Can I just say 'projection', or is there something better?

外来語っぽいですから、『リラクタ』の由来も教えて頂ければありがたいのです。宜しくお願いします。

Reluctor
Explanation:
パルサコイルはパルスジェネレータ(発電機)と呼ばれているセンサで、クランクシャフトに取り付けられているACGロータ(パルスロータ)が回転するとACGロータの外周にあるリラクタ(凸)部がパルサコイルの磁束を変化させ、パルス信号としてCDIユニットに送り、エンジン回転速度、クランク角度検出を行っている。
 進角制御は、次のように行われる。
・エンジンが回転すると、クランクシャフトに取り付いているACGロータも回転し、ACGロータのリラクタ部の角がパルサコイルのピックアップを横切る瞬間に2・351図に示すように正電圧パルスと負電圧パルスを発生させる。
・エンジン回転が上がると、パルスコイルから発生するパルス数と周波数の電圧が高くなる

Reluctor:
A gear-like part of an electronic ignition system, having the same number of teeth as there are cylinders, near the top of the distributor shaft so that as a tooth passes a pickup coil, resistance to magnetic flux is reduced and the magnetic field is strengthened, which triggers the electronic control unit.
