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

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
