Scope
JB/T 6741-2013 is the English-translated version of YSD系列变极双速三相异步电动机.
JB/T 6741-2013 is a recommended machinery industry standard of China for the YSD series of two-speed, pole-changing three-phase asynchronous motors.
It sets the types of the series, its basic parameters and dimensions, the technical requirements, the test methods and the inspection rules, together with requirements for marking, packaging, transport and storage.
The document therefore serves as the product specification for motors of this series. It quotes a number of quoted standards, among them GB 755-2008, GB/T 1032-2005, GB/T 2828.1-2012, GB/T 4772.1-1999, GB/T 4942.1-2006, GB/T 5171-2002 and GB/T 10069.1-2006.
It supersedes JB/T 6741-1993. The classifications recorded are K22 in the Chinese scheme and 29.160.30 internationally, under the Ministry of Industry and Information Technology.
