Where does EV motor efficiency really get lost? ⚡🏎️

As EV motors push higher speeds and greater performance, engineers need more than standard measurements—they need visibility into exactly where losses occur.

PWM-driven motors create complex harmonics and low power factor conditions that can make accurate measurement extremely challenging.

With the Hioki PW8001 Power Analyzer, engineers can:
✔ Capture high-accuracy measurements from DC to 5 MHz
✔ Reduce phase shift errors with automatic phase correction
✔ Analyze copper and iron losses in real time using User Defined Functions (UDF)
The result? More accurate efficiency mapping and smarter design decisions for next-generation EV motors.

⚡ Advanced waveform monitoring is critical for accurate three-phase UPS operation testing.

To properly validate UPS performance in industrial and critical power environments, engineers must simultaneously monitor multiple electrical and thermal parameters during normal operation, switching events, and power interruptions.

Typical measurements include:
• Three-phase input voltage and current
• Three-phase output voltage and current
• Energy storage device voltage and current
• Temperature and additional system signals

Capturing these signals at high speed allows engineers to identify:
✔ Power transition delays
✔ Voltage/current anomalies
✔ Switching instability
✔ Harmonic disturbances and spikes

The Hioki MR8848 Memory HiCorder supports this application with high-speed sampling and synchronized multi-channel acquisition, enabling comprehensive visualization of UPS system behavior on a unified waveform display.

How do you detect a motor failure before it happens? ⚡🌡️

As EVs evolve, motors are enduring more extreme loads and higher temperatures than ever. Standard checks aren't enough—to ensure true reliability, you need to see the "why" behind the heat.

The secret lies in synchronization.

By linking the Hioki PW8001 Power Analyzer to the LR8450 Data Logger via CAN communication, engineers can finally correlate electrical stress with temperature fluctuations in real time.

Why this matters for your R&D:
Capture Instantaneous Drops: See exactly how a performance dip correlates with a thermal spike.
Noise-Resistant Data: Maintain accuracy even in high-noise SiC inverter environments.
Scalable Testing: Monitor up to 120 thermal channels alongside high-precision power metrics.

Don’t leave your durability assessments to chance. Empower your testing with a quantitative edge.

⚡ Ensuring reliable UPS performance requires more than standard measurements — it requires capturing transient behavior during real operating conditions.

When testing single-phase UPS systems, engineers must simultaneously monitor:
• Input and output voltage/current
• Battery voltage and current
• Temperature behavior
• Transition timing during outages and recovery

These measurements help identify:
✔ Transition delays
✔ Instability during switching
✔ Harmonic distortion
✔ Noise originating from the power grid

High-speed waveform acquisition is essential to accurately capture these fast transient events.
The Hioki MR8848 Memory HiCorder supports this application with high-speed multi-channel recording capabilities, enabling engineers to overlay voltage, current, and temperature waveforms for deeper UPS system analysis and validation.
