Loher Other models

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.
