Broomfield 900 Series

Extra large capacity, very high torque coil winding machine.

The Broomfield 900 coil winder is a single speed, machine that can handle large, heavy coils and can provide very high winding torque. Our most powerful single speed winder, it can be manufactured with various speeds and torques according to your application requirements.

Three models available:
900A: Winding headstock
900B: Winding headstock with tailstock mounted on precision ways.
900C: Winder headstock, tailstock on precision ways and automatic wire guide traversing mechanism.
  • Single speed range with variable speed
  • Heavy-duty welded steel construction
  • Air actuated disc brake for positive stopping
  • Electronic wire guide traverse: Two precision layering styles are provided; Parallel and Spiral (900C).
  • Setup time is minimized by the use of electronic controls for precisely setting wire pitch and stopping at the desired turns count (900C). The operator only needs to enter this data and set the winding width stops.
  • Reverse bend system eliminates the need for pounding wire or pressing coils into shape, produces tighter coils and uses less wire (900C).
  • Easily adaptable for winding single or multiple coils.
