I consider one of the greatest challenges to be analyzing the fundamental oscillation of the voltage for motors with PWM supply. Development will have to pay more attention in the future to correct synchronization of all electrical and mechanical quantities as well as certification of results such as efficiency and torque.
New technologies have to be developed in the area of power electronic components and new materials have to be developed for constructing electric motors. The integration of power electronics and the electric motor is also crucial. Assuming sufficient information is available for the motor and inverter, their efficiency can be improved by optimizing the control strategy.
We have benefited from powerful data acquisition and storage. Some very useful post-processing functions are available for analyzing data. There is one great advantage here compared to the conventional power meter / oscilloscope combination: Many more non-electrical quantities can be recorded, such as torque, rotational speed and temperature. And time offsets can now be compensated for. They are a thing of the past in data acquisition.
In this article, we explain how to have efficient testing of electrical machines and electrical inverters from a user perspective. We dive into options, such as power supplies and inverters, to help engineers while typically trying to maximize efficiency across a drive cycle.
It‘s very important for us to correlate electrical, mechanical and thermal quantities to have a complete image of the drive machine.
We haven‘t used the live power calculation yet, but it could provide useful information for online testing.
We expect there will be wireless data acquisition from the sensor to the data recorder. Sample rates and sensor bandwidths implemented by 2020 should at least double. Measurement technology of the future will also offer us fast data processing in real time and options for EMC testing.
