Lafert AMHEBY – high-efficiency motors from San Donà di Piave: MEPS-registered range, frame sizes 80 to 160, 0.75 to 15 kW, 4-pole, IP54/IP55 protection, efficiency up to 91.28%
Lafert is an Italian electric motor manufacturer headquartered in San Donà di Piave near Venice. AMHE denotes the company's high-efficiency range; the types carried in the register, such as AMHEBY 112M AA4 or AMHEBY 160L ZA4, carry the frame size as a three-digit number and the pole count as the final digit before the letter suffix, matching the frame-size and pole-count values in the register.

The register lists here 6 versions with 0.75 to 15 kW rated output, all 4-pole, at voltages of 230/400 V and 400/690 V. Full-load efficiency ranges from 80.27 to 91.28%, and at 75% load from 80.42 to 91.46%. Frame sizes run from 80 to 160, protection is mostly IP55, with one motor at IP54. Testing followed the GEMS determinations of 2012 and 2019 using test methods A and 2-1-1B.
As a high-efficiency programme, the AMHE range targets applications where motor efficiency over the operating life matters more than purchase price, such as continuously running pumps and fans, competing with the premium motors of ABB, Siemens and WEG. The range is manufactured in Italy.
When buying used, 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 note the voltage variant (230/400 V or 400/690 V). Spares and support run through the Lafert sales network.

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.
