Motor and inverter test

Motor 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.

Power 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.

Encoder 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

Dual 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

Strain 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

Power 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.

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.

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)
