Birkenbeul Other models

The register lists here 3 versions with 1.1 to 4 kW, all four-pole, with full-load efficiencies from 84.5 to 87.1% and at 75% load from 85.1 to 87.3%. Protection ranges from IP55 to IP66, frame sizes from 90 to 112. Germany and China are recorded as manufacturing countries; testing followed the 2019 GEMS determination with test methods 2-1-1B and A; two of the three motors reach the 2018 High Efficiency Level (roughly IE3), one remains unclassified.

Motors in this power class between 1.1 and 4 kW and frame size 90 to 112 are common drive technology for pumps, fans and smaller conveying plant; registration under the Australian GEMS standard shows that Birkenbeul certifies its range for the Australian market too.

When buying used or replacing, what matters is bearing condition and a checked insulation resistance of the winding, visible overheating marks on the terminal box and fan cover, and a legible nameplate with frame size, pole count and efficiency class; anyone wanting to run the motor on a variable-speed drive should check its inverter suitability beforehand. Spares and support run through Birkenbeul's sales channel.
