Stator Winding Needles

Motor Winding Needles (Stator / Rotor)
High-performance needles for in-slot stator and rotor winding applications
Eurotubes UK is a global leader in the design and manufacture of in-slot motor winding needles — also referred to as stator winding guides, rotor wire guides, winding tubes, or simply winding needles. These precision components are essential in automated stator winding machines, where enamelled copper wire is inserted, wrapped, and layered around stator poles with speed and accuracy.

Working alongside OEM machine manufacturers and end users, we develop custom winding needles optimised for:

  • Longevity under high-speed, multi-axis motion
  • Dimensional consistency for repeatable machine performance
  • Surface finish quality to eliminate insulation damage and wire breaks
  • Precision tolerances in compact, space-restricted stator designs

 

Over 25 Years of Specialisation in Stator Winding Needles
Since 1999, Eurotubes UK has specialised in the rapid prototyping, design, and production of stator and rotor winding needles. Today, we operate from a state-of-the-art facility using CAD-CAM-CNC machining, proprietary techniques, and advanced polishing systems to deliver world-class components trusted by electric motor manufacturers worldwide.
We support both low-volume, small batch manufacturing and high-volume production, with lead times as fast as 7-10 working days for new needle designs. For returning customers, we aim to hold stock for same-day dispatch.

 

Typical Applications

  • In-slot winding of stators and rotors for electric motors on automated / robotic winding equipment, within assembly production cells, and on standalone machines
  • External or Internal Needle Winding Platforms requiring ultra-fine tolerances
  • Multi-head, high-speed coil winding machines
  • Compact stator assemblies with narrow slot openings or angled geometry

 

Material & Design Capabilities

  • Specially hardened tool steels & advanced powder metallurgy alloys
  • Optional DLC (Diamond-Like Carbon) coating, achieving over 2500HV+ surface hardness for outstanding wear resistance and reduced friction
  • Fully customised geometries including angled exits, wire deflectors, and anti-jam profiles
  • Internal bores as fine as 0.20mm
  • Tapered, oval, or elliptical shaped bores to suit specialised wire handling or dynamic winding conditions
  • Mirror-finished internal radii forms and polished bores for safe and consistent wire passage

 

Pricing & Lead Times
Winding needle pricing depends on the design complexity, features, and finishing requirements. As a general guide, batches of 6 pieces typically range from £150–£350 per needle.
