900 Series Coil Winding Machines

Extra large-capacity, very high-torque coil winding machine.

The Broomfield 900 is a high-torque, single-speed coil winder designed for large, heavy coils. As our most powerful single-speed model, it can be customized with various speed and torque options to meet your specific application needs.

Three models are available:

900A: Winding headstock.

900B: Winding headstock with tailstock mounted on precision ways.

900C: Winding 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.
