How to Measure Motor Mechanical Speed, Torque and Power Webinar

3-Phase Power and Motors Masters Webinar Series
Join Teledyne LeCroy for this Learning Lab series on measuring high-power, three-phase and motor inverter and drive systems with an 8-channel high-resolution oscilloscope or motor drive analyzer. Learn about static and dynamic measurements, from AC line to inverter switching, and line outputs to motor mechanical performance.

How to Measure Motor Mechanical Speed, Torque and Power
In this session (Part Six), we focus on how to use the Motor Drive Analyzer to measure motor mechanical shaft speed, torque and angle using a variety of analog, digital and serial data sensors.

Topics to be included:

  • Resolvers and Sin/Cos sensors
  • Quadrature Encoder Interface (QEI)
  • Brushless DC (BLDC) Hall sensors
  • Extracting speed data from CAN serial data
  • Inference/calculation of speed or torque from other acquired data

Register for the rest of the series:

Part One: How to Measure Inverter Dead Times and Input/Output Power
Part Two: How to Perform Static and Dynamic Power Analysis
Part Three: How to Correlate Control Events to Power Events
Part Four: How to Measure Power During Volt-second and Other Short Power Periods
Part Five: How to Perform AC Input and Inverter/Drive Output Harmonic Analysis

Who should attend? Inverter subsection engineers, motor/drive control system engineers, and inverter/drive systems engineers who design dynamic control and power systems that operate under highly controlled conditions.

What attendees will learn? Best in class techniques for measuring and understanding performance of and interrelationships between control and power sections.

Presenter: Stephen Murphy, Teledyne LeCroy Applications Engineer

Pre-work recommended before attending the Learning Lab webinar

It is recommended that you download and register (at no cost) MAUI Studio prior to the start of the Learning Lab, and download LabNotebook (waveform plus setup files) .lnb files (they will be combined into one .zip file that will need extracting).

MAUI Studio
>> https://teledynelecroy.com/mauistudio/

Zip file with .lnb files
>> File will be available before webinar starts

These files will allow you to load the various waveform examples shown during the Learning Lab webinar, and participate in hands-on instruction.

Setting up Your Timebase and Using Memory Correctly Webinar

Join Teledyne LeCroy for this 30-minute Oscilloscope Coffee Break Series to remind us how to get the most test and debug capability from our oscilloscopes. Grab your refreshment and spend a few minutes with us as we focus on a specific topic each month.

We are all pretty good at setting a time window for our capture. But, what about the waveform memory that is used for the capture? How does this interact with the sample rate as we vary the time window? Can we segment the timebase to capture only the important circuit behaviors?

Topics to be included:

  • Timebase, memory length and sampling rate – how do these impact our results?
  • Timebase delay – pre- and post-trigger location
  • Sequential timebase – capturing “just the facts”
  • Scope preferences we forget are available

Optimizing Your Vertical Gain Webinar

Join Teledyne LeCroy for this 30-minute Oscilloscope Coffee Break Series to remind us how to get the most test and debug capability from our oscilloscopes. Grab your refreshment and spend a few minutes with us as we focus on a specific topic each month.

Why do we care about vertical dynamic range? How do we take the most advantage of this to achieve the highest accuracy and precision? In this session we review your oscilloscope’s vertical gain and why we should care about it.

Topics to be included:

  • Vertical dynamic range – why do we care?
  • Effects on measurement accuracy
  • DC versus AC coupling – pros and cons
  • Should we overdrive the scope?
  • Vertical offset versus scope sensitivity

Testing Noisy Power Supply Outputs

Join Teledyne LeCroy for this 30-minute Oscilloscope Coffee Break Series to remind us how to get the most test and debug capability from our oscilloscopes. Grab your refreshment and spend a few minutes with us as we focus on a specific topic each month.

We didn’t expect to have DC outputs be so noisy! Is it really the circuit that is a problem or is our scope and/or probe causing signal integrity issues? We even tried changing output capacitors to improve the performance, but why are we seeing 2X greater output noise than we expected?

In this session we review which probes are best for your application and how best to connect to your oscilloscope to minimize RF pick up.

Topics to be included:

  • Scope setups, which is best?
    • 1 MΩ or 50Ω?
    • AC or DC Coupling?
    • Bandwidth limits?
  • Probing output power
    • What is the appropriate probe to use?
    • Challenges with DC-DC low impedance sources
    • Accessories – how do we reduce probe effects on our measurements?
