风机型电动机组启动时间的分析与建议

Analysis and Comments on Startup Time of Fan Type Motor

风机型电动机组启动时间一般较长 ,对电动机定子、转子导体温升不利。应根据风机型电动机组启动时的实际工况确定启动时间 ,以此核算电动机定子、转子导体温升是否超过允许值 。

The startup time for the fan type motor is relatively longer, which is unfavorable to the temperature rise of its stator and rotor conductors. It is necessary to determine its startup time according to the actual conditions of the motor group during start and check whether the temperature rise of the stator and rotor conductors exceed the limit. Some startup time given by certain information will not be recommended.
