Motor Model Numbering System

September 10, 2013

Every fractional horsepower motor manufacturer has their own model numbering system. It may seem like we all chose random letter and number combinations, however, there is a “method to our madness.”

Here is a quick explanation of Groschopp’s model numbering system to help you understand what our sales and engineering teams are talking about the next time you contact us.

For our gear motors, we combine the motor and gearbox model numbers.

There you have it, a crash course on our model numbering system. Now you are set to browse our product pages armed with more information that will hopefully help you find the right motor for your application. Don’t forget, that we have thousands more combinations available than what you see on our site. If you can’t find what you need online, give us a call. One of our regional account managers will be happy to help you find the best motor for you application.

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.
