THE MOTOR DRIVE ANALYZER – A NEW CLASS OF INSTRUMENT Instrument Evolution The increasing speed, size, and complexity of three-phase power electronics and drives systems calls for new instrument paradigms that can acquire any drive or motor signal and perform any debug, validation or analysis on the complete drive system, including three-phase power and efficiency calculations. That new instrument is the Teledyne LeCroy Motor Drive Analyzer. It has capabilities that previously required multiple instruments. The Motor Drive Analyzer has the bandwidth (1 GHz at 2.5 GS/s), inputs (8 analog channels...

Motor Drive Analyzer Complete Capability Power analyzers perform a single function, and have their place as a “golden-reference” power measurement device. But they are limited to steady-state analysis and provide simple “black-box” analysis. 4 channel and/or 8-bit oscilloscopes are good for basic embedded control debug and validation, but they lack enough inputs for complex drive system and control loop analysis, and don’t have enough resolution to precisely measure power and efficiency values. The Motor Drive Analyzer has none of these limitations, can acquire any analog, digital, serial data,...

MORE CAPABILITY THAN YOU EVER IMAGINED WAS POSSIBLE The Motor Drive Analyzer provides an extensive range of capabilities to allow you to debug your three-phase power electronics or motor drive design faster than ever before. Don't limit yourself to one screen - attach a UHD (4k) monitor and create a larger palette to perform your analysis on. Take a single long acguisition of a dynamic event, and with the press of one button, zoom through the waveforms and gate the measurement results to the zoomed area. Change the zoom position and the measurement tables and per-cycle "synthesized" Waveforms...

5. Vertical Zooming Capture then vertically zoom for detail, as shown here in the DC bus voltage and current signals 6. Q-Scape Displays Use Q-Scape multi-tabbed displays to organize waveforms onto separate tabs, then view them all at once, or one tab at a time 7. Statistics Table Displays the complete measurement set statistical data for any Numerics table 8. Per-cycle “Synthesized” Waveforms Enhances and speeds understanding of complex behaviors. Note the red trace (Torque) clearly shows torque ripple behaviors. 9. Multi-Stage Power Analysis with Efficiency Calculated stage-stage and overall...

BEYOND “NUMBERS” - MORE INFORMATION Numerics Measurement Table Like a power analyzer, a user-configurable table is provided for display of a selection of power (real, apparent, reactive), power factor, phase angle, efficiency, voltage, current or motor mechanical parameters. Up to 120 values total may be displayed in 10 rows and 12 columns for any selection of input or output individual phase or total three-phase, DC bus/link, or motor mechanical values. Efficiency, slip, and rotor angle may also be displayed. The numeric values displayed are mean values from a statistical data set that is calculated...

MORE DEBUG AND VALIDATION FLEXIBILITY Dynamic Drive Response The long acquisition memory in the Motor Drive Analyzers (up to 250 Mpts/Ch) provides unique capabilities for motor and drive dynamic response analysis. For example, 25 seconds of continuous acquisition capture is possible at a sample rate of 10 MS/s. This permits complete un- derstanding of dynamic drive behaviors, such as startup, application of load, or fast changing load conditions, and correlation of drive response problems to control system instructions or power section failures. This 480V drive has 70 second acquisitions for...
