Content:
components not as a part of the insulation system. Sec. 5.8, Motor Lead Cable, Motor lead cable is not normally considered part of the motor or motor insulation system. Specific qualification guidance was provided in this section to address motor lead cables. Sec. 5.9, Bearings, This section specifically addresses bearings and their relation to the motor qualification. DG-1150, Page 4 Sec. 5.10, Lubricants, This section specifically addresses lubricants and their relation to the motor qualification. Sec. 5.11, Seals and Gaskets, This section specifically addresses seals and gaskets and their relation to the motor qualification. Sec. 5.12, Accessories, This section specifically addresses items such as space heaters, temperature detectors, and vibration detectors and their relation to the motor qualification. Sec. 5.13, Equipment Boundary and Interfaces, This section addresses defining boundaries for motor accessory and/or driven equipment for seismic qualification. Exception 2: Qualification tests should simulate as close as practicable all design basis events... Sec. 3.3, Components, IEEE 334-2006 added the definition of component which includes some items that are considered “auxiliary equipment” such as thermal overload relays, instrument sensors, seals, sight glasses, etc. The intent of providing a specific definition of “components” as related to motors was to include these types of auxiliary equipment. The configuration of the test specimen is the qualifiers responsibility. When the standard states “motor”, the intent is that any given motor may include various components/ auxiliary equipments. Therefore, when the standard states “motor”, the intent is that the motor specimen should include any applicable auxiliary equipment. Sec. 5.1.3, Motor Performance, This section states that the qualification program shall demonstrate that the motor (inclusive of auxiliary equipment per Sec. 3.3) is able to start, accelerate to operating speed and operate
