MotorFinder
Technical Design and Calculation for Drive Systems

Selecting a suitable drive is often a combination of mechanics, dynamics, and practical values. The MotorFinder brings structure to this process: You define the axis system and motion, and then receive a well-founded selection of suitable motors—including load capacity and visual plausibility checks.

Find the right drive in just 4 steps

MotorFinder guides you step by step from shaft selection to the right motor recommendation—ideal for project planning, development, and service.

1) Select shaft system

Select the axis system that suits your application—e.g., toothed belt, lead screw, or rotary axis (horizontal/vertical).

2) Select axis type

Specify the axis type and enter the most important axis parameters—either using your own values or predefined parameters.

3) Time-distance profiles

Define motion phases with distance, times, ramps (ACC/DEC), moving mass, and external force. The corresponding time-distance diagram is visualized directly.

4) Suitable motors

Receive a selection of suitable motors—including load capacity based on your calculation. Optionally, the appropriate gearbox is also displayed.

Key features for everyday use

• Save & continue later: Calculations can be saved and viewed or edited at any time in your personal area.
• PDF export: Conveniently export results and configurations as PDFs—ideal for documentation and coordination.
• Targeted filtering: Filters for motor type, motor size (stepper motors/servo motors), control, brake, and encoder.
• Load at a glance: The load is calculated and displayed directly from the calculation.
• Visual plausibility checks: Time-distance diagram for motion and display of the phases in the motor characteristic curve.
• Optional with gearbox: Depending on the selection, the appropriate gearbox is automatically included/displayed.

Visual verification: Diagrams instead of guesswork

Two visualizations provide quick confirmation: The time-distance diagram shows the motion sequence, and the motor characteristic curve marks the relevant phases directly in the diagram.

Phases directly in the motor characteristic curve

The calculated phases are displayed as points/markers on the characteristic curve—so you can immediately see whether speed and torque requirements are within the appropriate range.

The entire cycle is clearly displayed—including stops and direction changes.
