About This Item
P841/D4, July 2019 is a technical standard focused on cooled, totally enclosed fan-cooled (TEFC) squirrel cage induction motors rated up to and including 370 kW (500 hp). It is relevant to motor design, performance, and application expectations where dependable operation and controlled thermal behavior matter. For engineers, buyers, and compliance teams, this document helps define a common basis for evaluating medium- to larger-size motors used in industrial and energy-related equipment.
What is P841/D4, July 2019?
P841/D4, July 2019 addresses the technical requirements associated with cooled TEFC squirrel cage induction motors within the stated power range. The document is aimed at giving a consistent reference for motor characteristics that may affect selection, testing, and specification. In practice, it supports more uniform expectations for construction, ratings, and performance-related considerations. This makes the standard useful when comparing products or confirming that a motor meets the intended engineering criteria.
Where is P841/D4, July 2019 used?
This standard is typically used where TEFC squirrel cage induction motors are applied in demanding industrial systems, including pumps, compressors, conveyors, fans, and similar driven equipment. Its scope also aligns with power, energy, and industry applications where motor reliability and thermal management are important. In projects involving geoscience or process-related installations, P841/D4, July 2019 may help define a consistent procurement and verification basis for motor performance and enclosure-related expectations.
Why is P841/D4, July 2019 important?
P841/D4, July 2019 matters because motor specifications need to be clear, comparable, and technically grounded. By providing a shared reference for cooled TEFC squirrel cage induction motors, it can help reduce ambiguity in design reviews, purchasing decisions, and acceptance checks. That supports better consistency across installations and may lower the risk of mismatched performance, overheating concerns, or unnecessary rework. For organizations managing equipment reliability, it offers a practical basis for standardization.
