贝得西门子电机的电气特性
额定输出
1TL0电动机的额定功率是指电动机在连续运行的情况
下 S1(IEC 60034-1),此时周围环境温度为 -15 oC ~ 40
oC,海拔高度不超过 1000 m。
电压、频率
IEC 60034-1 将电压和频率的偏差分为 A 类(电压偏差
±5 %,频率偏差 ±2 %)和 B 类(电压偏差 ±10 %,频
率偏差 +3 % / -5 %)。电动机均能够在 A 类和 B 类提供
额定转矩。在 A 类中,温度比正常运行下温度大约提升
10 K。
Electrical design
Rated Output
1TL0 motors rated output powers means that the motor runs
under continuous duty S1 (IEC 60034 - 1) operation when
operated at ambient temperature from -15 oC to 40 oC and at
altitudes of up to 1000 m over sea.
Voltage and Frequency
IEC 60034-1 differentiates between Category A (combination
of voltage deviation ±5 % and frequency deviation ±2
%) and Category B (combination of voltage deviation
±10 % and frequency deviation +3 % / -5 %) for voltage
and frequency fluctuations. The motors can supply their
rated torque in both Category A and B. In Category A, the
temperature rise is approximately 10 K higher than during
normal operation.
