5 Things We Believe In:

     1.  Redefining Quality

Quality Product. Quality People. Quality Process. We know that many of our direct competitors also sell high quality products, but we provide a sense of pride and integrity to match our quality. You deserve a company that stands by their product, even if issues arise. We believe in treating you with respect, and working to address obstacles quickly and with you in mind. You should be able to count on your motor manufacturer holding its departments to a high standard of procedure. That is why we are ISO9001 accredited.

     2.  Pooling Our Knowledge

All our departments operate under the same roof. This allows our engineering and sales departments to brainstorm ideas as a group. We believe having an inside sales team benefits you because we can bounce ideas around with each other and pull from different experience and expertise levels.

     3.  Not wasting your time

Because we are a privately-owned company, there are less hoops to jump through when decisions need to be made. This means we are capable of shorter lead times and faster responses than many of our competitors. We have a fast-track department that is specifically designed to build and ship motors within 48 hours. If you order in small quantities or are looking for sample motors, this option may be available to you.

     4.  Not wasting your money

Our sales and engineering teams designed a sophisticated software to search through hundreds of thousands of motor and gearbox combinations. We take your specific environmental factors and duty cycle into consideration, ensuring you will get the best motor for your application. This is important because selecting the wrong motor can result in a more expensive motor than is needed or one with a shortened life expectancy. Ask us about testing your current gearmotor to determine the actual specifications your application requires.

     5.  Being educators and students

As time progresses, so do technology and industry standards. Don’t you want a partner who does the same? We believe in continually improving our craft and are consistently seeking ways to increase efficiency and performance of our electric motors. We partner with several organizations in the industry to continue learning. Many of our leaders volunteer their time at local high schools and colleges to inspire and encourage the next generation. We also believe in sharing our knowledge with you. Our desire to teach extends to our website; we offer several online resources including how-to videos, blogs and engineering tools for anyone who wants to learn more about motors and engineering.

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.
