General Information
Frequently Asked Questions
WG 27 is a Technical Committee within the International Electrotechnical Commission (IEC). It is named "TC 9/WG 27". This committee has published 8 standards.
WG 27 develops IEC standards in the area of Information technology. Currently, there are 8 published standards from this technical committee.
The International Electrotechnical Commission (IEC) is the world's leading organization for the preparation and publication of international standards for electrical, electronic, and related technologies. Founded in 1906, the IEC provides a global platform for companies, industries, and governments to meet, discuss, and develop the international standards they require.
A Technical Committee (TC) in IEC is a group of experts responsible for developing international standards in a specific technical area. TCs are composed of national member body delegates and work through consensus to create standards that meet global industry needs. Each TC may have subcommittees (SCs) and working groups (WGs) for specialized topics.
Applies to the combinations of motor(s), chopper and their control, and its object is to specify a)the performance characteristics of electric drives consisting of a chopper, direct current motors, and the related control system b)methods of verifying these performance characteristics by tests. In traction drives, a combined system with chopper and direct current motor(s) without any control between the mechanical output and the chopper is not usual. It is not, therefore, considered in this standard. IEC 60349-1 applies to chopper-fed direct current motors, IEC 61287-1 to power electronic convertors, and IEC 60571 to electronic equipments. As a consequence, IEC 60349-1 describes the tests to demonstrate the compliance of the motor to its specification, while IEC 61287-1 does the same for the chopper.
