Hoyer HMA3 – the range of three-phase motors with multiple protection ratings up to IP66, frame sizes 80 to 132, 0.75 to 7.5 kW, 2- to 6-pole, fully classified High Efficiency Level 2018
Hoyer Motors is a Danish maker of three-phase motors that has its ranges built in China. The HMA3 range covers the small and medium IEC frame sizes; type designations follow the scheme of frame size, build length and pole count, such as HMA3 100L-2 for frame size 100, length L, two-pole. A defining feature of the range is its broad protection-rating approval: each of the 22 motors is certified simultaneously for IP23, IP44, IP55, IP56, IP57, IP65 and IP66, covering several operating environments with one build.

The register lists here 22 versions with 0.75 to 7.5 kW, two- to six-pole, full-load efficiencies from 79.03 to 90.5% and at 75% load from 78.43 to 91.22%. Frame sizes run from 80 to 132, supply voltage is uniformly 400 V. Manufacturing is in China, testing used test method 2-1-1B under the 2019 GEMS determination; all 22 motors reach the 2018 High Efficiency Level.
With its multiple protection-rating certification and uniform 2018 efficiency class, Hoyer positions the HMA3 range in the European and Australia-Pacific market as a standard industrial motor whose mounting position and environment can change by application, from the factory floor to outdoor use, without switching ranges.
When buying used, bearing condition and a checked insulation resistance of the winding, the condition of shaft, key and fan cover, and a legible nameplate with frame size, pole count and mounting code matter; given the wide choice of mounting codes up to the vertical forms V18 and V19, the actual installation should be matched against the approved form. Spares run through Hoyer's distribution.

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.
