Motor and inverter test

Motor dq analysis functionMotor dq analysis function (/MT1 option)

The /MT1 option calculates Park and Clarke transformations in the DL950 from battery DC voltage/current, three-phase motor voltage/ current, and motor rotation information.
It can be combined with motor parameters, power measurement, and harmonic analysis.
A single DL950 can also integrate other measurements such as vibration, temperature, and CAN monitoring.

DL950 ScopeCorder Power and Harmonics Analysis | Yokogawa Test&MeasurementPower and harmonics analysis (/G05 option)

A single DL950 is all you need to evaluate a system with battery-driven motors, such as an EV. The DL950 calculates the conversion efficiency from the input and output power of the inverter and analyzes the effects of harmonics caused by external disturbances while capturing mechanical variations in motor speed and torque.

DL950 ScopeCorder Encoder Rotary Angle | Yokogawa Test&MeasurementEncoder rotary angle (/G03 or /G05 option)

The DL950 can calculate the rotation angle from the pulses output from an encoder and display the trend of the rotation angle as a waveform. The rotation angle and its control signal can be simultaneously observed and inspected for abnormalities.

Long term data recording

DL950 ScopeCorder Dual Capture Function | Yokogawa Test&MeasurementDual capture function

For durability testing, it is necessary to capture transient phenomena with a high-speed sample rate, even when monitoring low-speed data to visualize long-term trends. The dual capture function uniquely resolves these conflicting requirements by simultaneously recording at two different sample rates.

Physical phenomena analysis

DL950 ScopeCorder Strain Gauge Transducer Measurement | Yokogawa Test&MeasurementStrain gauge transducer measurement (/G03 or /G05 option)

Load, pressure, and acceleration can be measured by connecting a strain gauge-type transducer such as a load cell or torque sensor. This feature automatically calculates conversions from cumbersome calibration values and enables easy setting.

Power line analysis

DL950 ScopeCorder Power Line Abnormality Detection | Yokogawa Test&MeasurementPower line abnormality detection (Wave Window Trigger)

Special triggers are used to detect frequency fluctuations, voltage drops, and other phenomena that are difficult to detect with ordinary triggers. These triggers can also be used to detect typical power supply problems such as momentary power loss, sags, and surges.

8 G points large memory (/M2 option)

With up to 8 G points of memory and 20 seconds of continuous capturing, even at 200 MS/s, no signal changes are missed. *Up to 4 G points of memory is allocated per channel.

8 G points large memory (/M2 option)

SSD recording (/ST1 or /ST2 option)

The 512 GB internal SSD can record for long periods of time at up to 2 MS/s. Waveforms from dual capture can also be recorded, which is useful for in-vehicle endurance testing and capturing rare spontaneous events.

SSD recording (/ST1 or /ST2 option)

Flash acquisition (/ST2 option)

Long time recording at up to 20 MS/s, which is 100 times faster than the previous model, is available. You can capture data anywhere you cannot bring a PC such as on-vehicle or field testing. The flash memory is non-volatile, so the captured data stays in the instrument even after turning off the power. Data can later be transfered to a PC.

Flash acquisition (/ST2 option)

Deletion of the recorded data on the flash memory is not done for each recorded data but for all the data at once.
When transferring recorded data to a PC, please use the IS8000 or re-save the data in WDF format.

Multi-sample rates

Sample rates can be set by channel. Reducing the sample rate reduces the amount of data even when modules with high and low sample rates are mixed together. This allows for less memory space to be used and improves the transfer speed.

Summary of each recording mode

Real-time mathematical computation (/G03 or /G05 option)

Various calculations are performed on captured signals and the results are displayed on the screen in real time. Perform triggers, automatic waveform parameter measurements, and cursor measurements. Independent input channels, real-time calculation results of 32 input channels plus 16 real time math channels can be displayed and analyzed simultaneously.

History function

Any abnormalities occurring during repeated waveform measurement will have disappeared by the time they are noticed. Since the DL950 stores up to 5000 waveforms (history waveforms) in the acquisition memory, it is possible to go back and display the abnormal waveforms. Search for and easily find waveforms from the stored history waveforms and display only those that match specified conditions. Search conditions such as amplitude, frequency, or a zone that a waveform passes through or does not pass through can be specified.

Action on trigger and GO/NO-GO judgement

This performs multiple actions specified in advance when a trigger occurs, such as saving data file, buzzer and email transmission. Also, pass or fail (GO/NO-GO) determination can be performed based on waveform parameters, such as waveform shape or amplitude, and an action can be executed according to the determination results.

High noise resistance

The DL950 is designed to be resistant to noise and can measure waveforms correctly even when installed close to an inverter. If the touch panel malfunctions, simply turn off the touch panel and use the keys and jog dial to operate it.

Other functions

  • Recorder mode (set the record time and sample interval)
  • Up to eight power supplies for current probes (/P8 option)
  • Operation with a USB mouse, keyboard, and external printer

Example Applications

2-motor/4-motor system test for EV

In the development of Hybrid Electric Vehicles (HEVs), a 2-motor or 4-motor system in which a motor is directly connected to each driving wheel is applied. This eliminates powertrains, which enhances the design and removes anxiety when driving a 4WD on a snowy road. The multi-channel/high-speed isolated DL950 can capture signals and analyze them at the same time in the multiple motor systems.

High noise immunity

The DL950 measures the DC power on the battery side and the AC power on the 3-phase motor side at the same time. It simultaneously measures all inverters, including the power generation motor, and evaluates the conversion efficiency. With its high noise immunity, the DL950 minimizes the effect of switching noise generated by the inverters. CAN, CAN FD, LIN, and SENT signals from the ECU and the temperature rise in each part can be captured at the same time. Data can be saved in a MATLAB format as well. When an isolated module is used, there is isolation between the body and channels and isolation between channels, so that different points of common potential can be safely measured.

High noise immunity

Distributed energy resource test (renewable energy)

The DL950 supports renewable energy sources which contribute to a sustainable society. For wind turbines, the efficiency of power generation at multiple locations needs to be monitored in a time-synchronized manner. This can be done by GPS and IRIG. In addition, the DC/AC conversion efficiency for loading the DC power onto the grid can be accurately measured by the WT5000 high-precision power analyzer via IS8000. The power values and their trends can be analyzed.

Vibration analysis solution

All moving things are bound to have vibration. The DL950’s acceleration module allows for simultaneous capture of multiple vibration frequencies. Use the FFT function to analyze the frequencies and find abnormalities.

In-vehicle data measurement solution

The DL950/VCE option provides enhanced features and functions mainly for vehicle development and evaluation. Supporting 720245 CAN FD/LIN Monitor Module and 720243 SENT Monitor Module, the DL950 can display each protocol communication data of in-vehicle networks as trend waveforms on the monitor. It can also trigger on decoded waveforms.

Comparative verification between measured signals and CAN/CAN FD bus signals

The CAN/CAN FD bus data and related waveforms can be viewed on the same screen. For example, an ignition switch ON/OFF signal, a CAN FD signal corresponding to that command, and pressure signals can be checked on the same screen to verify the correlation between them.

Location and time information inclusion

By connecting an accessory GPS unit, information such as location (latitude, longitude, altitude, and so on) and time can be included in measurement data. Correlation between the location of a vehicle and power data, CAN data, or other types of data can be viewed during a vehicle drive test.

Utilization of vehicle-installed network definition files

The Symbol Editor is a software tool that makes it possible to define which physical values from the CAN/CAN FD or LIN bus data frame have to be trended as waveform data on the display of the ScopeCorder. The Symbol Editor can accept vehicle-installed network definition files (CAN DBC, LIN LDF).
