Electric Actuator: Transportable Mass, Thrust, and Push Force of Electric Actuators
Transportable Mass
The transportable mass is the load mass that can be moved according to the specification of the electric actuator.
Values are set for each of the horizontal and vertical directions. These values are listed on the product detail page for each product name.
The load mass affects the relationship between positioning distance, positioning time, and acceleration in transportation.
In selecting electric actuators, it is necessary not only to confirm the transportable mass but also to confirm that they meet the operating conditions such as positioning distance.
Thrust
Thrust is the propulsive force with which an electric actuator can push the load forward. It is a force that acts against the load to be moved.
The upper limit values are listed on the product detail page for each product name.
For information on how to determine the thrust required for transportation according to the mechanism conditions, refer to the reference material on selection.
About the Upper Limit of Thrust
The upper limit of thrust is determined by the estimated life of the parts being driven (ball screw, guide, bearing, etc.).
The estimated life is calculated based on the dynamic load.
The electric actuator products have upper limit thrust settings to ensure stable transportation from low to high-speed ranges.
Push Force
Push force is the pressure applied when the electric actuator pushes against the load. It is a force that acts against the load that is at standstill.
The values are listed on the product detail page for each product name.
About the Upper Limit of Push Force
The upper limit of the push force is determined by the static load (basic static load rating) applied to the parts that support the load (ball screw, guide, bearing, etc.).
The stepper motors built in electric actuators provide particularly high torque at lower speeds.
