Calculating the Parameters for an Asynchronous Motor

Hello,

I am working on 3D printing construction and my objective is to control the flow of the material so for that I need to control the motor. I am using Nord motor Asynchronous motor 100LA/4, and I am trying to calculate the different parameters of the motor like resistance inductance capacitance and motor constant. I have tried different equations to calculate but the simulation result is not good with those values so could you help me that how can I find the good values for these parameters?

Full load power = 5hp, 3.7kw.
full load speed = 1725 1/min
Mn = 20.5 NM
IN = 230v, 15.2 amp
rotor inertia = 0.006kg.m2

I will be grateful if you could help me. Thanks and awaiting for your response.

Regards,
Dipen Patel
 
All the FDM 3D printers that deposit melted plastic from a spool use a stepper motor that can be precisely controlled to advance the plastic material into the heated nozzle.
The slicing software will also add commands to retract the plastic to prevent strings between different locations on the part.

You can find stepper motors in a wide range of sizes and powers.

That diameter of plastic material do you plan on using?
The plastic filament common sizes are 1.75mm and 3mm.

Why would you need a 5 hp motor?
How BIG is the 3D printer you are designing?

good luck
 
Hello,

What do you want to control? Position or Velocity?

In this kind of situation, I would recommend to use Model-free controller approach. Which is a good approach when you don't know the model/parameters of your systems. I have design a simple one (GSJ: Volume 7, Issue 7, July 2019, Online: ISSN 2320-9186
SIMPLE AND EFFICIENT DESIGN OF A MODEL-FREE
CONTROLLER BASED ON LAG/LEAD COMPENSATOR), which was simulate with DC motor. I would like to try it in industrial environment.

The implementation is easy, it works in a closed loop, all you need is a lag controller.

Tell me if you are interested to try this MFCL, then I will guide you on its implementation.
