Why we updated HyMPulse
HyMPulse has been the reference pulsed-field hysteresisgraph since 2005 — in continuous use in R&D labs, production QC environments, and the quality departments of magnet manufacturers. Over twenty years of field data and several hundred installations tell us what customers actually push the system to do, and where it becomes the bottleneck rather than the enabler.
Three themes drove the 2025 redesign: the operating temperature envelope isn’t wide enough for modern automotive and aerospace specifications; the cycle time between pulses needs to come down as production volumes rise; and real-time derived parameters (B_r, H_cJ, H_cB, knee point, BH_max) should be available immediately, not after an offline analysis step.
What’s new
Extended temperature envelope: −40 °C to +220 °C
Previous generations operated reliably from 0 °C to +180 °C. The 2025 release extends both ends: −40 °C for automotive cold-start validation and Arctic/aerospace applications, and +220 °C for high-temperature rare-earth characterization and thermal demagnetization studies. The temperature controller uses a redesigned sample chamber with improved thermal isolation and faster stabilization.
Redesigned capacitor stage
The high-voltage capacitor bank has been rebuilt with modern film capacitors, reducing physical footprint by 18% while cutting pulse recovery time from ~45 seconds to under 20 seconds between full-field pulses. The delivered pulse shape is unchanged — this is a performance and maintainability improvement, not a measurement behavior change. Existing measurement results remain directly comparable to the previous generation.
Integrated real-time analysis
The HyMPulse software now computes all standard derived parameters as the measurement completes, rather than requiring a separate analysis pass. Operators see B_r, H_cJ, H_cB, knee point (H_k) and BH_max within a few seconds of the pulse, with full measurement traceability preserved for offline review. This makes the system viable as a production tool in environments where cycle time matters, not just as an R&D instrument.
Safety and compliance
The system now ships with updated CE marking to the latest Machinery Directive revision, improved door interlocks, and new emergency-stop routing that reduces the post-stop recovery sequence from minutes to seconds.
Backwards compatibility
Customers with earlier HyMPulse installations can upgrade the software stack (real-time analysis, updated UI, expanded export formats) in the field. The extended temperature envelope and redesigned capacitor stage require hardware retrofit — we offer a return-to-factory upgrade program with a typical 4-week turnaround. Contact us for a retrofit quote for your serial number.
Availability and lead time
New HyMPulse 2025 systems are in production now, with typical lead times of 14–18 weeks from purchase order depending on configuration. Demonstrations are available at our Leuven headquarters and at major trade events — we showed the new system at PCIM Europe in June and will run full demonstrations at CWIEME Berlin 2026.
