Insertion Winding

Insertion Winding

Heavy Duty Insertion Winding Machines

The ZET and SCW winding machines are high-speed, stator coil winders for two- and four-pole induction motor winding. The machines are capable of winding multiple wires in hand with special features for wire grippers and dereeler depending on wire size. Combining winding and coil/wedge insertion is an option in many machine configurations. Coil insertion and winding is driven by an AC servo motor and ball screws for a smooth operation.


  • Reliable Construction
  • Efficient & Precise
  • Superior After-Sales Service

Typical Ranges

Stator ID: 110 – 150mm
Stator OD: 175 – 230mm
Wire In Hands: 10 – 20, (depending on # of layers on winding former, # of turns, and wire diameter)
Lead Length 300 – 600mm
Main Axis Number of Rotation Stock Winding – 400 rpm Winding – 300 – 600 rpm
Wire Dia 0.5 – 1.2mm

These are typical product sizes. The capability of the machines to manufacture each stator depends on a number of factors including end turn dimensions, winding pattern, bus bar design, etc. Please contact an Odawara sales representative with your unique requirements.
