Compare Motor Types

Choosing the best motor or gearbox selection to fit your application can be an overwhelming experience for those less familiar with fractional horsepower electric motors. This page will provide you with a quick way to compare motor types.

Speed vs. Torque: Compare Motor Types

As you can see, Universal motors can run at extremely high speeds but only at very low torque levels. AC motors hold a fairly consistent speed over a range of torque. DC and Brushless motors have similar curves—low speed and high torque—but Brushless motors dramatically exceed the torque levels of all other motor options at similar frame sizes.

AC Induction, PMDC, DC Brushless and Universal motors all have different speed-torque curves.

How to use the Motor Search Tool

Narrow your search by selecting motor type, gearbox, voltage, and phase options for your desired motor.

Select a dominant variable: choose one of the three parameters to narrow your search. The selected variable determines which slider bar you will be able to manually move.

Use the slider corresponding to your dominant variable to further narrow your motor selection. The other sliders will automatically move to show available ranges based on the range of your selected variable.

Results will upload as your search criteria changes. If you have any questions regarding your results or how to use the search tool, you can chat with us using the green tab on the left-hand side of your screen.


Note: Groschopp Universal motors are custom built to fit your application so no additional options are available to narrow the search. Selecting the Universal motor type will prompt a message taking you to the Universal product page.
