8. Case Studies
Medical Bed: Quiet, Synchronized Motion, Dual Output Gearmotor Deliveres
Highly specialized surgical procedures such as spinal, joint replacement and orthopedic trauma surgery require auto-
mated operating room tables that can be positioned with extreme accuracy. Just as important as positional accuracy are
high torque output and quiet operation, in a compact gearmotor solution that can drive up to a 500 pound load. When
one of the world’s leading designers and manufacturers of such innovative medical products was faced with such a
challenge, they partnered with Groschopp to tackle this tough job.
The Challenge
• Gearmotor needed to drive two positionally synchronized arms on a surgical table
• High torque output, intermittent duty for loads up to 500 pounds
• Quiet operation for medical/OR environment
• 20 VDC power supply limitation
The Solution
• Permanent magnet DC motor customized for high torque and low noise
• Two planetary speed reducers driven by one common motor shaft
• Special speed reducer component configuration and alignment to minimize noise

Grain Hopper
This OEM is a premier supplier to the agricultural equipment industry. They had a new product design for an automated hopper motor
assembly to retrofit grain trailers and wagons.
The Challenge
• Ingress protection (IP) against dust and particulates (meet or exceed IP66 ratings)
• HIgh vibration, harsh environment package
• HIgh torque output for intermittent loads
• 12 VDC, 100A power supply limitation
The Solution
• Permanent magnet DC motor operating at 12V, 100 Amp current limit
• HIgh efficiency planetary speed reducer with strengthened output gears
• Special corrosion protection features and rugged duty package enhancements

9. Case Studies
Plastic Injection Feeder
A manufacturer or high quality volumetric additive plastic injection feeds and blending systems for plastic augers came to Groshcopp
looking for a variety of motors for multiple applications. Unsure of their exact specifications, Groschopp engineers helped the manufac-
turer narrow their focus to a few specific motors and identitfy their specifications to pinpoint which gearmotors would best meet their
needs. The gearmotors needed to function reliably in a heated rotomold process, while meeting the customer’s demand to drive a preci-
sion feed auger into varying size molds.
The Challenge
• AC/DC voltages
• Short lead time
• Varying reducer sizes for multiple applications
The Solution
• 90 VDC or 115 VAC motor with a parallel shaft gearbox
• Three different size options
• 48 hour prototype turn-around time for proof of concept

Milk Shake Blending Machine
A maker of commercfial food preparation equipment needed a motor to be used to power a milk shake blending machine
The Challenge
• The motor must be able to stand up to the difficult environment of a fast food restaurant
• Continuous duty for long periods of time
• In blending ice cream, the motor must be sealed against splashing liquids
• Must be able to withstand frequent cleaning
• Needed to fit in custom housing
The Solution
• Permanent magnet DC motor with cusom endbells
• Extended stainless steel shaft and sealed bearings
• Special windings and custom power cord were used to meet the customer’s specifications
