Description
This standard covers the minimum requirements for form-wound and bar-wound brushless synchronous machines 500 kVA and larger for use in petroleum, chemical, and other industrial applications. This standard includes synchronous motors and generators with two different rotor designs:
a) salient-pole type rotors with solid or laminated poles;
b) cylindrical type rotors with solid or laminated construction.
Notes following a paragraph in Section 1 through Section 8 are informational only and are not enforceable as part of this standard.
Some paragraphs have intentionally been left blank to align paragraph numbers with API 541.
A round bullet (・) at the beginning of a paragraph indicates that either a decision is required or further information is to be provided by the purchaser. This information shall be indicated on the datasheets (see Annex A or Annex B); otherwise, it shall be stated in the quotation request or in the order.
A diamond bullet (◆) at the start of a paragraph indicates additional requirements for motors applied with an adjustable speed drive (ASD).
The purchaser specifies machine details and features by completing the associated sections of the datasheets in Annex A or Annex B.
NOTE Guidance for completion of the datasheets is provided in Annex D and Annex E.
The vendor completes the details and features in the vendor section of the datasheets (see Section 8 and Annex A or Annex B).
Within this standard, the term “motor” addresses synchronous motors as well as synchronous motor-generators that are subjected to an asynchronous start. The term “machine” addresses the three types of machines: motors, generators, and motor-generators.
Super synchronous motor applications are addressed in Annex I.
