起动次数

起动等级:6.150.300.600次(Z)/时

起动次数(Z)换算:

一次点动(即一次不完全的起动,在该过程中电动机的速度不超过1/4额定转速)的热等效当量为0.25次全起动

一次电制动(制动到1/3额定转速)的热等效当量为0.8次全起动.

一次逆转的热等效当量为1.8次全起动.起动等级典型示例,见表2

惯量率

启动次数的单位常用FI·Z表示,其中FI为传动系统的惯量率,即:

式中:Jm--电动机转子的惯量;
Jext--折算到电动机轴上的被拖动机械的惯量。

计算示例:

有一台YZR;315M-6电动机,已知其用于S4-40%工作制时;对应于输出功率75kw的FI·Z值300,已知折算到电动机轴上的被拖动机械的惯量Jext为7.7kg·m2,求实际可用的启动次数。

从表4查的YZR2315M-6的转子惯量Jm为6.4kg·m2,则:

从而每小时实际可用启动次数(Z)为:

转矩:

基准工作制时,在额定电压和额定频率下最大转矩对额定转矩之比见表3

PNKW≤5.5>5.5~7.5>7.5
Mmax/MN2.42.6

定货须知:

1.定货时必须说明产品型号、额定功率、额定电压、额定频率、调速范围及在此范围内的运行特性,接线盒位置等。

2.如有特殊要求,经双方协商后,可提供其他极数,其他结构及安装型式的电动机,也可配带各种转感器(测速发动机、超速开关=编码器等),各种制动器(电磁式、涡流式)各种热敏保护装置和加热带等。
