BACKGROUND: I am an intern with a local company. We have a powerful 60 KW Engine that runs throughout the day. We have a two Machineries that are powered off the Engine directly (using clutches and gears of cause).
The first Machinery runs a feed continuously, while the second Machinery is periodically engaged to cut strips of sheet metal (Cutter)
MODE OF OPERATION FOR THE SECOND MACHINE:
- The cutter is engaged to the engine;
- It spins at a very high speed
- cuts a strip briefly
- and disengaged
--> After it is disengaged, I've noticed the cutter spins for almost 40secs before coming to a halt.
--> I also estimated an initial Idling Torque 20 - 30 Nm ...@3000+ rpm (rough calculations from data I retrieved from as-built documents)
PROBLEM: We want to install a brake for the cutter; And am working with a staff on the brake design; ** I feel I can propose installation of a little Generator to utilize the free-spin energy. I believe this can act as a Soft brake. (using clutches still)
Obviously, only a small amount of current can be produced for a few seconds...
- I want to know if I can store electricity that is generated for a few
seconds repeatedly (non-constant intervals). If so how?
- I know quite a bit on Capacitors and Batteries, but is there any battery that can be charged under these conditions? ...I have done lots of fruitless Google searches
- Some staff have told me its a fruitle idea with no convincing reasons...(@least to me)
- Please give me further directions on what to read
NB: I am an Undergraduate Mechanical Engineering student
