Is IEC 60034 30?

IEC 60034-30 specifies energy-efficiency classes for single-speed, continuous duty(S1), three-phase, cage-induction motors with 2, 4 or 6 poles. It classifies three classes: IE1 (standard), IE2 (high) and IE3 (premium). For each class the efficiency is defined for a rated output range from 0.75 to 375 kW.

Is IEC 60034?

IEC 60034-1:2022 is applicable to all rotating electrical machines, except rotating electrical machines for rail and road vehicles, which are covered by the IEC 60349 series of standards.

What is bs en 60034?

BS EN 60034. 2. 1999. Methods for determining losses and efficiency of rotating electrical machinery from tests (excluding machines for traction vehicles)

What is IE4 efficiency?

IE4 represents the highest energy efficiency whilst IE1 represents the least energy efficiency. In other words, the higher the class number, the higher the motor efficiency. IE5 is to be incorporated in the next edition of IEC 60034-30-1, with a goal to obtain an energy loss reduction of 20% relative to IE4.

What is IP code in rotating machine?

The dust-resistance and waterproofing degrees of protection for the equipment are classified according to EN 60529 (Specification Degrees of Protection Provided by Enclosures (IP Code)) (=IEC 60529), EN 60034-5 (Rotating Electrical Machines – Part 5: Degrees of Protection Provided by The Integral Design of Rotating …

Is 4722 a standard?

This standard specifies the methods of measurements and the limits of temperature-rise for rotating electrical machines of all types covered by IS 4722 : 1968. The standards given in Annex A are necessary adjuncts to this standard.

What is meant by IEC standards?

The International Electrotechnical Commission (IEC) authors international standards for all electrical, electronic and related technologies. This standards collection addresses product development, performance, compatibility and related topics in order to ensure product compatibility and environmental safety.

What is the use of IEC?

An Importer -Exporter Code (IEC) is a key business identification number which mandatory for export from India or Import to India. No export or import shall be made by any person without obtaining an IEC unless specifically exempted.

What is routine test of motor?

The purpose of the test in the motor routine testing is to calculate power factor, starting current and starting torque. The test is done on the locked rotor condition. The starting current might be high, and the test normally is done at lower voltage and result of the test extrapolated to the rated voltage.

Is standard for electrical motor?

The dimensions of the motors shall be as specified in IS 1231, IS 2223 and IS 2254 as applicable. The method of measurement and the requirement Page 9 IS 12615 : 2011 4 shall be as given in 8.6 of IS/IEC 60034-1 and 5.7 of IS 15999 (Part 2/Sec 1).

What is IP rating of motor?

Ingress Protection Classification. Electric motor IP (ingress protection) classification is a measure of the capacity of the motor to resist ingress of dust and of water. Objects, dust, or water may enter the motor providing they cannot have any detrimental effect upon its operation. Two numbers follow the letters IP.
