armature electric inductance (H)
J: rotor’s moment of inertia (Nms2/rad)
b: damping ratio (Nms)
KT: torque constant (Nm/A)
Ke: back EMF constant (Nm/A)

Can you let me know what is the difference between motor no.1 and no.2?

Same for this:

Anyway, cannot help you on the parameters you need. Don't think low cost motor have these parameters. You should look for high end motor.

The motor manufacturer does not provide these parameters, not that they refuse to do so, but they do not perform test and calibration to obtain those data.
