Feature → Business Impact → Application: The 85 kW output at 400 V / 50 Hz delivers strong starting torque and consistent load handling, improving process stability and reducing drive-fill time in heavy industry applications such as pumps and fans. This translates to lower energy waste and faster response in critical lines. The IP55 enclosure coupled with IC410 insulation protects internal windings from dust and moisture, extending service life in harsh environments and lowering maintenance frequency for plants with variable humidity or particulate matter. IMB3/IM1001 mounting and a cast iron frame (Size 400) provide rigidity and vibration damping, enabling long bearing life and smoother operation on conveyors and mixers. The 8-pole, single-speed design simplifies retrofits and supports standard 400 V, 50 Hz power systems, reducing integration risk in mixed fleets. Altitude capacity up to 1000 m and a 40 °C ambient ceiling ensure reliable performance in diverse geographic locations. The D connection configuration streamlines panel wiring, while the 6324/C3 bearings and S9 duty rating reinforce reliability for continuous-duty industrial drives. Overall, this motor delivers measurable efficiency gains, lower total cost of ownership, and improved uptime for industrial drive systems in demanding settings.

FAQs
For IMB3 mounting, ensure the IMB3/IM1001 framework is compatible with the frame size 400 and that the terminator box is located as specified (N-End top). Use the D connection configuration for straightforward integration with standard 400 V, 50 Hz power supplies. Verify alignment and bearing preload (6324/C3) during installation to minimize start-up wear and maintain efficient operation.
The motor is rated for Input Voltage 400 V and Frequency 50 Hz, delivering 85 kW at 8 poles. With an IP55 enclosure and IC410 insulation, it supports continuous operation under typical plant conditions. Ensure your drive system and soft-start or VFD controls are configured for 400 V, 50 Hz operation and account for shaft alignment and torque requirements during commissioning.
Yes. The Type of Duty is S9, indicating long-period continuous operation with intermittent rest. This makes the motor well-suited for conveyors, mills, and process lines where sustained torque is required yet duty cycles include cool-down periods. Use appropriate cooling and bearing maintenance schedules to sustain performance over the motor’s life in demanding environments.
Key specifications include IP55 protection, IC410 insulation, and IMB3/IM1001 mounting, which support rugged industrial use and reliable performance. The motor uses a cast iron frame (size 400) for durability, with a 1000 m altitude tolerance and 40 °C ambient rating. These attributes align with common industrial standards and mounting conventions in heavy industry.
The combination of 85 kW output, IP55 protection, robust bearings (6324/C3), and IMB3/IM1001 mounting reduces unplanned downtime and extends service intervals. Energy efficiency, reduced cooling load, and dependable operation under S9 duty contribute to a lower total cost of ownership and faster payback in plants with high uptime requirements.
