GOST R 52776-2007 PDF

Full title and description

GOST R 52776-2007 — "Rotating electrical machines. Rating and performance" (Russian: "Машины электрические вращающиеся. Номинальные данные и характеристики"). The standard is a national adoption/modification of IEC 60034‑1 (2004) and sets requirements for nominal values, ratings and performance characteristics of rotating electrical machines (motors and generators).

Abstract

This standard defines the nominal data and performance characteristics for rotating electrical machines of various types and duty cycles. It establishes nameplate ratings, nominal voltages and powers, duty types (S1–S10), permissible deviations of voltage and frequency, basic test and rating principles and references to relevant safety, electrical and mechanical requirements. The document incorporates requirements from IEC 60034‑1:2004 and was intended as the national reference for rating and performance in the Russian Federation until later editions/adoptions superseded it.

Scope

The standard applies to rotating electrical machines of both alternating and direct current types (except where other specific standards apply) and covers the establishment of nominal values, nameplate information, rating conventions and basic performance characteristics. It is intended for use in design, testing, selection and procurement of motors, generators and rotating machines, and to harmonize Russian practice with the corresponding IEC 60034‑1 requirements.

Key topics and requirements

• Definitions of nominal (rated) values for voltage, current, power, speed and frequency.
• Classification of duty types (S1–S10) and rules for determining rated output for each duty type.
• Requirements for nameplate data and presentation of rated parameters.
• Permissible deviations of supply voltage and frequency (zones A and B) and related performance expectations.
• Rules for machines with multiple nominal data (multispeed/multi-rating machines).
• Reference to insulation classes, thermal limits and allowable temperature rises.
• Normative references and alignment with IEC 60034‑1:2004 and related GOST/GOST‑R standards for safety and testing.

Typical use and users

Manufacturers of electric motors and generators, testing laboratories, certification bodies, design engineers, equipment purchasers and facilities maintenance teams use this standard to specify and verify rated performance and nameplate information. It is also used by procurement and regulatory specialists when assessing conformity of rotating machines to national technical requirements.

Related standards

Normative and related documents include IEC 60034 series (notably IEC 60034‑1), subsequent national adoptions such as ГОСТ IEC 60034‑1‑2014 (and later revisions), and a range of GOST/GOST‑R standards covering insulation, environmental conditions (GOST 15150), electromagnetic compatibility and electrical safety (for example, GOST R МЭК 60204‑1). The standard itself cites multiple GOST/GOST‑R normative references used in machinery testing and safety.

FAQ

Q: What is this standard?

A: GOST R 52776‑2007 is the Russian national standard titled "Rotating electrical machines. Rating and performance" that sets rules for nominal values, rating and performance of rotating electrical machines (based on IEC 60034‑1:2004).

Q: What does it cover?

A: It covers nominal (rated) data, nameplate information, duty classifications (S1–S10), rated output definitions, permissible voltage/frequency deviations and related performance expectations, and references to tests and safety requirements for rotating machines.

Q: Who typically uses it?

A: Motor and generator manufacturers, test laboratories, certification bodies, design and application engineers, procurement specialists and maintenance personnel use it to specify and verify machine ratings and performance.

Q: Is it current or superseded?

A: GOST R 52776‑2007 has been withdrawn/cancelled for national use and has been superseded on the Russian corpus by national adoptions of the IEC document (for example, ГОСТ IEC 60034‑1‑2014 and later revisions). Records indicate the standard ceased to be effective (end of validity) in 2016 and was replaced by later GOST IEC editions. Users should reference the current GOST IEC 60034‑1 edition in force for up‑to‑date requirements.

Q: Is it part of a series?

A: Yes. It corresponds to Part 1 of the IEC 60034 series (rating and performance) and is related to other parts of the IEC 60034 family covering vibration, efficiency, testing methods and other topics for rotating electrical machines. National GOST adoptions mirror the IEC parts as separate or consolidated GOST/ГОСТ IEC documents.

Q: What are the key keywords?

A: Rotating electrical machines, rating, performance, nominal values, nameplate, IEC 60034‑1, motors, generators, duty types (S1–S10).
