BS EN 60349-4:2013

What is BS EN 60349-4 - Permanent magnet synchronous electrical machines connected to an electronic converter about?

BS EN 60349 is a European standard on electric traction that discusses rotating electrical machines for rail and road vehicles. BS EN 60349-4 is the fourth part of the series that applies to converter-fed permanent magnet synchronous motors or generators (machines) forming part of the equipment of electrically propelled rail and road vehicles to ensure that the combined unit meets the requirements.

BS EN 60349-4 is derived from IEC 60349-2 changing the subject to permanent magnet synchronous machines.

The object of BS EN 60349-4 is to enable the performance of a machine to be confirmed by tests and provide a basis for assessment of its suitability for a specified duty and comparison with other machines.

Where further testing is to be undertaken by a combined test, it may be preferable, that some type and investigation tests be carried out on the combined testbed, to avoid duplication.

 The machines covered by BS EN 60349-4 are classified as follows:

• Traction motors - Motors for propelling rail or road vehicles
• Main generators - Generators for supplying power to traction motors on the same vehicle or train
• Auxiliary motors not covered by IEC 60034 - Motors for driving compressors, fans, auxiliary generators, or other auxiliary machines
• Auxiliary generators not covered by IEC 60034 - Generators for supplying power for auxiliary services such as air conditioning, heating, lighting, battery charging, etc

BS EN 60349-4 also applies to machines installed on trailers hauled by powered vehicles.

Note1: The basic requirements of BS EN 60349-4 may be applied to machines for special purpose vehicles such as mine locomotives but BS EN 60349-4 does not cover flameproof or other special features that may be required.

Note2: It is not intended that BS EN 60349-4 should apply to machines on small road vehicles, such as battery-fed delivery vehicles, factory trucks, etc. BS EN 60349-4 also does not apply to minor machines such as windscreen wiper motors, etc. that may be used on all types of vehicles.

Who is BS EN 60349-4 - Permanent magnet synchronous electrical machines connected to an electronic converter for?

BS EN 60349-4 on permanent magnet synchronous electrical machines connected to an electronic converter for railways is useful for:

• Manufacturers of permanent magnet synchronous electrical machines and related components for railways
• Technical and Maintenance staff for railways
• Test centres
• Regulatory authorities

Why should you use BS EN 60349-4 - Permanent magnet synchronous electrical machines connected to an electronic converter?

Permanent magnet synchronous electrical machines connected to an electronic converter collaborate to produce all the technical information necessary to meet the requirements. The converter designer also provides the machine designer with the characteristics showing, for example, the converter line-to-line output voltage (including the repetitive voltage peaks), current, fundamental frequency, harmonics, and power over the whole range of the application, including operation at the maximum and minimum values of the contact-system voltage.

BS EN 60349-4 guideline assists you with environmental conditions, characteristics, marking, type tests, reduced type tests, routine tests, investigation tests, temperature-rise tests, characteristic tests, and tolerances for permanent magnet synchronous electrical machines connected to an electronic converter used in railways.

With obedience and compliance to BS EN 60349-4, you can standardise the functioning of permanent magnet synchronous electrical machines connected to an electronic converter. The tests provided also guide you in properly assessing the converter and machine to produce reliable results.
