As electric powertrain engineering accelerates toward higher DC bus voltages (800V architectures in electric vehicles and high-efficiency IE4/IE5 industrial motors), the stator core serves as the most critical electromagnetic and thermal junction. A stator testing machine is no longer merely a pass/fail continuity checker; it has evolved into a multi-parameter diagnostic hub. Quality verification must confirm turn-to-turn insulation health, inter-phase dielectric capability, magnet wire tension stability, and ground wall insulation integrity before the vacuum pressure impregnation (VPI) or trickle varnishing stage.
Standard high-potential (Hi-Pot) AC/DC testing can confirm macroscopic dielectric clearance between phase windings and the laminated iron core stack. However, early-stage latent defects—such as microscopic enameled wire micro-scratches caused by high-speed needle winding nozzles or coil insertion pusher blades—remain invisible to low-voltage resistance measurements. Our integrated test stations employ non-destructive, high-frequency impulse surge generators (up to 5000V) coupled with high-speed digital sampling oscilloscopes. By evaluating the Area Difference Ratio, Corona Discharge Ratio, and Flutter Value of the reflected resonant LC waveform, the system detects insulation breakdown long before a dead short develops in the field.
Utilizes ultra-fast rise-time voltage pulses to stress inter-turn magnet wire coatings. Waveform area and differential oscillation analysis identify micro-shorted winding turns without damaging intact enamel insulation.

Aligning test equipment compliance with the industrial requirements of the Lesser Poland Innovation Hub, the Kraków Technology Park (KPT), and regional Tier-1 automotive assemblies.
The Małopolska voivodeship, anchored by Kraków, has transitioned into one of Central Europe's most prominent electro-mechanical engineering clusters. Supported by the academic precision of the AGH University of Krakow and the Cracow University of Technology, global automotive Tier-1 suppliers, industrial automation leaders, and clean mobility startups have established extensive production bases within the Kraków Technology Park Special Economic Zone, Niepołomice Investment Zone, and Skawina industrial sectors. The implementation of high-throughput stator testing machines plays a pivotal role in ensuring that regional assembly lines comply with European automotive standards (IATF 16949) and international electrotechnical mandates (IEC 60034-18-41).
Kraków’s expanding green mobility sector manufactures direct-drive wheel hub motors and mid-drive motors for electric cargo bikes, e-scooters, and urban municipal utility vehicles. Our testing systems execute fully automated no-load Back-EMF, Hall sensor angle offset, and phase sequence checks directly on finished outer-rotor hub stators.
As Central Europe accelerates heat pump and high-efficiency HVAC production, regional facilities require stator testing hardware capable of evaluating high slot-fill, concentrated winding BLDC motors. Testing protocols measure insulation performance under high-moisture and refrigerative dielectric stresses.
Serving the broader industrial corridor connecting Kraków, Katowice, and Rzeszów, motor manufacturing facilities produce three-phase induction and synchronous reluctance drives. Our machines deliver simultaneous inter-turn surge, high-voltage withstand, and phase balance analytics on IE3, IE4, and IE5 rated stators.
How Industry 4.0 integration, hairpin stator architectures, and strict EU ecodesign directives are redefining quality assurance benchmarks.
Modern production facilities across Kraków require zero data isolation. Our stator test benches embed native OPC UA protocols, allowing full parameter uploading (surge decay curves, resistance variance, leakage values) directly to factory ERP/MES architectures for individual unit traceability.
Automotive traction drives are transitioning from conventional round-wire pull-in winding to flat-wire rectangular hairpin stators. Hairpin architectures involve hundreds of laser-welded copper joints, requiring precision micro-resistance scanning and partial discharge inception voltage (PDIV) checks.
With the European Union tightening industrial motor efficiency metrics under eco-design mandates, manufacturing margins are razor-thin. Measuring accurate iron loss anomalies and micro-short turns during dry stator stages prevents assembling defective cores into finished motors.
