MRI Coil Winding System
(For Large Diameter Coils)

Coil Winding System
MRI – Magnetic Resonance Imaging

CoilWinder MRI Winding Machines provide for a wide range of coil sizes, coil styles and wire types, for smaller extremity diagnostic units to larger MRI units with former diameters over 2 meters diameter.


  1. Constant precision wire tensioning with dancer/accumulator.
  2. Automatic wire dereeler alignment with guide arm.
  3. Single speed range and multi-speed winders.
  4. Heavy-duty welded steel construction for superior strength.
  5. AC Vector drives for precise speed control.
  6. Servo wire guide traverse: Two precision layering styles are provided; Parallel and Spiral.
  7. Control station custom configured to your application.
  8. Quick-select touch screen wire tension control.
  9. Linear wire usage readout.
  10. Live wire tension display.

Headstock Connection: Steel faceplate or 3-jaw self-centering chuck.

Primary Reduction: Timing belt and pulleys.

Secondary Reduction: Gear reducer or multi-speed gearbox, depending upon model.

Spindle Rotation: Either direction can be selected by a switch on the control panel.

Spindle Center Height: 43" (1092 mm) from the floor or as required to accommodate coil diameter swing.

Brake: Brake on the main drive motor and also after the gear reduction on the output shaft, operated by removing foot from variable speed control, by total turns count programming or by emergency stop button.

Tailstock: Mounted on precision ways to allow positioning anywhere along winding axis. Large crank handle provides easy movement. Locking hardware to hold tailstock firmly in position.

Tailstock Connection: May be 3-jaw self-centering chuck, steel faceplate, saddle bearing with locking yoke or as required.

Maximum Distance Between Centers: As required.

Maximum Swing Diameter: As required.

Machine Control: MP-4 Microprocessor controller – Custom control systems may also be provided as required.
