IEC 60034-1-A1-A2-EN-Rotating Electrical Machines

This part of IEC , together with part 1, gives the requirements for a. IEC standards may have multiple sub-part documents; only the main title for the standard is listed here. This publication does not apply to voltages representing or transmitting signals or measured values. International Standard IEC defines a set of standard voltages for use in low voltage and high voltage AC electricity supply systems.

Make a suggestion. Note 1 to entry: The value for the rated voltage of high voltage equipment is generally assigned from the list of highest voltages for equipment in Tables 3, 4 and 5 of IEC The IEC shall not be held responsible for identifying any or all such patent rights. System IEC This sixth edition supersedes the fifth edition of IEC , and now includes standard voltages below V a.

Low voltage. At the same time, with the IEC standard, a new procedure for the measurement of efficiency has been introduced which also contributes to international harmonization. The standard is in four volumes, which describe general requirements, fuses for industrial and commercial applications, fuses for residential applications, and fuses to protect semiconductor devices. You can also select the units and symbols appropriate for the selected standard. Overvoltage cat. Part 1: Frame size 56 to and flange size 55 to Table 4 shows nominal voltages above 35 kV and not exceeding kV.

If you are involved with working with motors, this table is very important and could be used as a reference as to what area of AC motors the various units of the standard covers: The table below gives an overview of standards in relation to design, production and use of electric motors. The IEC enables global trade in electronics and electrical goods. Information relating to this publication, including its validity, is available in the IEC Catalogue of publications see below in addition to new The new standard IEC is to replace the different national systems. In the previous note we looked at the approach taken by the standard to the sizing of cables and illustrated this with an example.

Currently, the safety principles of IEC series, IEC , series and IEC are the fundamentals of most electrical standards in the world see table below. Edition 7.

Description:

Specifies allowable tolerances for efficiency, power factor, speed, locked rotor torque, pull out torque, starting current and moment of inertia. Since that date, electrical supply companies have generally tried to meet the requirements of the standard but there is no mandatory requirement for them to do so. Rated operational voltage. The battery swap system is intended to be connected to the supply network.

IEC ed5. IEC E deals with the safety of electric heat pumps, including sanitary hot water heat pumps, air-conditioners, and dehumidifiers incorporating motor-compressors and hydronic room fan coils, their maximum rated voltages being not more than V for single phase appliances and V for all other appliances. Appliances not intended for normal household use but which nevertheless may be a source of danger to the public, such as appliances intended to be used by laymen in shops, in light industry and on farms, are within the scope of this standard.

This standard also applies to electric heat pumps, air conditioners and dehumidifiers containing flammable refrigerant. Flammable refrigerants are defined in 3. The appliances referenced above may consist of one or more factory made assemblies. If provided in more than one assembly, the separate assemblies are to be used together, and the requirements are based on the use of matched assemblies.
