FAQs
This motor supports top-terminator box wiring and dual-side rotation, simplifying installation in tight spaces. With a 225 frame, cast-iron construction, and IMB3 IM1001 mounting, ensure flange alignment and proper bearing preload. The Exdb protection and IP66 enclosure demand compliant wiring practices and gasket integrity for hazardous area certification.
IE2 efficiency (Full Load around 93.6%) reduces electrical losses during continuous operation, leading to meaningful energy savings in conveyors, mills, and fans. Over a typical mining shift, this translates to lower kWh consumption and a stronger return on investment, especially in high-duty-cycle installations.
Yes. The motor is specified for direction of rotation on both sides, enabling flexible coupling to existing drives. Its four-pole design supports stable performance under steady-state loads, while the Exd flameproof protection ensures safe operation when loads vary in hazardous environments.
Key certifications include Exdb flameproof protection and IP66 ingress protection, IC411 insulation, and IE2 efficiency. These features align with hazardous-area safety standards and thermal performance requirements, reducing compliance risk and improving fleet-wide safety and reliability.
The rugged cast-iron frame, precision bearings, and robust mounting reduce vibration and wear, extending service life and reducing maintenance frequency. Combined with high IE2 efficiency, the motor delivers lower energy costs and longer uptime, resulting in a favorable total cost of ownership (TCO) for mining fleets and processing plants.
