M2BAX motors rated outputs means that the motor runs under continuous duty S1 (IEC 60034-1) operation at ambient temperature from -20℃-40℃ and at altitudes of up to 1000m above sea level.
Voltage and Frequency
The impact on temperature rise caused by voltage and frequency fluctuation is defined in IEC 60034-1.
The standard divides the combinations into two zones, zone A and B. Zone A is the combination of voltage deviation +/-5% and frequency deviation +/-2%. Zone B is the combination of voltage deviation +/-10% and frequency deviation +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 at rated voltage and frequency. The motors are to be in operation only for a short period of time in zone B.
In accordance with IEC 60034-1, tolerance is the maximum allowed deviation between the test result and the declared value on the rating plate (or in the catalog).
Test results are based on test procedures in accordance with IEC 60034-2-1, IEC60034-9, and IEC60034-12.
According to IEC 60034, M2BAX motors are designed to withstand overload capacity of 1.5 times rated current for 2 minutes at rated voltage and frequency.
Ambient temperatures and high altitudes
Normal motors are designed for operation at a maximum ambient temperature or altitude, it should be derated. Detailed information, please contact your ABB sales office.
