Synchronous motor…

Where did we leave off? Synchronous motor? Yes. Let’s continue.
The first problem connecting the synchronous motor to the system was the connection problem. The height of the engines was different, and the mounts were not perfectly even, which caused a lot of vibrations, leading to bad consequences, so it was necessary to fix it.
The first solution was to put a rubber gasket between the engines. But this decision died at the testing stage, the engines began to jump in a wave way, because rubber did not absorb vibrations, but only extended them.

Regenerative Braking

Stop… start… stop… start. If you make a habit of driving in city traffic, you’ll know it can be a huge waste of time. What’s less obvious is that it’s also a waste of energy. Getting a car moving needs a big input of power, and every time you hit the brakes all the energy you’ve built up disappears again, wasted in the brake pads as heat. Wouldn’t it be good if you could store this energy somehow and reuse it next time you started to accelerate? That’s the basic concept of regenerative brakes, which are widely used in electric trains and the latest electric cars. Why did we mention this topic? It’s because we see our system usage as regenerative braking, why not!

First steps

It all started with the formulation of the first task.
The goal was not quite easy, and we had to start with something not difficult, but at the same time important for achieving the final result.
We decided that if we want the engine to run at maximum speed, then we should try to accelerate a conventional asynchronous motor to unusual speeds and see how it will behave. In the photo, you can see our experimental sample.

How did we start?!

Hello! And welcome to our project!

In November of 2019, we (you can read about us on the corresponding page) have applied to the Ostfold University College exchange program. The wait for the results was exciting and long, but in the end, we won the competition and were successfully accepted into the project.

The main topic of the project under development was: to develop a high-speed asynchronous motor capable of rotating at speeds up to 150,000 rpm and also to work in generator mode, while it should be relatively powerful and small in size.

And already in January 2020, we began the first steps towards the development of the project. The most difficult thing was to start work on the project and correctly prioritize first tasks, but about them a bit later!
