Flameproof Exdb protection paired with an IP66 enclosure reduces ignition risk and protects windings, terminals, and bearings from dust, moisture, and spray. In mining installations—whether underground haulage, ore conveyors, or slurry pumps—the combination supports long service intervals and safer startup sequences. IE3 efficiency is in the mid-94% range across 50 Hz operation—Full Load 94.6% and 75%/50% partial loads around 94.5–93.7%. At 60 Hz, Full Load is about 95.4% with 75% and 50% around 95.2% and 94.1%. Operators benefit from lower energy consumption, cooler operation, and reduced cooling requirements in hot environments. The 55 kW output, 4-pole design, and 400 V supply provide strong starting torque and stable speed control for heavy-load mining conveyors and pumps. Frame Size 250, IMB3/IM1001 mounting, and a top terminator box streamline installation, retrofit, and service access, reducing downtime and enabling quicker maintenance. Altitude tolerance up to 1000 m and ambient up to 40 °C, combined with Ex protection and IC411 insulation, ensure equipment reliability in open pits and underground chambers. Bearing arrangements 6315/C3 and 6313/C3 extend service life, supporting predictable performance and easier maintenance planning.

FAQs
Key installation considerations include Exdb flameproof protection and an IP66 enclosure to guard against dust, moisture, and explosive atmospheres. Ensure the terminator box is located at the top and use IMB3/IM1001 mounting to match standard mining frames. Verify assembly clearances and seal integrity during retrofits to maintain compliance and performance in challenging sites.
This motor combines Exdb flameproof protection with an IP66 enclosure and IE3 efficiency, delivering safe operation in explosive atmospheres while reducing energy costs. The 55 kW rating, 4-pole design, 400 V supply, and 50 Hz compatibility suit heavy-load mining equipment such as conveyors and pumps, enabling reliable performance both underground and on the surface.
Yes. It features Exdb flameproof protection and IP66 enclosure for hazardous environments, IC411 insulation, and IMB3/IM1001 mounting compatibility, aligning with typical mining safety and explosion-protection standards. The 55 kW output at 400 V and 50 Hz supports continuous duty in demanding applications while maintaining safety and regulatory compliance.
The motor is IE3-class efficient, with Full Load efficiency around 94.6% at 50 Hz and approximately 94.5% at 75% load and 93.7% at 50% load. At 60 Hz, Full Load efficiency is about 95.4%, with partial-load values near 95.2% and 94.1%. This supports energy savings across steady-state mining operations and variable-load scenarios.
Expect a robust lifecycle with 6315/C3 and 6313/C3 bearings, IMB3/IM1001 mounting, and top-placed terminator box for easy service access. The Ex-protected design reduces contamination risks, and the 1000 m altitude and 40 °C ambient ratings help maintain performance in open pits and underground environments, lowering downtime and maintenance costs over the motor’s life.
