Overview:

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.

Overview:

Using the OR trigger and Dual Capture, it is easy to trap and record failure conditions on electrical harnessses (wiring interconnects) over a long duration test.

Product Overviews

How-tos

    Overview:

    In this video we demonstrate the GPS data logging capability of the DL350 Portable ScopeCorder. Recording Position, Velocity, and Altitude simultaneously with accelerometers or other analog inputs is simple with the DL350's built-in features.

    Overview:

    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.

    Overview:

    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.

    Overview:

    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.

Webinars

    Overview:

    With ongoing innovations in motor and inverter technologies seeking to advance global decarbonization objectives in the automotive industry, it’s crucial that engineers have a thorough understanding of how to properly analyze these systems.

    This complimentary webinar provides engineering professionals involved in motor and control system development with insights that enable data benchmarking and troubleshooting issues related to energy efficiency in electric vehicle (EV) powertrains.
