Model DC Motor: Torque, EMF, Resistance & Regulation

Click For Summary
To model a DC motor accurately, the moment of inertia (MMOI) and electromechanical time constant are essential, but they can be measured if not provided. Users can utilize various methods to determine the MMOI, such as direct measurement techniques involving the motor's physical properties. The discussion emphasizes the importance of these parameters for effective modeling and control of the motor's performance. Suggestions for measurement methods are encouraged to assist in obtaining the necessary data. Accurate modeling will enhance understanding of the motor's behavior and efficiency.

Hello, I want to model a DC motor which I bought from a company. I only have the following information:

torque constant [M.N.M./Amp],
EMF constant [MV/RAD/SEC],
Dynamic Resistance [OHMS] and
Motor Regulation [RPM./M.N.M.].

The company does not provide the moment of inertia nor elect/mech time constant. As far as I know, I need all these three pieces of information in order to model the motor. Am I right? Is there a way to do it without the missing information?

You should be able to measure the MMOI if you are willing to make some measurements.

Hi Dr.D, which method do you recommend?
 

Thread 'Electric power distribution from powerplant to homes'

I am trying to understand how transferring electric from the powerplant to my house is more effective using high voltage. The suggested explanation that the current is equal to the power supply divided by the voltage, and hence higher voltage leads to lower current and as a result to a lower power loss on the conductives is very confusing me. I know that the current is determined by the voltage and the resistance, and not by a power capability - which defines a limit to the allowable...
