The sizing of linear motors is mainly determined by the application-related characteristics of velocity and feed force. First, the user should determine the velocity and force profiles for the required application and set the proper parameters for payload, thrust force, ambient temperature, and axis tilt. Then the choice of motor size is made either by simply calculating the physical limits, or by using a motor sizing application.

One online application for motor sizing is provided at: Websmart

For example, enter an external payload of 1.2 kg and select the desired motor type (NL tubular linear motors). Then press the Motion Profile button.

There are different options for the motion profile type. The simplest is polynomial 5.

It is also possible to upload a cam profile file based on position points. Here is an example motion profile file: :cam_profile_example.zip

This example must contain, in the first row, the number of position points; in the second row, the time resolution; and then the position data points, with units in meters.

As an example, we selected the Polynomial 5 motion profile. The motor will move from 0 to 10 mm, with a cycle time of 0.2 s and a waiting time of 0.1 s. Press the Add segment button to update the motion cycle.

Then we move back 10 mm with different timing.

A summary window with all the application data is shown.
