Brushless Synchronous Machines—500 kVA and Larger

active, Most Current
Organization: API
Publication Date: 1 May 2022
Status: active
Page Count: 269
scope:

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.
