Broomfield 500 Series

Large capacity coil winding machine.

The Broomfield 500 Series is a three speed coil winding machine that is often used for winding larger diameter coils at lower speeds. In its headstock only configuration, the 500A is a very rugged and economical choice for hand winding.

Three models available:
500A: Winding headstock
500B: Winding headstock with tailstock mounted on precision ways.
500C: Winding headstock, tailstock on precision ways, and automatic wire traversing mechanism.
  • Three speed ranges with variable speed within each range (Maximum speed 85 RPM).
  • Heavy-duty welded steel construction
  • Electrically actuated brake for positive stopping
  • Electronic wire guide traverse. Two precision layering styles are provided, parallel and spiral (500C).
  • Set-up time is minimized by the use of electronic controls for precisely setting wire pitch and stopping at the desired turns count (500C). The operator only needs to enter this data and set the winding width stops.
  • Reverse bend system eliminates need for pounding wire or pressing coils into shape, producing tighter coils and using less wire (500C).
  • Easily adaptable for winding single or multiple coils.

Motor Equipment: 2 HP (1.49 kW) AC vector motor and drive with foot controlled variable speed.

Faceplate: 14" (356 mm) diameter

Primary Reduction: Belt and pulley

Secondary Reduction: Gear reducer
