Hello,

I am working on electric vehicle simulation. I am using Motor & Drive(System Level) block from Physical library. I have the data of electric motor required and I am trying to simulate vehicle performance.

I have never used Motor & Drive (System Level) so this is my first time. My problem is that when I trying to simulate the model I am facing one problem. I have attached the screenshot of the data. I am not sure how to solve the problem. I have followed the rules of building the data as shown in Generic motor and drive with closed-loop torque control - MATLAB - MathWorks India.

I cant upload the whole model but I am attching the relevant data in mat file for the motor for reference and the motor how I am working on it.

And I also wanted to ask if anyone have idea on how to calculate PowerLoss of motor. Currently I am using Pl = (2*pi*N*T/60)*(1 - e/100) correct me if I am wrong. I dont have voltage and current data.

Kindly share the solutions to this problem.

Thanks in Advance

Hi Jay,

Thanks for your questions.

There are a couple of issues in your attached model.

The Motor & Drive block must be connected to a DC source. In your model they are shorted together.
The Motor & Drive block only takes in row vectors. You can transpose all the column vectors in MATLAB workspace, or do it in the block's parameter fields, such as below:
