西门子贝得电机变频应用Converter fed
application
当变频器驱动电动机时,电磁干扰的程度大小取决于变
频器的类型(种类,IGBT 数量,干扰控制措施及制造商)、
布线、距离以及应用需求。在设计和应用阶段必须参考
变频器制造商关于电磁兼容性的安装指导。
当 1TL0 电动机变频应用(变频器供电),且输出额定功
率时,电动机的使用温度等级为 155(F)。为了避免杂
散电流对电动机轴承的损坏,推荐 FS250 ~ 355 电动机使
用绝缘轴?#23567;?#35831;向西门子咨询关于绝缘轴承的详细信息。
当负载转矩在?#24066;?#30340;转矩?#27573;?#20869;时,电动机能够自扇冷
In application where the motor is driven by a converter,
the degree of electrical interference depends on the type
of converter used (type, number of IGBTs, interference
suppression measures, and manufacturer), cabling, distance
and application requirements. The installation guidelines of
the converter manufacturer with regards to electromagnetic
compatibility must be considered at all times during the
design and implementation phases.
At rated output with converter fed operation, the motors will
be used in temperature class 155 (F). To prevent damage
as a result of bearing currents, insulated bearings are
recommended to be assembled for frame size 250 and above.
Please inquire Siemens about the detailed information of
insulated bearing.
1TL0 电动机适于变转速、恒转速的各种应用,如风机、泵、
压缩机、纺织机械?#21462;?br /> 1TL0 电动机的标准绝缘系统设计要求,能够保证其在变
频器供电电压不超过 460 V 时正常运行。
1TL0 motors are suitable for pumps, fans, compressors,
texitle machine and mechanical machine applications where
variable or constant speed is required.
The standard insulation of the 1TL0 motors is designed such
that operation is possible on the converter at mains voltage up
to 460 V.

注: 风扇可以在 210 ~ 240VD/360 ~ 420VY 50Hz 电源供电下运行,也可以在 220 ~ 260VD/380 ~ 480VY 60Hz 电源供电下运行。其他电源供电,须
特殊询价。
Note: The fan can be running with supply 210 ~ 240VD/360 ~ 420VY 50Hz, and also 220 ~ 260VD/380 ~ 480VY 60Hz. Other voltage supply, possible on
request.

却;当负载转矩超过所?#24066;?#30340;转矩时,电动机需要强迫
冷却。
在电动机运行速度超过额定转速时,噪声和振动值将增
加,并且轴承的寿命将缩短。需要注意再润滑周期和润
滑脂的寿命。
By usage with admissible torque and below, the motor can
be operated with self cooling; by usage over the admissible
torque line, the motor with forced ventilation is needed.
At operating speeds above rated speed the noise and
vibration levels increase and the bearing life time reduce.
Attention should be paid to the re-greasing intervals and the
grease service life.
