Loher – other models: the collective page of three-phase motors outside the named ranges from the Australian GEMS/MEPS register, 0.75 to 160 kW, 2- to 8-pole, German manufacture, efficiencies up to 95.0%
This page gathers the Loher three-phase motors the register could not assign to a named range, from the Australian GEMS/MEPS registration database for electric motors. Loher became an electric motor manufacturer in Ruhstorf an der Rott in Lower Bavaria and has belonged to Siemens since 2005; the Ruhstorf plant still builds industrial motors, today under Siemens's drives division. Almost all models recorded here accordingly come from German manufacture. The type codes mostly begin with the prefix AMGA, followed by the IEC frame size, construction-form letters and pole count, for example AMGA-100LB-04 for a motor of frame size 100L with four poles; the precise meaning of the letters between frame size and pole count (B, D and suffixes) cannot be reliably resolved from the register alone.

The register lists here 240 versions from 0.75 to 160 kW, 2- to 8-pole, with efficiencies from 76.5 to 95.0% at full load and 76.3 to 95.4% at 75% load, protection classes mostly between IP55 and IP66, and frame sizes from 80 to 355 (IEC). For 49 of the models the classification "2005 High Efficiency Level" (roughly IE2) is recorded; the majority carry no such classification.
As a Siemens brand, Loher stands for classic German industrial motor building with a focus on rugged standard motors for machine and plant construction; the models gathered here represent the broad range outside Loher's large, separately maintained series.
For used Loher motors the usual checkpoints are decisive: measure the winding's insulation resistance, check the bearings for running noise and play, check the shaft turns freely, assess the condition of the fan and fan cowl, and match frame size, pole count, protection class and efficiency class on the rating plate against the intended application. For inverter operation, additionally check whether the winding insulation and bearings are rated for it, since the register provides no data on this.

Frequently asked questions
How much power does the Loher AMGA225ME04 have?
The Loher AMGA225ME04 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.
