An IE3 electric motor catalog gathers, in a single reference, all the technical data a plant needs when selecting the right motor. Power, speed, mounting type, frame dimensions and efficiency values form the core of the catalog, allowing the correct motor for a project to be specified at the desk without trial and error.

What Information the Catalog Contains

For each motor an IE3 catalog lists rated power (0.55–355 kW), pole-dependent speed at 50 Hz, rated current, power factor, weight and frame size. Standard equipment such as IP55 protection, Class F insulation and S1 continuous duty is also stated, indicating the environment in which the motor can operate.

Connection and Mounting Options

The catalog presents B3 foot-mounted, B5 flange and B14 face versions separately for the same power. A flange type suits a motor coupled directly to a pump, while a foot-mounted type fits conveyor and gearbox applications. Choosing the right mounting code from the catalog eliminates field mismatch and the need for adapters.

Reading the Efficiency Class From the Catalog

IEC 60034-30-1 classifies motors from IE1 to IE5. The IE3 (Premium) class is shown in the catalog with the guaranteed minimum efficiency percentage for each power step. This value can be used directly to estimate annual energy consumption and to compare different models.

The DRG Motor IE3 Product Range

With its İzmir-based manufacturing, DRG Motor offers cast iron and aluminium IE3 motors across a wide power and speed range. To help you pick the model that matches the requirement in your catalog, it shares technical drawings, dimension tables and current stock data on request.
