With 15 kW output and an 8-pole design, this motor delivers strong torque at 400 V and 50 Hz, optimized for smooth drive performance. The 3-phase, Y-connected configuration reduces line current at full load, improving wiring efficiency and reducing installation costs. In addition, the IP55 enclosure guards against dust and water ingress in harsh environments, while IC410 insulation supports long service life in demanding applications. The cast-iron frame (280) and bearing configuration (6316/C3) provide rugged mechanical robustness, minimizing vibration and extending bearing life. IMB3/IM1001 mounting compatibility simplifies retrofits and new installations alike, enabling faster commissioning across conveyors, fans and pumps. All of these factors contribute to measurable energy savings, reduced maintenance, and greater system reliability.
