Spintronic Inductor (55 H)

Once you get this spinning, the momentum is incredible—it keeps going for way longer than I expected. The weight gives it a satisfying heft that just feels solid. Definitely worth the extra effort to get it started.

Wasn't ready for how much effort it takes to spin this thing up, but that's the whole point. Once it's moving, it just keeps going, and the momentum holds way longer than I expected from a 55 H part.

Mounted this on my test rig expecting the usual spin-up lag, but the momentum it holds once it's going is genuinely impressive. It's heavy enough that you feel the energy going in, yet it just keeps coasting with barely any input after that.
