1 Scope

GB/T 13958-2022 is the Chinese national standard on test methods for small power permanent magnet synchronous motors, in the field of electrical engineering. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 30 December 2022 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 July 2023. Classification: ICS 29.160.01, CCS k20. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This document describes the basic requirements of small power permanent magnet synchronous motor test, test preparation, temperature rise test, efficiency measurement, stall test and other test items. This document applies to permanent magnet synchronous, hysteresis synchronous and reluctance synchronous low-power synchronous motors without DC excitation windings (self-starting, not run with the controller). This document does not apply to electromagnetic deceleration permanent magnet synchronous motors and synchronous motors with DC field windings.
