ABSTRACT:
A method of selectively utilizing a set of linear actuator motors for an application includes providing a plurality of linear actuator motors numbered from 1 to N including a box shaped housing with respective lengths between a first end-plate and a second end-plate and respective hollow shafts. Each hollow shaft includes an extended portion out of either the first end-plate or the second end-plate and configured to receive a nut including a tube part integrally connected with a flat-end part. The nut is configured to be able to mate in a common manner to any of the plurality of linear actuator motors. The method further includes testing any of the plurality of linear actuator motors including the nut for the application, wherein the nut is detached from one linear actuator motor to reattach with another linear actuator motor.
