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: 230/400 V or 400/690 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.

How to Use the Catalog Data When Selecting a Motor

Each table in the catalog answers a different step of the selection. Working through them in order lets you settle both electrical and mechanical fit before you order.

  • Efficiency tables: In the row for your power and speed, read the rated current, efficiency, cosφ and Ist/In. Rated current drives cable, breaker and overload relay sizing; the starting current ratio guides the choice between direct-on-line, star-delta or soft-starter starting.

  • Torque ratios: Starting and maximum torque ratios show whether the motor is strong enough for machines that start under load, such as conveyors or crushers.

  • Dimension drawings: Use shaft diameter and length, frame centre height, foot hole spacing and flange dimensions to check that the motor fits the existing base, coupling or gearbox.

  • Mounting codes: The B3, B5 and B35 codes define the dimensions of the same motor in each mounting arrangement, so choose your mounting first and then read the matching table.

Once you have the type code, download the dimensioned drawing and 3D model from the Technical Drawings section. For more on the product families, see our asynchronous electric motors, cast iron frame motors and IE5 electric motors pages.

Frequently Asked Questions

Is the catalog free of charge?

Yes. You can download the 2026 technical and product catalog from this page as a PDF free of charge.

In which languages is the catalog PDF available?

The catalog is available in Turkish, English and Spanish. Use the version that suits your project or your team.

Where can I download the 2D and 3D drawings?

Dimensioned 2D drawings and 3D STEP models are in the Technical Drawings section. You can also go straight to the 2D technical drawings or 3D technical drawings page.

Which standard are the efficiency values based on?

Efficiency classes are given as IE3, IE4 and IE5 according to IEC 60034-30-1. The values apply to a 50 Hz supply.

What should I do if the model I need is not in the catalog?

Send us the power, speed, mounting type and any special requirements via WhatsApp or +90 532 345 49 86, and we will share a suitable motor and its technical data.
