What Groschopp does
Groschopp, Inc. is a privately held American industrial automation company founded in 1930 (originally as Wincharger) and headquartered at 420 15th St NE, Sioux Center, Iowa, where it also operates its primary manufacturing facility. The company specializes in fractional horsepower electric motors and gearmotors (under 1hp/746W), offering DC, AC, Brushless DC (BLDC), and Universal motor technologies paired with four gearbox configurations: Parallel Shaft, Planetary, Right Angle, and Right Angle Planetary. Products are sold as standard units, modified configurations, or fully custom designs, supporting voltages from 12-180 VDC and 115-230 VAC. The company runs an in-house engineering department spanning OEM prototyping to MOTORTEC performance assessment and maintains a proprietary product configuration database covering 100,000+ possible motor and gearbox combinations.
The revenue model is built on direct hardware sales to OEM manufacturers and the industrial replacement market. Pricing is quote-based, reflecting motor type, voltage, speed, torque, power requirements, gearbox configuration, customization, and order volume, with a dedicated high-volume quote process for enterprise customers. Groschopp runs a sales-led go-to-market motion combining a toll-free phone line, email, online quote request forms, and a public-facing Motor Search Tool and MOTORTEC Speed-Torque-Power (STP) Calculator that move customers from specification into the sales funnel. There is no disclosed distributor or channel partner network.
Groschopp serves a horizontally diversified customer base spanning industries that include solar energy, golf equipment, automotive accessibility, car wash systems, plastic processing, packaging machinery, medical imaging (X-ray and MRI cooling pumps), water treatment, vapor recovery, and construction fluid power. Documented engineering outcomes include IP66-rated motors for wet environments, 50,000+ hour continuous-duty life testing for MRI cooling applications, 48-hour prototype turnaround for proof-of-concept work, and a proprietary Flux Ring Commutation Technology for custom BLDC motors. The company employs approximately 200 people at its Iowa facility and is privately held with no disclosed institutional investors, parent company, or external funding rounds.

Groschopp competitors and assessment
Company assessmentBroad incumbents
- Nidec Corporation: World's largest motor manufacturer spanning small, fractional, and industrial motors. Competes indirectly via global OEMs and could expand down into fractional HP with greater cost leverage than Groschopp.
- SEW-Eurodrive: Global leader in gearmotors, drive electronics, and motion control for industrial automation. Overlaps Groschopp in gearmotor category but at much larger scale, broader power range, and with full mechatronic system offerings.
- Dayton Electric / WEG: Global motor and drive manufacturer with fractional HP offerings historically sold under Dayton brand in the US. Broad incumbent in the same motor categories with significantly larger scale, distribution, and R&D resources.
Emerging players
- Dart Controls: US-based manufacturer specializing in DC motor speed controls and small fractional HP drives. Comparable as a niche motion component supplier targeting OEM customers, complementary to Groschopp's motor control offerings.
- Cramer Motors (formerly Crouzet Motors / SECM): European fractional horsepower motor and gearmotor specialist focused on compact DC, BLDC, and synchronous motors. Comparable fractional HP product scope with stronger European footprint versus Groschopp's US focus.
Direct peers
- Oriental Motor USA: Global fractional horsepower motor manufacturer offering AC, DC, BLDC, stepper, and gearmotors with extensive online configuration tools. Competes head-to-head in the same fractional HP OEM niche with broader catalog and global footprint.
- Allied Motion Technologies: Specialty fractional and integral horsepower motor/drive manufacturer serving industrial, vehicle, medical, and aerospace OEMs. Comparable on custom fractional HP motor solutions for OEM applications, though broader in scope and publicly traded.
- Bodine Electric Company: US-based fractional horsepower gearmotor and motor manufacturer with standard, modified, and custom AC, DC, and BLDC offerings. Directly comparable in product scope (sub-1HP motors + gearboxes), custom engineering approach, and OEM customer focus.
- Bison Gear & Engineering: American fractional horsepower gearmotor and motor manufacturer focused on parallel shaft, right angle, and planetary gearmotors. Closely comparable on fractional HP product mix, gearmotor configurability, and OEM direct-sales model.
- Leeson Electric (Regal Rexnord): Heritage American fractional and integral horsepower motor and gearmotor brand now part of Regal Rexnord. Directly comparable fractional HP product lines and OEM customer base, but operates as part of a much larger industrial portfolio.
