Which values should you look at on a motor comparison page?

On the comparison screen, first confirm that power and speed are equal, then move on to the values that define the connection: IEC frame, shaft height H, shaft D×E and overall length L. Finally, assess voltage and frame material against the place of use; two models with the same kW can differ markedly on these rows.

Reading order

1. kW and rpm: The row that covers the workload; if there is a difference here, there is no need to look further.
2. Frame and H: Shows whether the motor will sit on the existing baseframe.
3. Shaft D×E: Determines whether the pulley or coupling hub must be re-machined.
4. L: Shows whether it will fit the space on the machine and under the guard.
5. Voltage and material: The panel layout and what the environment demands in terms of vibration, impact and corrosion.

Sample comparison of three models with the same power

The first two models match in connection dimensions; choosing between them is a question of environment and frame robustness. The compact model is shorter and lower; it is an advantage in a tight machine housing, but it does not fit a 160M base or a 42 mm hub. This difference cannot be seen by looking at the power row.

What do empty fields mean?

The DRG motor comparison page shows up to three models side by side and takes its values from the store records. A value without a record is not filled in by guesswork; if you see a “contact us for information” note, confirm that row in writing before ordering. This confirmation matters especially when values such as weight, package dimensions or flange details are needed for transport and installation planning.

You can add the models you want to compare to the list from the product cards in the three-phase motor store or from the page of the 11 kW compact model.
