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.

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.
