An AC Electric Engine

The AC Electric Engine produces power by demagnetizing a Shaft Core which has been charged in a Magnetizing Unit. It requires an alternating redstone signal to run.

Rotarycraft Handbook Description[]

"The alternating current (AC) engine, like its DC cousin, requires a redstone signal to perform.  Moreover, this one needs an alternating signal, best supplied with a redstone clock.  Faster cycle times correlate to more consistent power output, with 2-clocks providing a constant supply of 512 Nm at 256 rad/s, or 131.072 kW.  This engine requires a magnetized shaft core, which it will gradually de-magnetize."

Usage[]

Each microtesla of magnetization of the shaft core lasts for 30 seconds.

Tips & Tricks[]

  • Redstone clocks from nearly all mods are ineffective or completely useless for running this engine, as they tend to be very slow.
  • The Sequencer from RFTools is a rare exception to the above: Place the sequencer with the orange arrow pointed to the engine, Select every other square on its pattern UI, and set it to "Loop1" mode. This will make it toggle on and off every tick, running the engine at full speed. Using redstone or redstone wires from various mods, a single Sequencer can run any number of AC engines and Magnetizing Units at once. It can also be less likely to introduce lag to your base compared to a vanilla redstone clock, as it does not require your Minecraft client to re-render lighting as it alternates.
  • Holding a magnetized shaft core near one of these engines will cause it to emit a small amount of power, due to the fact that moving magnetic fields generate a current. This takes precedence over normal functioning; holding one near an operating engine will make it behave erratically.
  • If you use too slow of a redstone clock, the output may fluctuate slightly from 129kW to 131kW.  This can cause issues using these engines with shaft junctions. Use a shaft power bus setup instead to split power from AC engines, or flywheels to stabilize the output.
  • Like it's weaker cousin the DC Electric Engine, the AC Electric Engine is a form of perpetual motion machine. Provided an initial energy input (a shaft core with a single mT of magnetization), an AC engine can run a magnetizer to magnetize a new shaft core to a higher magnetization. With certain automation, a closed loop system is achieved, creating new energy with no input material.
