How does the electric elevator operate?

An electric elevator operates using a system of cables, pulleys, and a motor. The motor, typically located at the top of the elevator shaft, drives a sheave (a pulley) that moves the elevator car vertically by winding or unwinding the cables attached to the car. When the motor runs in one direction, the elevator ascends, and when it runs in the opposite direction, the elevator descends. Safety mechanisms, such as brakes and limit switches, ensure the elevator operates safely and stops at designated floors.
