How elevators stop so precisely

You step out and the floor is almost perfectly level 👀 That tiny stop is controlled, not lucky.

First, sensors measure where the car is 📍 Encoders turn motion into digital signals, while lasers, reed switches, Hall sensors, or wire systems can mark floor position.

Then the control system slows it smoothly ⚙️ Encoders feed speed and position back to the controller, which adjusts travel and door motion for a controlled stop.

Final backup: safety systems step in 🛑 Motor brakes, governors, safeties, buffers, and redundant sensors are there if anything goes wrong. Save this for later 🔖
