The HEM Motor Electric Motors Technical and Product Catalog 2026 is a 32-page technical reference that brings our complete three-phase asynchronous motor range together in a single document. It is prepared for engineers selecting motors, project managers, maintenance teams and purchasing departments. Download the PDF on this page to access the full catalog free of charge.

What Is Inside the Catalog?

The catalog contains all the data you need to select a motor correctly and integrate it into your project:

  • Complete product ranges for IE3, IE4 and IE5 efficiency classes,
  • Rated power (kW), speed (rpm) and rated current (A) for every power step,
  • Efficiency (η %), power factor (cosφ) and starting current ratio (Ist/In),
  • Starting torque and maximum torque ratios,
  • Frame sizes and dimensions for B3 / B5 / B35 mounting types,
  • Terminal connection diagrams and operating conditions.

Covered Motor Range

  • Efficiency class: IE3 · IE4 · IE5
  • Power range: 0.25 – 355 kW
  • Number of poles: 2 · 4 · 6 · 8 poles
  • Protection class: IP55
  • Duty type: S1 (continuous duty)
  • Rated voltage / frequency: 380 V / 50 Hz

How to Use the Catalog

First determine the power and speed your application requires, then pick the matching type code from the table of the relevant efficiency class. To verify the mounting fit of the motor you selected, use the dimensioned drawings on the 2D technical drawings page, or the 3D technical drawings page if you need a three-dimensional model.

Cannot Find the Model You Need?

For power ratings, speeds or special frames not listed in the catalog, please contact our technical team. We will identify the right motor for your application together and share up-to-date technical data and drawings with you.
