The Measurement Challenge
Various measurements at tests points on the motor and drive system require specialized equipment optimized to ensure the highest quality with few trade-offs. The correct instrument may depend on the level of accuracy, number of channels, or type of signal being acquired.
This application note details the process for measuring and verifying proper motor function using a power analyzer, and how to troubleshoot common errors in the measured output.
Measurement guidance related to field-oriented control (FOC) of electric motors with example use cases that illustrates how this is accomplished using a power analyzer and/or a ScopeCorder. Specifically addressed are direct and quadrature currents of a surface-mounted permanent magnet motor (SMPM) with field weakening applied. The techniques illustrated can also be applied to other FOC variables, algorithms, and motor technologies.
To best utilize SiC devices for improved energy efficiency in equipment, it is important to optimize the internal device peripheral circuits in the inverter according to the device characteristics.

With the increased demand in electric-hybrid vehicles, the electromechanical designs of in-vehicle systems are becoming more sophisticated and there has been a demand shift towards high efficiency brushless direct current motor (BLDC) implementation. Think of motorized seat adjustment, electric window, power steering, HVAC fans, pumps, etc. In many of these systems various types of motors are used as actuators; more specifically, 3-phase BLDC motors are gaining popularity as they provide these important advantages:
- Improved speed vs torque characteristics
- High dynamic response
- High efficiency
- Extended speed ranges
- Long operation life
How can I capture data from motion sensors synchronized with other analog data? The Yokogawa ScopeCorder series of instruments feature input modules and functions to make this possible.

It’s not an exaggeration to say I owe a good bit of my career success to Yokogawa Test&Measurement. By using their ScopeCorders that combine the best parts of an oscilloscope and DAQ, projects that once took weeks across multiple instruments suddenly only took a few hours with just one instrument. The impact on what I could accomplish really was quite remarkable, and my ability to accurately complete projects in record time made me look incredible. No matter how complex or convoluted the task, the ScopeCorders never fail to easily handle anything I throw at them. They’re amazing instruments and I tell others about them every chance I get. —Kenneth Shoemaker, Automotive Industry Consultant/Owner at Panama Prototypes
We developed an algorithm to optimize induction motor operation and produce an average power consumption savings of at least 10%. To demonstrate our algorithm’s effectiveness, we needed a proven and verified system that would give these results credibility. The solution provided by Yokogawa Test&Measurement enabled us to monitor and refine our algorithm using real-time speed, power, and temperature readings – data that would normally be incredibly difficult to accurately obtain. Having these real-world results that demonstrate the effectiveness of our algorithm means we can be more efficient with our own customers. —Neil Singer, President, AC Kinetics

Key topics include:
While DC power measurements are relatively straight forward, AC power measurements that include distorted waveforms, varying power factors, and multiple phases can add complexity to an otherwise simple measurement. During this webinar, we cover multiple fundamentals of power measurement.
Key topics include:
Why should you be concerned with your product’s power system voltage and current harmonics? From an engineering perspective, harmonics produce excessive heat in equipment that causes significant damage and results in inefficient operation. From a business perspective, compliance is an absolute requirement for entry into global markets. To minimize or eliminate these issues and establish acceptable levels of harmonics, numerous power quality standards with specifications and limits for harmonic distortion, such as IEEE 519-2014 and IEC61000-3-2, have been introduced. During this webinar, attendees will gain knowledge on the inner workings of harmonics, learn best practices for accurately measuring harmonics, learn to recognize and distinguish the critical difference between DFT and FFT, and discover important measurement tradeoffs across various test equipment.
