Digital encoders are used in a multitude of applications, including elevators. One of the key applications of these encoders lies in shaft copying. What exactly is shaft copying, and what is the role of digital encoders in these particular features? This blog explores these questions in detail.
What Is Shaft Copying In Elevators?
Shaft copying is a form of digital feature that enables one to know the exact position of the elevator car within a shaft. Apart from knowing its exact position, shaft copying also covers features such as precise braking, so that the car stops at the right floor. Similarly, it ensures that the car stops at the right spot without sudden jerks and operates smoothly.
How Digital Encoders Help In Shaft Copying?
Whether a rotary encoder or a linear encoder, they aid in shaft copying in the following way:
1. Measuring The Motor
The elevator car in the shaft is either connected to a motor or to a pulley. The encoder is connected to this motor or pulley, thereby tracking the movement of the elevator car.
2. Converting Data
The mechanical data of the motor or pulley is converted into digital signals by the rotary or linear encoder. This digital data is then sent to the control system of the elevator.
3. Control System Monitoring
Based on the data provided by the encoders and the desired positions of the elevator car, the control system is able to monitor the motion of the car in real-time.
4. Implementation
Lastly, to ensure that the elevator car stops at the desired spot, the control system sends the signal to stop or slow the motor accordingly.
