Linear Actuator Selection

The actuator selected from the Rockwell website was the MPAI-B5450.

The fixture parameters were entered in the motion analyzer in order to verify we are using the appropriate motor. The results verified that we did in fact select the correct motor to use for this system. Several options were provided with the 5450 being one of the most reliable.

The points on the graph below show that our results are well within the tolerable range of the actuator.

Details of the performance under our system conditions can be seen here:


The software used for the selected PLC uses a concept called Ladder Logic. Ladder logic is a horizontal programming language. Visually, inputs are lined up vertically on one side and outputs are lined up vertically opposite them. The inputs and outputs are “horizontally” connected to each other, in a manner that loosely resembles a ladder. The horizontal connections contain sequential control logic (AND, OR, NOT, ect.). In order for power to travel to a specific output multiple conditions must be met. These conditions are determined by the program that is written and rely on input conditions as well as the circuit logic in the “rungs” that connect one side of the ladder (inputs) to the other (outputs).

A very simple example of the ladder logic for a light connected to a switch is:

More research must be done over the intersession in order to develop a successful program. Some links that we found helpful to start learning the basics were:
