Brook Crompton Other models

The register lists here 161 versions from 0.75 to 160 kW, 2- to 8-pole, with efficiencies from 72.4 to 96.2% at full load and 72.4 to 96.3% at 75% load, protection classes mostly between IP54 and IP66, and frame sizes from 80 to 355 (IEC). No GEMS "High Efficiency Level" classification is recorded for any of the 161 models.

As a Wolong brand, Brook Crompton represents the continuation of British electric motor tradition under Chinese group ownership, with manufacturing today concentrated mainly in Poland and China; the models gathered here represent the broad range outside the separately maintained series.

For used Brook Crompton 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, protection class and efficiency class on the rating plate against the intended application. For inverter operation, check separately whether the winding insulation and bearings are rated for it, since the register provides no data on this.
