Core Kinematics: Needle Winding Engineering for High-Pole BLDC Stators
In modern industrial electric drive fabrication, the migration from brushed DC armatures to brushless DC (BLDC) and permanent magnet synchronous motors (PMSM) requires an evolution in coil placement mechanics. Conventional external flyer winders rely on rotating arms spinning around an armature core; conversely, internal-slot brushless stators necessitate precision CNC multi-axis needle winders.
Nakro’s automated brushless stator winding equipment implements synchronized multi-axis servo articulation (X, Y, Z axes complemented by precise θ-axis rotational indexing). The wire-guiding needle enters directly into the stator bore, oscillating through narrow slot openings down to 1.2 mm clearance. By sustaining consistent closed-loop tension via magnetic or electronic brake transducers, our equipment suppresses micro-abrasions in the insulation enamel and optimizes the copper slot-fill factor up to 45%–52% in concentrated winding configurations.

Localized Industrial Application Scenarios in Western Lithuania
As the primary industrial port city of Lithuania and an epicenter of Western Baltic advanced engineering, Klaipėda presents distinctive operational environments demanding high-durability electric motor manufacturing.
Maritime & Port Electrification
Klaipėda’s active seaport ecosystem (including ship repair, port cargo-handling equipment, and automated terminal logistics) demands brushless thrusters, marine auxiliary pump drives, and saltwater-resistant winches. Nakro’s BLDC winding machines build stators capable of taking heavy epoxy varnishing without slot displacement.
Offshore & Coastal Wind Auxiliaries
Lithuania's rapid expansion in Baltic wind energy infrastructure calls for high-reliability permanent magnet generators and brushless pitch/yaw servomotors. Our precision stator production lines configure multipole windings with symmetric electromagnetic balance, mitigating harmonic vibration under erratic wind conditions.
Klaipėda FEZ & Baltic Clean-Tech
Enterprises operating inside the Klaipėda Free Economic Zone (FEZ) developing electric municipal vehicles, parcel delivery e-scooters, and modular HVAC systems rely on high-volume outer-rotor wheel hub lines and BLDC stators providing high torque density and zero-defect quality traceability.
Key Trends Reshaping Drive Production in Lithuania
Understanding macroeconomic and technical shifts allows regional engineering directors to design future-proof production facilities.
Stringent EU EcoDesign Directive Compliance
Lithuanian builders are prioritizing IE4 (Super Premium) and IE5 (Ultra Premium) efficiency standards. Achieving these ratings hinges on precise winding slot fill, uniform tensioning that eliminates wire stretching, and exact phase resistance symmetry across all motor poles.
Industry 4.0 MES/SCADA Port Integration
Klaipėda-based manufacturers increasingly mandate that stator production stations integrate directly into factory-wide MES systems. Nakro machines incorporate standard OPC-UA, Ethernet/IP, and Modbus TCP protocols for continuous logging of turns, tension curves, and surge test data.
Nearshoring & Flexible Automation
To reduce supply-chain latency across the EU single market, Baltic enterprises are reshoring winding processes previously outsourced elsewhere. High-speed retooling, quick changeover collets, and self-diagnostic CNC modules provide the operational agility needed for local just-in-time schedules.
From Slot Insulation to Final Hi-Pot Verification
A rigorous five-stage manufacturing flow guaranteeing motor reliability before shipping to Klaipėda and international assembly lines.
01. Insulation Insertion
Automatic shaping, cut-off, and press-fitting of slot cell paper (DMD, Nomex, or Mylar) or specialized plastic end-cap insulators into bare lamination stacks with zero edge distortion.
02. CNC Needle Winding
Multi-axis needle travel guided by servo algorithms ensuring accurate layer placement, constant active line tension, programmable lead-wire routing, and automated terminal hook wrapping.
03. Terminal Termination
Micro-resistance welding, hot-crimping, or ultrasonic bonding of copper magnet wire ends to brass terminals, PCB pads, or lead wires without manual scraping of enamel insulation.
04. Integrated Stator Test
100% automated electrical end-of-line testing covering DC winding resistance, AC Hi-Pot (dielectric breakdown), surge impulse comparison, and phase-to-phase insulation resistance.
