What are Intelligent Elevator Drives?

Construction Tech Review | Sunday, January 17, 2021

The advent of intelligent automation in elevator drives is more of a revolutionary leap than an evolutionary stage.

Fremont, CA: The elevator has been around for a long time, and while its essential function has remained stable, the technologies behind functional elevators have undergone numerous revolutions over the years. Future versions are virtually always better than prior versions, as is the nature of technology itself, even if it takes a few errors in between to get there.

Variable frequency drives (VFDs) are motor controllers that can change the particular frequencies and voltages operating the electric motor in response to changing conditions. This ensures optimal energy efficiency while also increasing the motor's average lifespan.

If the elevator is an automated mechanism, as it is in most modern buildings, the drive is the mechanical brain of that machine. These variable frequency drives run and control the elevator's velocity, motion, movement, torque, and other parameters. The most recent artificially intelligent elevator drives, on the other hand, include significantly more advanced features than this basic introduction to elevator drives might imply.

What are  Intelligent Elevator Drives?

Elevator drives were already automated before machine learning algorithms were deployed, but the outcomes are, as previously stated, highly revolutionary. To understand the improvements, consider everything that has been said about VFDs allowing anyone to program and control the aspects of elevator movement, and then imagine an elevator that can go beyond the generic programming to further enhance the energy efficiency, passenger safety, and equipment longevity in real-time. The latest elevator drives, when outfitted with the appropriate sensors, can not only modify to better suit the scenario; they can also learn from previous experiences.
