FAQs
For safe, compliant installation in hazardous zones, mount the motor using IMB5 IM3001 compatibility, position the top-terminated box for easy wiring access, and verify Exdb protection, IP66 seal, and flameproof ratings. Ensure a stable foundation on cast-iron feet and allow for proper cooling clearances in confined underground spaces.
The motor delivers IE2 efficiency, Exdb flameproof protection, and IP66 ingress protection. It is a 4-pole design with voltage code D and a duty class of S1, intended for continuous service at ambient up to 40 °C and altitude up to 1000 m, ensuring reliable operation in harsh environments.
This motor is designed for constant-load, steady-state operation (S1 duty) with a fixed-speed profile. It is not a dual-speed unit, so for variable-speed requirements consider compatible drive systems with VFDs and verify load profiles to maintain efficiency and protection.
Key certifications include Exdb flameproof protection and IP66 enclosure rating, with IEC-based design data such as IC411 insulation and IMB5 IM3001 mounting. These features support compliance in mining and other hazardous environments and align with global industry safety standards.
Expect reduced maintenance downtime due to rugged cast-iron construction and high IP rating, plus energy savings from IE2 efficiency. A proactive plan should include bearing inspection (6315/C3), lubrication schedules for 6313/C3 NDE bearings, and periodic inspections of the Exdb enclosure and seals to sustain long-term uptime.
