IEC 60349-4:2012 applies to converter-fed permanent magnet synchronous motors or generators (machines) forming part of the equipment of electrically propelled rail and road vehicles. The object of this part is to enable the performance of a machine to be confirmed by tests and to provide a basis for assessment of its suitability for a specified duty and for compa-rison with other machines. Particular attention is drawn to the need for collaboration between the designers of the machine and its associated converter as detailed in this standard.

IEC 60349-1:2010 is applicable to rotating electrical machines, other than electronic converter-fed alternating current motors, forming part of the equipment of electrically propelled rail and road vehicles. The vehicles may obtain power either from an external supply or from an internal source. The object of this standard is to enable the performance of a machine to be confirmed by tests and to provide a basis for assessment of its suitability for a specified duty and for comparison with other machines. The main technical changes with regard to the previous edition are as follows:
- the limits valid for traction motors are now directly stated in this standard;
- the methods described in the relevant ISO standards are now allowed.

IEC 60349-2:2010 applies to converter-fed alternating current motors forming part of the equipment of electrically propelled rail and road vehicles. The object of this part is to enable the performance of a motor to be confirmed by tests and to provide a basis for assessment of its suitability for a specified duty and for comparison with other motors. The main technical changes with regard to the previous edition are as follows:
- the limits valid for traction motors are now directly stated in this standard;
- the methods described in the relevant ISO standards are now allowed.

IEC/TS 60349-3:2010 applies to machines complying with IEC 60349-2. The losses supplied at the fundamental frequency cannot be measured directly and so are derived from measurement of the fundamental frequency load current and the fundamental frequency no-load power input. The main technical changes with regard to the previous edition are corrections in some formulas in 3.2.1.2 and in Table A.2.
