How does a ball screw motor work

WebFor a ball screw actuator, its efficiency will determine whether there is a need for holding brakes. The efficiency of an actuator is found by dividing mechanical power produced by electrical power. The resulting answer is its efficiency rating as a percentage. Actuator Life There are various factors that affect the life of an actuator.
