FAQs
Install the 280 frame, Cast Iron motor on a rigid base using IMB5 IM3001 mounting. Ensure proper alignment with the driven pulley or gear, coarse alignment tolerances, and secure electrical connections. Use a suitable soft-start or VFD to manage inrush and torque, and verify IP55 seals are intact for dust and moisture protection in conveyor environments.
IP55 protection guards against dust ingress and water jets, while IC411 insulation supports sustained performance in moderate to harsh conditions. Together with a robust Cast Iron frame, the motor delivers reliable operation in dusty or humid facilities, reducing maintenance frequency and extending service life in industrial settings.
Yes, the motor carries CE compliance, aligning with European safety and performance standards. It is well-suited for conveyors, pumps, and fans in process or manufacturing lines where duty is S1 (continuous) and reliability is critical for uptime and energy efficiency.
Key specs include a 2-pole design with a 280 frame, IMB5 IM3001 mounting classes, IP55 protection, and IC411 insulation. The unit weighs around 665 kg net (685 kg gross) and is configured for ambient conditions up to 40 °C at elevations up to 1000 m, making it suitable for many industrial sites.
The Cast Iron frame and robust insulation reduce wear and downtime, lowering maintenance costs. The motor’s compatibility with standard drives and its reliable performance support energy efficiency and longer service intervals, delivering meaningful total cost of ownership improvements for manufacturing lines and OEM upgrade programs.
