Drive System Sizing Software Motorizer

What is Drive System Sizing Software Motorizer?

Drive System Sizing Software Motorizer is software that enables you to select the most suitable servo motors for your machine just by setting the machine configuration/specifications and the operation patterns. This software offers a wide range of selectable drive options including sensorless servo and inverters in addition to AC servo.
The software is available for free download. Contact your local sales office for more details.

Sizing Results

When Steps 1 to 3 are complete, the selection result displays multiple possible options.
The result list shows multiple items at once such as motor and drive models, drive capacities, and calculation results of effective load ratio and moment of inertia.

Sizing Results

Click Display condition tab, and control the items displayed in the list by switching ON and OFF.

Condition tab

Tick a box, and click Result details tab to see the calculation results and restrictions, etc.
