About This Item
P841.1/D6, Aug 2023 is a technical standard focused on International Energy Efficient Class 3 (IE3) premium-efficiency, severe-duty, totally enclosed frame surface cooled squirrel cage induction motors rated from 0.75 kW to 370 kW (1 hp to 500 hp). It addresses motor performance and construction expectations for industrial power applications, where efficiency, durability, and enclosure design matter. For engineers, specifiers, and procurement teams, this document helps define a clearer basis for selection, testing, and conformity.
What is P841.1/D6, Aug 2023?
P841.1/D6, Aug 2023 is a standards document that sets out technical requirements for a defined class of three-phase induction motors used in demanding service conditions. Its scope centers on IE3 premium-efficiency machines with severe-duty construction and totally enclosed, frame-surface-cooled designs. In practice, the standard is relevant to motor ratings, performance expectations, and design features that support reliable operation. As an inactive draft document, it is best used as a reference for understanding the intended engineering framework behind this motor category.
Where is P841.1/D6, Aug 2023 used?
This standard is most relevant in industrial power systems that rely on robust induction motors for continuous or heavy-duty operation. Typical use cases may include pumps, fans, compressors, conveyors, process lines, and other equipment that benefits from premium-efficiency motor performance. Because it covers a wide power range from 0.75 kW to 370 kW, it can apply to both smaller machine drives and larger plant equipment. P841.1/D6, Aug 2023 is especially useful where enclosed cooling and severe-duty construction are important.
Why is P841.1/D6, Aug 2023 important?
This standard matters because it gives buyers and engineers a common technical basis for specifying efficient industrial motors with predictable construction and performance characteristics. Using P841.1/D6, Aug 2023 can support clearer procurement comparisons, more consistent design decisions, and better alignment between motor ratings and application demands. It may also help reduce risk when evaluating compliance, insulation, enclosure suitability, and thermal behavior in service. For equipment owners, that consistency can improve long-term reliability and simplify technical review.
