NORD

NORD Drivesystems, founded in 1965 in Bargteheide, Germany, is a manufacturer of geared motors, speed reducers, and drive electronics. The product line available through 3G Electric focuses on hollow shaft direct-drive right angle speed reducers and washdown-duty AC gearmotors. These units are designed for industrial applications requiring precise speed reduction and torque multiplication in confined spaces. The speed reducers in the SK1SI series offer ratios from 15:1 to 100:1, with output speeds ranging from 18 RPM to 117 RPM and maximum input power from 0.75 hp to 1.75 hp. Output torque capacities span 434 in-lb to 1655 in-lb, depending on the model. Frame sizes include 56C and 140TC, with hollow shaft configurations that allow direct mounting on driven shafts without additional couplings. The right angle gear geometry provides a compact footprint suitable for material handling, conveyor systems, and process equipment. The washdown-duty AC gearmotor (SKU 5YW33) features a TEFC enclosure, 3-phase power, and a right angle output shaft, rated at 137 RPM with 222 in-lb maximum torque. NORD components are built to IP55 or higher ingress protection standards, with cast iron housings and helical-bevel gear sets for efficiency and durability. 3G Electric stocks 141 SKUs of NORD gearmotors and speed reducers, each with downloadable datasheets and logistics support for global shipment. The selection covers common reduction ratios and input configurations, enabling engineers to match drive requirements without custom fabrication. All units are supplied with manufacturer part numbers for traceability and cross-referencing.

Frequently asked questions

Common questions about NORD from 3G Electric.

What are the available reduction ratios for NORD hollow shaft speed reducers from 3G Electric?

The NORD SK1SI series hollow shaft speed reducers stocked by 3G Electric are available in ratios of 15:1, 20:1, 30:1, 60:1, 80:1, and 100:1. These ratios correspond to output speeds from 117 RPM down to 18 RPM at 60 Hz input. The specific ratio determines the output torque capacity, which ranges from 434 in-lb to 1655 in-lb. Selection should be based on the driven load's speed and torque requirements.

What frame sizes are available for NORD speed reducers?

NORD speed reducers in the 3G Electric catalog are offered with 56C or 140TC input flanges. The 56C frame is common for smaller motors up to 1.75 hp, while the 140TC frame accommodates higher input power up to 1.13 hp in the listed models. The hollow shaft design allows direct mounting on the driven shaft, eliminating the need for a coupling. Verify the motor frame size and shaft diameter before ordering.

Are NORD washdown-duty gearmotors suitable for food processing environments?

The NORD washdown-duty AC gearmotor (SKU 5YW33) features a TEFC enclosure and right angle output shaft, designed to resist moisture and particulate ingress. While it is rated for washdown applications, specific suitability for food processing depends on the cleaning chemicals and pressure levels used. The unit's IP rating and stainless steel options should be confirmed against the facility's sanitation requirements. 3G Electric can provide datasheets with detailed environmental ratings.

Can NORD speed reducers be mounted in any orientation?

Yes, the NORD SK1SI series speed reducers are labeled 'Any Angle' in the product specifications, indicating they can be mounted in horizontal, vertical, or inclined positions. The hollow shaft design and oil lubrication system accommodate various orientations without performance degradation. However, ensure the breather and drain plugs are positioned correctly for the chosen mounting angle to prevent oil leakage or inadequate lubrication.

What is the maximum input horsepower for NORD speed reducers in the 3G Electric inventory?

The maximum input horsepower varies by model. For the 56C frame units, input power ranges from 0.75 hp to 1.75 hp. The 140TC frame units accept up to 1.13 hp. These limits are based on the gearbox's thermal and mechanical capacity at the specified ratio. Exceeding these values may cause overheating or gear failure. Always match the motor's rated power to the reducer's input limit.

Does 3G Electric supply NORD products?
