An increasing number of manufacturers are using magnetic wedges in their form-wound machines. When a winder fails to replace magnetic wedges in kind, the winding temperature rise can increase by 20°C, and the magnetizing current can increase by 20% or more.

  • Why some manufacturers use magnetic wedges 
  • Benefits of magnetic wedges
  • Downside of magnetic wedges
