Visão Geral:

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.

Visão Geral:

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-tos

    Visão Geral:

    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

    Visão Geral:

    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.

    Key webinar topics include:

    • Establishing baselines for system efficiency
    • Conducting inverter control signal analysis at the systems level
    • Identifying critical measurements for benchmarking inverter input, inverter output, and motor output
    • Analyzing motor control signals, including torque control variables, positional sensors, and pulse-width modulation (PWM), as well as torque measurements
    Visão Geral:

    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
