EUROLAB laboratory provides testing and compliance service within the scope of IEC 60034-8 standard. The revision of this part of IEC 60034 provides worldwide uniformity in electrical connections for rotating electrical machines and applies the recommendations of the basic safety publication IEC 60445 in determining marking requirements.

IEC 60034-8 Rotating Electrical Machines, Part 8: Standard Test for Terminal Markings and Direction of Rotation

These standardized connections will then allow the safe replacement of electrical machinery with control and protective devices using standard terminal markings.

Applies to AC and DC machines and specifies the rules for defining winding connection points;

  • Marking of winding terminals;
  • direction of rotation;
  • Relationship between terminal markings and direction of rotation;
  • Terminal marking of auxiliary devices;
  • Connection diagrams of machines for common applications.

According to this standard, machines with terminal markings will have a clockwise rotation. For other configurations, including one-way machines, an arrow on the enclosure should indicate the direction of rotation.
