Motor design

Good afternoon!

Today we will speak about Motor Design for our project.

A. Motor Type

In various types of motors, the axial gap structure is proven to be the most efficient way to construct a motor in limited axial space because the output torque depends on the space in the radial direction. Therefore, it is possible to obtain a high-output axial gap motor with a short axial length. In addition, the axial gap structure is suited to utilize AMM cores because it is difficult to connect AMMs to iron yokes due to their unique mechanical properties. Within the axial gap structure, there can be more than one working face from the combination of two rotors with one stator or one rotor with two stators. The combination of two rotors with one stator contributes to lower copper loss and conserves space in the axial direction. The combination of two stators with one rotor can lower the cost of magnets and yield lower iron losses on the back yoke. The number of poles and slots can be decided by taking into consideration the space for stator coils, the flux leakage from pole to a pole inside the rotor, and cogging torque.

First MATLAB Simulink model

Good day!

The second week passed through.
We’ve new information about MATLAB Simulink models.

For this time it’s better to see the presentation we made with all the models we found, let’s take a look at them

We discussed each of the models, and the first decision was to stop with the induction machine model, for now, to investigate it more detailed.

The second induction motor model has been chosen since it was from a trusted source – ADVANCED ELECTRIC DRIVES by NED MOHAN

First weekly sprint

Hello again!

Based on the results of the first week, we found the following information:
First, we found that we could use a synchronous motor as a generator, consider its advantages and disadvantages

HSPMTC advantages:
The main advantage of HSPMTCs is their minimal length of the winding end-turn and accordingly the minimum overall dimensions of the entire electric machine at the maximum energy density, in comparison with other types of electric machines. In addition, HSPMTC can effectively implement the technology of oil-free small gas turbine engines, which are particularly effective in aerospace engineering.

Distance working

Hello! Good news!

Due to the situation in the world, it was decided to continue participating in our program in the form of distance learning.
Now we have weekly meetings with our professors and professors from Ostfold University College.
The first step in the development of the project is:
Development of the MATLAB Simulink model to simulate the processes necessary for the operation of our system.
At the first meeting, we discussed where we can start developing and searching for the necessary information.

See you next time!

Traveling to Norway! (no)

There are not good updates.

In March, we were distracted from the main theme of the project, since we were getting ready to travel to Norway for the exchange program from March 20 to June 15-20.
But, unfortunately, for all known reasons, the borders of our countries were closed and we hung in anticipation of a resolution of the situation.
