VisualSizer Axis Design

The first step in the motor sizing process is to define the mechanical components to be used and to enter the appropriate data. The data as entered will enable VisualSizer™ to calculate the inertia and torque requirements.

There are certain sections in the window that are being used for the axis setup. We will explain their function in detail when we get to the sample setup as described below.

In the following we will set up a motion axis that contains of a motor, a gearbox, and a leadscrew. The motor is included in the setup per default. At this time there is no need to enter any motor data (even though that is possible), since VisualSizer™will access a motor database containing more than 1000 motor/drive combinations. Out of these 1000+ motors VisualSizer™will select the motor that best meets the speed, inertia, and torque requirements.

Step #1: Adding a Gearbox

In the 'Mechanism Selection' area select the gearbox by clicking on it.

Click on the 'Append' command button.

Note that the 'Visual Axis Setup' is being updated, i.e. the gearbox is being attached to the motor.

Enter the data in the mechanism data entry table as shown in our example.

Naturally, you may enter/modify the data to your liking, but for a first run we recommend to use these sample numbers, since they will provide a valid result for the novice user.

Step #2: Adding a Leadscrew

In the 'Mechanism Selection' area select the leadscrew by clicking on it.

Click on the 'Append' command button.

Note that the 'Visual Axis Setup' is being updated, i.e. the leadscrew is being attached to the gearbox.

Enter the data in the mechanism data entry table as shown in our example.

Naturally, you may enter/modify the data to your liking, but for a first run we recommend to use these sample numbers, since they will provide a valid result for the novice user.

Step 3: Define a load (optional)

In our example, load is the weight that the leadscrew's table has to carry.

The program provides several load options as shown in the picture to the left. In our example we chose the option 'Weight Only'.

In the Load Data Entry Table enter the weight as shown to the left.

This concludes the axis setup. The next step in the motor sizing process is to set up a motion profile (duty cycle).
