FAQ
Frequently asked questions
Answers to the most common questions on motor sizing.
Required are mechanical data (torque, speed, inertia, acceleration, gearbox, installation space), electrical data (voltage, current, efficiency, starting behaviour, control range) and the operating conditions (duty type S1/S2/S3, cyclic duration factor, temperature, protection class, cooling).
In four steps: analysing application and load data, calculating operating points and reserves, selecting motor, gearbox and options, and a final technical review.
Yes, our motor sizing calculator gives a first technical estimate based on your inputs – for a reliable sizing we then review the results together.
Yes, the approach applies to AC and servo motors as well as DC motors – the required sizing data are comparable.
Next step
Start with the data you already know
We can identify missing parameters together and distinguish required reserves from unnecessary oversizing.
