The Nord 225SH is a three-phase induction motor built by Nord. The rated output is 37 kW. The motor is four-pole, which at 50 Hz gives a synchronous speed of 1,500 rpm. The rated voltage is 415 V. The housing is frame size 225SH. The protection class is IP55. The efficiency is 93.7 per cent at full load, 94.2 per cent at 75 per cent load and 94 per cent at half load. The mounting arrangement to IEC 60034-7 is B14. The motor is built in China. The figures come from the Australian MEPS register under the GEMS Determination 2019; measured to IEC 60034-2-1 (Edition 2.0). Rated output across the Nord range ranges from 0.75 to 55 kW; the 225SH sits in the upper part of that range with 37 kW. Its immediate neighbours are the GBN IE3 225RP below it with 30 kW and the 225MH above it with 45 kW. 40 Nord models across 2 series are on record.

NORD – other electric motors: the collective page of drives from the geared-motor maker in Bargteheide outside the named ranges, frame sizes 80 to 250, 0.75 to 55 kW, four-pole

This page gathers the NORD electric motors the Australian energy-efficiency register (GEMS/MEPS) could not assign to a named range. Getriebebau NORD, founded in 1965 and headquartered in Bargteheide in northern Germany, is a family-owned maker of geared motors, frequency inverters and drive technology with its own manufacturing at several European and Asian sites. The model designations on this page range from the internal factory codes 200XH, 225MH, 225SH and 250WH to the range explicitly marked as IE2, GBN-IE2, and the geared-motor drives designated APAB SK.

The register lists here 9 versions with 0.75 to 55 kW, exclusively four-pole, at voltages of 415 V (4 motors), 230/400 V (3 motors) and 400/690 V (2 motors). Full-load efficiencies range from 82.43 to 94.01%, and at 75% load from 83.03 to 94.5%. Frame sizes run from 80 to 250. As manufacturing countries the register mostly records China, in a few cases also combinations with Germany, Italy and Australia, reflecting NORD's several production sites. Testing mostly followed the 2019 GEMS determination (6 motors) and 2012 (3 motors); two of the nine motors reach the 2018 High Efficiency Level, seven remain unclassified.

NORD positions itself as one of the few drive makers offering gearbox, motor and frequency inverter from a single source, serving conveying plant, agitators and material-flow technology in industry and logistics worldwide.

When buying used, bearing condition and a checked insulation resistance of the winding, the condition of the terminal box and fan cover, a legible nameplate with frame size, voltage marking and, on the GBN-IE2 range, the stated efficiency class matter; on combined geared motors, the gearbox oil level and condition should also be checked. Spares and service run through the NORD sales network.

Frequently asked questions

How much power does the Nord 225SH have?

The Nord 225SH delivers 37 kW.

What to check before buying

  • Match the data plate against the order: frame size, mounting and rating have to agree.
  • Check the ingress rating against the installation site — outdoors or in dust the demands differ.
  • Hold the mounting form and dimensions against the existing seat before ordering.
  • The pole count sets the speed — when replacing an older unit, compare this first.
  • For used units, ask about winding condition and bearing play.
  • Ask about parts availability for this series — the running costs hang on it.
