Abstract:
We are making a elevator model to overcome accuracy and efficiency in the past elevator model.
Previously if elevator car moves from one floor to other, then the speed would remain the same
throughout from source to destination which use to result in the sensing of jerk which was very
annoying and harmful to devices (to tension rope, etc.).
To achieve speed control of motor and smooth flow, we are using variable supply and frequency
(VFD) by which the speed of motor is gradually varied according to kind of operation. Different
sensors are also used to sense the velocity, load and position of elevator car.
A controller is also used to ensure safety, VFD is also controlled through controller, it operates
according to the commands from the controller (like transit time, max speed, etc.)
