🛠️ Inside the N1 Speed Sensor
Ever wondered how the engine tracks its fan speed? The N1 Speed Sensor on this turbofan engine is the answer. Installed at the 5:00 position on fan frame strut No.6, it reads the rotational speed of the LP rotor using magnetic induction.
It has 3 independent sensing elements inside, each with a magnet, coil, and pole piece. As the 30-tooth sensor ring spins, it generates signals—one tooth is slightly thicker to give a phase reference signal for trim balancing.
These signals go straight to the EVMU and ECU for real-time engine monitoring. Precision, reliability, and aerospace-grade engineering at work. 🔧✈️
