Flameproof Exdb protection combined with IP66 enclosure delivers safe operation in explosive atmospheres and washdown-heavy environments, reducing risk and unplanned downtime while supporting reliable performance in mining drives and other safety-critical applications. The business impact is clear: heightened compliance posture and lower total cost of ownership due to fewer emergency repairs and longer service intervals. In practice, this motor enables installers to reduce protection planning without sacrificing throughput, enabling smoother conveyor and hoist operation in mineral processing facilities. IE3 efficiency translates into meaningful energy savings over the motor’s lifetime, particularly on load profiles common in mining and material handling. The 55 kW rating at 400 V and 50 Hz ensures robust torque delivery for start-up and steady operation, improving plant uptime and productivity. Compatibility with Y connections and IMB5/IM3001 mounting simplifies integration with existing electrical architectures and mounting schemes across sites.

FAQs
This motor uses a Y (star) connection and is designed for 400 V, 50 Hz operation. With IMB5/IM3001 mounting and a top-entry termination box, it integrates easily into standard plant electrical rooms. Ensure the drive and starter arrangements are rated for Exdb environments, verify the 3GJM designation matches your control cabinet, and confirm the operating altitude (up to 1000 m) and ambient temperature (up to 40 °C) are within site specifications.
The motor features Exdb flameproof protection and an IP66 enclosure, making it suitable for explosive atmospheres and washdown conditions. Insulation is rated ICFL, and the unit supports IMB5/IM3001 mounting. These protections help meet mining and industrial safety standards while delivering robust performance in challenging sites.
IE3 efficiency indicates high energy performance, with Full Load efficiency around 94.6% at 50 Hz (and higher at 60 Hz). In mining applications with conveyors and fans running long hours, this can reduce electrical energy consumption, lower operating costs, and improve MTBF by delivering consistent torque with reduced losses during peak load periods.
Common applications include mining drives, conveyor systems, and bulk material handling where dependable torque, safe operation, and longevity are essential. The 55 kW rating, 4-pole design, and Exdb flameproof protection make it suitable for hazardous environments, while IMB5/IM3001 mounting supports versatile installation in both vertical and horizontal configurations.
The combination of flameproof protection, IP66 enclosure, and IE3 efficiency yields reduced downtime and lower energy costs over the motor’s life. Cast iron frames, bearing arrangements (6315/C3 and 6313/C3), and robust IMB5/IM3001 mounting contribute to longer MTBF and easier maintenance planning, translating into lower lifecycle costs for safety-critical mining drives.
