Hoyer Other models

The register lists here 3 versions with 1.1 to 1.5 kW, two- to six-pole, with full-load efficiencies from 78.63 to 81.64% and at 75% load from 79.32 to 81.97%. Protection is uniformly IP56, frame size runs from 80 to 100, mounting codes are B5 and B14. China is recorded as the manufacturing country; testing followed the 2019 GEMS determination with test method A; none of the three motors reaches a High Efficiency classification under GEMS.

Motors in this small power class of around 1 to 1.5 kW with the rugged IP56 protection are built for use in harsh surroundings, for instance in agriculture or outdoor installations; registration under the Australian GEMS standard shows that Hoyer certifies its range for the Australian market too, while manufacture of the registered range is based in China.

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 and pole count; anyone wanting to run the motor on a variable-speed drive should check its inverter suitability beforehand. Spares run through Hoyer's sales channel.
