Engineered to exact DIN EN 60034 electro-technical tolerances and high slot-fill coefficients. Designed for continuous 3-shift duty cycles across Central European industrial workshops.
The Plzeň Region (Plzeňský kraj) stands as one of Central Europe's most influential engineering cradles, combining century-old transportation machinery heritage with Tier-1 automotive and electromobility manufacturing hubs.
Within the Pilsen-Borská Pole industrial zone and the adjacent D5 motorway logistical artery connecting Prague to Bavaria, Tier-1 suppliers produce high-volume 12V/24V starter motors, windscreen wiper drives, cooling fans, and electric power steering (EPS) armatures. Our multi-spindle automatic armature winders (such as the ZB-302 and ZB-303 series) provide high tension repeatability, reducing wire scrap and ensuring tight balance tolerances across high-RPM automotive rotors.
Rooted in Plzeň's world-renowned legacy of rail vehicles, suburban electric trains, and trolleybus propulsion, regional electrical engineering groups require high-torque traction motors capable of enduring extreme thermal cycling and shock loads. Our flat copper shaping and wave-coil winding units (CJL-7 and 4-BL-1) deliver precision geometry for heavy stator slots and high-power armatures, matching the stringent requirements of urban transit fleets.
The manufacturing cluster surrounding Nýřany, Rokycany, and Stříbro accommodates extensive production lines for industrial hydraulic pumps, refrigeration compressors, and ventilation equipment. These systems demand IE3 and IE4 Super Premium Efficiency induction and permanent magnet synchronous motors (PMSM). Our horizontal stator inserting (DQ-1, DQ-2) and wedge paper machines (DFC-1) ensure slot-fill factors above 78% without enamel scraping.

Analyzing the technological upgrades shaping machine procurement in the Western Bohemian manufacturing basin over the next decade.
Conventional round enameled wire is rapidly being substituted by rectangular flat copper (hairpin winding) in EV drivetrains and high-output alternators. Rectangular conductors increase thermal conductivity, lower resistance losses, and offer higher copper space utilization. Rilvo's 5-SC-2B and CJL-7 machines automate multi-stage bending and end-forming with negligible copper work-hardening.
Czech plants require real-time MES and ERP data integration. Our winding cells incorporate industrial Ethernet (Profinet, EtherCAT) and OPC-UA connectivity. Production managers can track winding tension curves, hook fusing temperatures, and cycle times in real time, fulfilling ISO/TS audit trail mandates.
With stringent European Union ecodesign directives (Regulation EU 2019/1781), electric motor manufacturers face strict efficiency baselines. Meeting IE4/IE5 performance limits requires precise stator coil slot-packing, tight end-turn dimensions, and low residual mechanical stresses—all guaranteed through Rilvo's servo-guided insertion tooling.
As plant operations shift toward agile, small-batch flexibility, changeover downtime between rotor models must be minimized. Our machines feature quick-release modular winding heads, RFID-recognized tooling plates, and touch-screen recipe storage that reduce job setup times from 3 hours to under 20 minutes.
Founded in 1998, Zhejiang Rilvo Automation Equipment Co., Ltd. has established itself as an innovative high-tech enterprise dedicated to automated motor manufacturing lines, armature winding solutions, commutator micro-spot welding machines, and advanced electrostatic powder coating systems.
Occupying a modern 60,000-square-meter campus in the Shatianyang Development Zone of Sanmen, Taizhou (Zhejiang Province), Rilvo houses more than 150 precision machining centers, CNC milling units, and dedicated inspection laboratories. Our manufacturing base includes 20,000 square meters of operational workshops with an additional 30,000 square meters constructed for advanced e-mobility production line integration.
Under the leadership of our President and Chief Engineer—honored as a national knowledge-worker model by the All-China Federation of Trade Unions—our 36-member specialized R&D engineering division retains 17 national utility and invention patents. We operate under full ISO9001:2015 quality management procedures and hold China Compulsory Certification (3C).
