HEV永磁同步电机驱动试验线束

开放模式

这个例子展示了一个用于典型混合动力汽车的永磁同步电机(PMSM)驱动的测试线束。测试线束可用于确定在给定速度和扭矩下运行时的总体驱动损失。然后，Simscape™Electrical™马达和驱动器(系统级)块可以使用该测试束的表格损失信息，快速模拟完整的驱动周期，同时仍然准确预测总体系统效率。

范围和Simscape日志的模拟结果

下面的第一个图显示了频谱分析仪的结果。第二个图显示测量和命令转子速度。绕组电流也被绘制出来，这解释了电机转速的高频波动。

下表显示了ee_pmsm_drive模型中各个组件消耗的功率。这些总数是使用记录的Simscape变量和损失计算实用程序ee_getPowerLossSummary从模拟结果中计算出来的。总输出功率在负载，以及损失显示。

运行PMSM驱动测试线束模型生成仿真数据，当转速= 1400rpm，扭矩= 200Nm时，效率= 85.9726%，各部件的瓦损失如下:FEM_Parameterized_PMSM'} 3609.5 {'ee_motor_pmsm_drive. three_phase_逆变器. switch2。IGBT'} 158.6 {'ee_motor_pmsm_drive. three_phase_逆变器. switch3 .
