Motor Generators

I understand that quantity, power, speed or voltage can be expressed in joules. The question is, why does an engineer involved in design need this? The flywheel also has a corresponding measurement system. But why? Is work as a physical parameter also a unit of measurement in joules? For pricing? I showed everything with links in a post that was blocked. So somehow it's not even interesting.

" joules. The question is, why does an engineer involved in design need this?"

Most power equipment is rated in terms of power and energy. To utilize such equipments, the users are very interested in the energy. After all, that's what they purchase from the utility company to run the equipment, $/kWh. It's world wide standard.

Directly related, first you need to correctly calculate physical phenomena and understand these phenomena correctly. An engineer is a concept, a calculation, a drawing and an implementation. By the way, what is the difference between the operation of a galvanic battery accumulator and a capacitor under load? In physics, there are also concepts such as momentum and angular momentum. How are these concepts interpreted in electrodynamics and mechanics?

They sell quantity, but consume quantity over time. This is interesting for both the seller and the buyer. But creation is power, speed, distance, momentum and torque.

In my publicly available article I briefly outlined all the conditions: FLYWHEEL FOR OVERUNITY SYSTEMS (or the video is even shorter)
