These international standards have...

IEC 60034-30-1:2014 This standard defines four International Efficiency (IE) classes for single speed electric motors that are rated according to IEC 60034-1 or IEC 60079-0 (explosive atmospheres) and designed for operation on sinusoidal voltage.   – IE4 = Super premium efficiency – IE3 = Premium efficiency, identical to the table in 10CFR431 (‘NEMA Premium’) in the USA and CSA C390-10:2015 for 60 Hz – IE2 = High efficiency – IE1 = Standard efficiency   IEC 60034-30-1 covers the power range from 0.12 kW up to 1000 kW. Most of the different technical constructions of electric motors are covered...

General information Degrees of protection: IP code/IK code Classification of degrees of protection provided by enclosures of rotating machines are refers to: – Standard IEC 60034-5 or EN 60529 for IP code – Standard EN 50102 for IK code   IP protection Protection of persons against getting in contact with (or approaching) live parts and against contact with moving parts inside the enclosure. Also protection of the machine against ingress of solid foreign objects. Protection of machines against the harmful effects due to the ingress of water. IK code Classification of degrees of protection provided...

01 Safety margins per thermal class. ABB uses class F insulation, which, with temperature rise B, is the most common requirement among industry today.   The use of class F insulation with class B temperature rise gives ABB products a 25 °C safety margin. This can be used to increase the loading for limited periods, to operate at higher ambient temperatures or altitudes, or with greater voltage and frequency tolerances. It can also be used to extend insulation. For instance, a 10 K temperature reduction will extend the insulation life.   Thermal class 130 (B) – Nominal ambient temperature 40 °C...

General information Voltage and frequency 01 Voltage and frequency deviation in zones A and B. The impact on temperature rise caused by voltage and frequency fluctuation is defined in IEC 600341. The standard divides the combinations into two zones, A and B. Zone A is the combination of voltage deviation of +/-5 % and frequency deviation of +/-2 %. Zone B is the combination of voltage deviation of +/-10 % and frequency deviation of +3/-5 %. This is illustrated in figure below.   Motors are capable of supplying the rated torque in both zones A and B, but the temperature rise will be higher than...

Surface treatment The standard surface treatment of the Process performance motors is designed to meet corrosivity category C3, both outdoors and indoors. This also meets the requirements in C1 and C2.   The corrosivity categories are defined in standard ISO12944-2.   Atmospheric-corrosivity categories and examples of typical environments Corrosivity category The standard ABB paint color for motors is Munsell blue 8B 4.5/3.25, except for special systems such as NORSOK where a specific color is requested.   Examples of typical environments (informative only) Exterior Heated buildings with clean...
