Automated Prison Doors

Groschopp worked with a manufacturer to create an automated system for moving heavy prison doors (weighing anywhere from 200-1200 lbs each). For this application, tight installation using a right angle reducer and the smallest possible motor was important. Because the prison doors would only be operating intermittently, Groschopp was able to use a smaller—and less […]

Heavy Duty Impact Wrench

In the heat of battle, the last thing someone should have to worry about is motor reliability. Groschopp helped with the design of a heavy-duty impact wrench to be used in Abrams Tanks, Bradley Fighting Machines, and Humvees during battle. This wrench was built with a custom universal parts set motor design to allow high […]

Professional Woodworking Tool

Groschopp’s capabilities go beyond just designing and manufacturing motors. Part of what sets them apart is their ability to create custom integrated solutions and assemble them in the Groschopp facility. For some customers, this saves time and money. That was the case for a manufacturer of pocket hole jointer tools. Groschopp not only engineered a custom […]

Automated Sliding Doors

Groschopp’s DC planetary gearmotor provided a low speed, high starting torque solution that could smoothly control a three to four element automated sliding glass door. The compact, inline design of the motor allowed it to fit discretely within a wall cavity. The motor was designed with an inexpensive integrated control that could set start and […]

Smoke Curtain

When it comes to safety, having a motor that is reliable is a must. After testing motors from several different manufacturers, an automated smoke curtain OEM trusted Groschopp to do the job. A top concern for this OEM was the reliability of the motor after prolonged periods of inactivity. Because the motor would rarely be […]

Distribution Center Conveyor

Distribution centers are a demanding environment for electric motors. Often times, the conveyor belts are running 24 hours a day, only stopping for maintenance. In addition, the conveyor belt systems Groschopp worked with varied from nearly no load to carrying parcels weighing several hundred pounds. Groschopp built a standard AC motor with a right angle […]

Twist Tie Machine

This OEM is a leading manufacturer of commercial baking equipment and accessories. They needed a motor to be used in four different applications on a bread packaging machine. As a successful supplier of brushed DC motors for the company’s older machine, Groschopp had the opportunity to supply motors for the OEM’s newest design. The Challenge […]

X-ray Cooling Pump

This customer is a premier independent supplier of X-ray tubes and flat panel detectors, serving the leading manufacturers of imaging equipment for medical diagnostics, as well as industrial inspection and security products. A stator was needed for a diagnostic X-ray machine. The Challenge Everything about this application is extreme – high operating temperatures, immersion in […]

MRI Cooling Pump

Medical equipment must be reliable and have a long life even with hours of continual usage. An MRI cooling pump manufacturer came to Groschopp because they were having extensive failures with the motors from their previous supplier. Groschopp did some testing and found the old motors were failing due to heat issues. The two engineering […]

Laboratory Mixer

A manufacturer of overhead mixers to grind plant seed materials needed a motor that could operate at extremely high speeds and high torque in order to grind the material into dust. Groschopp worked with them on a few prototypes to find something that could hold up to their torque requirements. After heat-treating the shafts to […]

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.
