IEC 61800-3 specifies electromagnetic compatibility (EMC) requirements for adjustable speed power drive systems (PDSs) and machine tools (MTs). A PDS is an AC or DC motor drive including an electronic converter. Requirements are stated for AC and DC PDSs and MTs with input or output voltages (line-to-line voltage), up to 35 kV AC RMS. IEC 61800-3 applies to equipment of all power ratings. As a product EMC standard, IEC 61800-3 can be used for the assessment of PDS and MT. It can also be used for the assessment of complete drive modules (CDM) or basic drive modules (BDM).
Traction applications and electric vehicles are excluded. Equipment which is defined as group 2 in CISPR 11:2015 is excluded. IEC 61800-3 does not give requirements for the electrical machine which converts power between the electrical and mechanical forms within the PDS. Requirements for rotating electrical machines are covered by the IEC 60034 series. In IEC 61800-3, the term "motor" is used to describe the electrical machine, whether rotary or linear regardless of the direction of power flow.
IEC 61800-3 applies to BDMs, CDMs, PDSs and MTs with or without radio function. However, this document does not specify any radio transmission and reception requirements. IEC 61800-3 defines the minimum requirements for emission and immunity in the frequency range from 0 Hz to 400 GHz. Tests are not required in frequency ranges where no requirements are specified.
This edition includes the following significant technical changes:
— extension of the scope to machine tools with one or more embedded PDS,
— an extension of the frequency range for radiated immunity tests to 6 GHz,
— general updates in the normative part and the informative annexes.
The text of IEC 61800-3:2022 has been approved in Europe as EN IEC 61800-3:2023 without any changes.
