A 4-Step Process for Testing Motor & Drives Systems
White Paper

Electric motors are electromechanical machines that convert electric energy into mechanical energy. Despite differences in size and type, all electric motors work in much the same way: an electric current flowing through a wire coil in a magnetic field creates a force that rotates the coil, thus creating torque. Understanding power generation, power loss, and the different types of power measured can be intimidating. This white paper gives an overview of basic electric and mechanical power measurements and the interfacing of drives in motors.

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.

 


Overview:

In this application note you will learn when and how to use different methods to connect a current transformer to a power analyzer.

Overview:

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
Overview:

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. 

Overview:

Use built-in calculations to analyze motor rotor position of Brushless DC motors (BLDC) and Permanent Magnet Synchronous Machines (PMSM) and find the relative angle between the rotor and position sensors such as encoders or resolvers 

Application Note
Overview:
  • How to Measure Harmonics with WT3000E Harmonic Measurement Meter
  • Harmonics standards compliance
  • Measuring up to 50 orders of harmonics at 1 KHz
  • 4 input elements
  • Measuring phase angles between phases

Product Overviews

    Overview:

    The current sensor element for the Yokogawa Test&Measurement WT5000 Precision Power Analyzer is ideal for applications requiring a current transformer for high-current measurements. The internal DC power supply simplifies preparations before measurement, requiring only a connecting cable and eliminating the external power supply.

    The WT5000, an industry-leading power analyzer, features seven field-removeable elements, 10 MS/s, 1 MHz power bandwidth, 18-bit resolution, and 0.03% basic power accuracy. Yokogawa Test&Measurement continues to innovate on the platform, enabling /D7 data streaming, /G7 harmonics, and flicker analysis.

    The new current sensor element replaces the traditional current inputs and includes a sensor input terminal with integrated ±15V power supply, eliminating the need for an external power supply. The isolated voltage terminals remain the same as the 5A and 30A elements.

    Overview:

    Test and measurement engineering work groups can have differing priorities and requirements, which often results in multiple instrumentation systems and data file formats, as well as incompatible reporting. This lack of effective communication between groups and instruments causes decreased efficiency and quality and increased spending and time to market. Unify test and measurement instrumentation, software, and data across engineering teams with a suite of solutions that caters to the different needs of engineering work groups, including accurate power data, fast sampling rates, long recordings of multiple different input types, and insights into waveform data.

How-tos

    Overview:

    Having multiple memory options allows engineering groups to optimize how data is stored, no matter if you need to record for a long time at slower sampling rates, do a fast capture at high sampling rates, or anything in between.

    The Yokogawa Test&Measurement DL950 ScopeCorder operates as an oscilloscope and incorporates the ability to record data for long periods of time like a data acquisition recorder. There are four memory types on the DL950 ScopeCorder: internal memory, solid state drive, flash memory, and PC storage through the IS8000 Integrated Test and Measurement Software Platform. This videos talks about the advantages of each of these and how to pick the best data recording method for you.

Webinars

    Overview:

    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:

    • Multi-phase measurements
    • Measurement techniques
    • Measurement applications
    • Real-world examples and more
