Overview
EN 60034-8:2007/A1:2014 (IEC 60034-8:2007/A1:2014) is a CENELEC/IEC amendment that clarifies and updates requirements for terminal markings and direction of rotation of rotating electrical machines. This Amendment 1 was approved by CENELEC on 24 April 2014 and updates Part 8 of the IEC 60034 series, which establishes standardized identification of machine terminals and the convention for indicating rotation. The amendment specifically refines provisions for synchronous machines, including field winding terminal designations and guidance for permanent magnet machines.
Key topics and technical requirements
- Scope: Terminal markings and direction of rotation for rotating electrical machines (general applicability across machine types).
- Amendment highlights for synchronous machines:
- Primary windings: Terminal markings for synchronous machine primaries are to follow the conventions established for asynchronous machines.
- Field winding (d.c. separately excited): Terminal markings shall be F1 and F2 for separately excited dc field windings.
- Permanent magnet machines: Because there is no separate excitation, terminal markings for permanent magnet machines shall follow those established for asynchronous machines. This applies to machines driven by adjustable frequency drives (AFD) and to machines intended for across-the-line start, including designs with permanent magnets in/on the rotor with or without a squirrel-cage starting rotor.
- Direction of rotation: The standard defines the convention for indicating rotation direction (as part of Part 8), ensuring consistent labelling across equipment and documentation.
- Administrative details: Amendment 1 was incorporated into the European standard without modification and contains implementation timelines for national adoption.
Practical applications
- Ensures consistent terminal identification on motors and generators for installation, maintenance, testing, and documentation.
- Reduces wiring errors and improves safety by standardizing markings (especially important for multi-terminal synchronous machines and machines with dc field windings).
- Supports integration of permanent magnet motors with AFDs and traditional starters by clarifying terminal marking expectations.
- Useful for manufacturers, motor repair shops, test laboratories, and specifying engineers who need consistent terminal and rotation information for procurement, installation, and commissioning.
Who should use this standard
- Motor and generator manufacturers for product marking and documentation
- Electrical design engineers and panel builders for correct wiring and control schematics
- Maintenance personnel and installation contractors for safe connection and reversing procedures
- Test labs and certification bodies ensuring compliance with EN/IEC machine marking rules
Related standards
- IEC/EN 60034 series (general standard for rotating electrical machines)
- Other parts of IEC 60034 addressing performance, testing, and mounting that complement terminal/rotation markings

The SIST EN 60034-8:2007/A1:2014 standard plays a crucial role in the domain of rotating electrical machines by providing clear and comprehensive guidelines in several key areas. Its scope encompasses both alternating current (a.c.) and direct current (d.c.) machines, ensuring that users can identify winding connection points with accuracy. This standard specifies essential rules for the marking of winding terminals, facilitating consistent and reliable identification in various applications. One of the primary strengths of this standard is its detailed specification regarding the direction of rotation, which is vital for the proper functioning of electric machines. By establishing a relationship between terminal markings and direction of rotation, it enhances operational safety and efficiency in machine applications. The inclusion of terminal markings for auxiliary devices is another significant aspect, as it supports seamless integration and connection within complex systems. Furthermore, the provision of connection diagrams for common applications serves as a practical tool for manufacturers and technicians, making it easier to implement the standards in real-world scenarios. The clarity and precision of these diagrams contribute to reducing installation errors and promoting uniformity in the industry. While the standard effectively covers a wide range of rotating electrical machines, it explicitly excludes turbine-type synchronous machines, which may limit its applicability in certain specific contexts. However, this targeted approach allows for more focused and relevant guidelines tailored to the majority of a.c. and d.c. machines. Overall, the SIST EN 60034-8:2007/A1:2014 standard is a valuable resource that enhances operational consistency, safety, and efficiency in the field of electrical engineering. Its detailed provisions regarding terminal markings, connection points, and direction of rotation underscore its relevance in ensuring the effectiveness of rotating electrical machines across various applications.
