Maximum torque per ampere (MTPA) is an optimization strategy for the control of electric motors and drives that employ field-oriented control (FOC), particularly with electric vehicles (EVs) and industrial automation applications. The goal of MTPA is to achieve the maximum possible torque output from a motor for a given current input.

操作培训
首先，点击屏幕右上角的Setup按钮，进入设定界面。我们以输入单元1为例，在<输入（基本）Input (Basic)>设置界面下，点击电压量程区域，会显示从1.5V到1000V的所有电压量程。选择需要的量程。选择量程的原则时，选择最接近被测电压最大值并且大于被测电压最大值的电压量程。这样可以保证量程误差尽量小。如果不知道被测电压大小，或者被测电压波动比较大，可以打开自动量程，WT5000会根据被测电压的实际大小调整量程。
我们按照同样的方式进行电流量程的设置。5A输入单元的电流量程从5mA到5A，选择合适的固定量程，或者选择自动量程。
如果所用的电流传感器是电压输出型的，则需要将这个外部传感器开关打开。再选择合适的二次侧电压量程。然后设置好传感器的变比。
30A输入单元的电流量程是从500mA到30A。设置方法与5A输入单元相同。
电流传感器输入单元的电流量程是从10mA到1A。设置方法也与5A输入单元类似。
设置量程的另一种方法是通过实体按键进行设置。
这种设置方式更加直观且便捷。
这里有7个按键，分别对应主机后面的7个输入单元。例如我们想调节第1个单元的量程，我们点亮按键1，然后通过下面的调节按键选择合适的电压量程或者电流量程。点亮Auto按键，将会开启自动量程。同理，我们可以设置其他输入单元的量程。
对于量程来说，还有一些其他的相关设定，需要点开<输入（高级）Input (Advanced/Options)>设置。
并择<量程>(Range)菜单。
第一项是<峰值因数>(Crest Factor)选项。默认值是CF3。如果被测信号的波动很大，需要频繁切换量程时，可以尝试选择CF6或者CF6A，一般来说可以有效减少因为信号波动产生的量程切换。
第二项是电流量程的显示格式。默认是<变比前量程>(Direct)，量程显示为直接输入电流的量程。另一个选项是<变比后量程>(Measure)，选择它后，电流量程显示为使用电流传感器可以测量的电流范围。
第三项是<量程关联>(Range Link)设置。默认是ON状态，此时同一个接线系统只需要设定一相的量程，同一组里的其他相都会自动设为相同的量程。如果设为OFF，则需要为接线系统中的每一相分别设置量程。
在<量程配置>(Range Config)菜单下，我们可以看到所有输入单元的量程配置情况。在自动量程时，量程是按照这里的量程顺序进行切换的。有些情况下，为了能减少量程切换时间，可以把不关注的量程关闭。
点击<有效测量量程>(Valid Measurement Range)按键，进入到这个界面。在这里把不需要的量程前面的对钩取消掉，就可以在量程切换时直接跳过这些量程，从而实现量程快速切换。
以上是关于WT5000量程设置的操作方法。设置合适的量程以及相关参数，可以获得更加精准的测量结果，并且能够使测试过程更加平顺。
对于只需将数据保存下来的用户而言，使用WT5000高精度功率分析仪标配的网络服务器（Web Server）功能就可轻松实现如同现场一样的设备操作

CAN Bus communication is widely used in the transportation industry where reliable transmission of data is paramount. Monitoring and recording these communications can be easier when using the proper instruments. In this video, a Yokogawa Test&Measurement Applications Engineer demonstrates how to setup the DL950 ScopeCorder to read the temperature of a motor drive alongside its voltage and current output.
This video demonstrates how to test to an IEC standard (IEC 61000) using a Yokogawa Test&Measurement WT5000 Precision Power Analyzer and the harmonic flicker testing software. The software automates the process of judging if the device under test is compliant with the chosen standard and allows you to output the necessary test reports for your records.
This video demonstrates how to measure transient phenomena on power signals using the Yokogawa Test&Measurement PX8000 Precision Power Scope.
In several applications, especially those testing AC power to a standard such as IEC61000-3-11, the voltage and current signals must be monitored to confirm there are no major dips and/or swells in the signal. This can be done with instruments capable of reporting rms values, including power analyzers, traditional oscilloscopes, and some data acquisition systems.
To test to a standard, however, the instrument must have an accuracy spec that is traceable back to a national standard of calibration such as ISO17025 or NIST.
