BS EN IEC 60034-4-1:2018适用于额定功率为1 kVA且 更大的。大多数方法适用于带有励磁绕组的机器 滑环和刷子的供应。无刷励磁同步电机 有些测试需要特别的努力。对于具有永磁励磁的机器， 所述试验的适用性有限，应采取特殊预防措施 防止不可逆退磁。 交叉引用:IEC 60034-2-1IEC 60051（所有部分）IEC 60034-1:2017IEC 60050-411:1996购买本文件时可用的所有现行修订版均包含在购买本文件中。

BS EN IEC 60034-4-1:2018 applies to three-phase synchronous machines of 1 kVA rating and larger.Most of the methods are intended to be used for machines having an excitation winding with slip-rings and brushes for their supply. Synchronous machines with brushless excitation require special effort for some of the tests. For machines with permanent magnet excitation, there is a limited applicability of the described tests, and special precautions should be taken against irreversible demagnetization.Cross References:IEC 60034-2-1IEC 60051 (all parts)IEC 60034-1:2017IEC 60050-411:1996All current amendments available at time of purchase are included with the purchase of this document.
