Ingersoll Rand 90S
Series: Other models
Ingersoll Rand – other models: the collective page of three-phase motors from the Australian GEMS/MEPS register, 0.75 to 160 kW, 2- to 6-pole, Chinese manufacture, efficiencies up to 96.1%
This page gathers the three-phase motors registered under the Ingersoll Rand brand in the Australian GEMS/MEPS register that could not be assigned to a named range. Ingersoll Rand is best known for compressed-air and compressor technology; the motors recorded here include typical drive motors for compressor packages and related units in this size class. All 181 models come from Chinese manufacture. Some of the type codes are plain order or part numbers (for instance 18993055), others are short frame-size codes such as 112M, 132S or 315L following the IEC scheme; no consistent type logic spanning both naming styles can be derived from them.

The register lists here 181 versions from 0.75 to 160 kW, 2- to 6-pole, with efficiencies from 72.12 to 96.1% at full load and 70.12 to 96.36% at 75% load, mostly protection class IP55 (alongside IP54 and IP56), and frame sizes from 90 to 315 (IEC). Of the 162 models with a GEMS classification recorded, 9 reach the "2005 High Efficiency Level"; the rest carry no such classification.
In the register, Ingersoll Rand thus mainly reflects the drive-motor requirements of its own compressor production; the range of frame sizes and outputs visibly follows the requirements of different compressor ranges rather than a standalone electric-motor catalogue.
For used Ingersoll Rand drive motors, the usual checkpoints apply: 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 and efficiency class on the rating plate against the original compressor unit, if the motor came from such an assembly. For inverter operation, check separately whether the winding insulation and bearings are rated for it.

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.
