HEV PMSM驱动测试线束
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)驱动器的测试线束。当以给定的速度和扭矩运行时，测试线束可用于确定总体驱动损失。Simscape™Electrical™Motor & Drive (System Level)模块可以使用该测试线束的表列损耗信息，快速模拟完整的驱动周期，同时仍能准确预测整体系统效率。

scope和Simscape日志的模拟结果
下面的第一个图显示了Spectrum Analyzer的结果。第二幅图显示了测量和命令的转子速度。绕组电流也被绘制，这解释了高频纹波在电机速度。
下表显示了ee_pmsm_drive模型中各个组件耗散的功率。这些总数是使用已记录的Simscape变量和损失计算工具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。
