There are many ways to measure current waveforms. Give two practical examples. The condition is that you have an oscilloscope with a frequency converter that measures the output current of the motor. First, a Hall current sensor is used to connect any one of the three phases of the motor into the sensor. On the output side of the sensor, the waveform of the low voltage is measured with an oscilloscope, and then calculated according to the primary/side ratio of the sensor. The measured current size; Second, the monitoring parameter of the actual value of the output current of the inverter is output through the analog output terminal of the inverter, and the oscilloscope is connected to the terminal to directly detect the waveform. 0-10V or 0-20mA corresponds to the full value of the current. You can convert it yourself. Of course, if you have a Fluke voltage and current oscilloscope. Not to mention, direct detection. Very convenient.
