Exdb flameproof protection and IP66 enclosure translate to safe, compliant operation in explosive atmospheres, reducing regulatory risk and maintenance interruptions. IE3 efficiency at 75 kW lowers energy costs and thermal stress, delivering noticeable savings over long shift cycles in mining and processing plants. The D connection configuration and 1000 V input simplify integration with existing high-voltage electrical systems, reducing wiring complexity and start-up time. A rugged cast iron frame (280) with 6316/C3 bearings and IMB5/IM3001 mounting provides long bearing life and resilience against dust, vibration, and harsh environments. Designed for up to 1000 m altitude and 40 °C ambient, the motor maintains performance without derating in typical quarry and underground setups. The 2-pole design supports strong starting torque and straightforward drive compatibility for standard mining drives.

FAQs
Install the motor in zones requiring flameproof protection (Exdb) with IP66 enclosure. Use IMB5/IM3001 mounting and ensure the D-end top terminator box is accessible. Connect via the specified D configuration for a 1000 V, 50 Hz system. Verify ambient conditions do not exceed 40 °C and altitude remains within 1000 m to maintain ratings.
The motor delivers 75 kW at 1000 V and 50 Hz with a 2-pole configuration. It operates under IE3 efficiency, has IP66 protection, IC411 insulation class, and Exdb flameproof protection. Duty is S1, and the rated frame is 280 with a cast iron construction suitable for mining environments.
Yes. It is a flameproof Exdb motor with IP66 enclosure, designed for mining operations. The 2-pole, 75 kW output at 1000 V and 50 Hz provides strong starting torque and reliable performance under S1 continuous duty. IMB5/IM3001 mounting and D-End top terminator box support robust installation in harsh underground and surface mining settings.
It features Exdb flameproof protection, IP66 enclosure, and IC411 insulation. The motor is designed for hazardous environments and compliant with high-safety standards. Additional attributes include 2-pole design, 75 kW rating, 1000 V supply, and 50 Hz operation, making it suitable for demanding mining applications.
The Exdb/flameproof design minimizes risk of ignition in explosive atmospheres, reducing downtime. IE3 efficiency lowers energy costs over the motor’s life, while the rugged cast iron frame and bearing arrangement extend service intervals. Compatibility with IMB5/IM3001 mounting and 1000 V systems simplifies integration, delivering faster installation and lower total cost of ownership in mining and processing facilities.
