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/MN | 2.4 | 2.6 | 2.8 |
