Digital encoders are quite diverse in terms of functionality. While optical linear encoders serve to measure linear movement, rotary encoders are best suited for measuring the speed and position of a rotational movement. Used in robotics and manufacturing, these shaft encoders are also used in elevators. But how do these encoders serve this particular application? This blog addresses these uses in detail.
Major Applications Of Rotary Encoders In Elevators
Elevator Position And Speed Monitoring
The primary application of the shaft encoder is to measure the position and speed of the elevator at any given point. The encoders achieve this by measuring the rotation and speed of the motor shaft, as the rotary encoders are mounted to the elevator motor.
Accurate Elevator Positioning
The data provided by the rotary encoders is then used by the control system to ensure that the elevator cab stops at exactly the right position, as even the smallest overshooting or undershooting can be problematic.
Smooth Operation
By knowing all parameters such as position, speed, rate of acceleration and consequent deceleration, the elevator can operate as smoothly as possible, apart from being accurate to ensure comfort for the passengers.
Ensuring Safety
There is also an element of safety connected with precise position control of the elevator. This essentially prevents tripping when embarking or disembarking from the elevator. Similarly, it also allows the doors to open and close properly, adding another element of safety to the entire operation.
System Monitoring And Maintenance
The precise data gathered from the encoder can be further used to judge the life and quality of the motor and other constituent parts. This allows for preventative maintenance to keep downtime to a minimum.
