ABB Low Voltage M2BAX 355kW 3-phase ac induction Motors asynchronous

Product Application

Standards
ABB motors are of the totally enclosed, three phase squirrelcage type, built to comply with international IEC andEN standards. Motors conforming to other national andinternational specifications are also available on request.All production units are certified to ISO 9001 internationalquality standard as well ISO 1 4OO0 environmental standardand conformto all applicable EU Directives.
Voltage and Frequency
The impact on temperature rise caused by voltage andfrequency fluctuation is defined in lEC 60034-1.The standard divides the combinations into two zones, zoneA and B. Zone A is the combination of voltage deviation+/-5% and frequency deviation +/-2%. Zone B is thecombination of voltage deviation +/-1O% and frequencydeviation +3%/-5%.The motors are capable of supplying the rated torque in both zone A and B, but the temperature rise will be higher than atrated voltage and frequency. The motors are to be inoperation only for a short period of time in zone B.
Rated output
M2BAX motors rated outputs means that the motor runs undercontinuous duty S1 (IEC 60034-1) operation at ambient temperature from -20C ~40°C and at altitudes of up to 1000 mabove sea level.
Environmental
In accordance with IEC 60034-1, tolerance is the maximum allowed deviation betweenthe test result andthe declared value on the rating plate (orin the catalog).Test results are basedon test procedures in accordancewith IEC 60034-2-1,IEC 60034-9, and IEC 60034-12.
Overload time
According to IEC 60034, M2BAX motors are designed towithstand overload capacity of 1.5 times rated current for2 minutes at rated voltage and frequency.
Ambient temperatures and high altitudes
Normal motors are designed for operation at a maximumambient temperature of 40°C and at a maximum altitude of1000 meters above sea level.If a motor isoperated at higher ambient temperatures or altitude, it should be derated.
