This webinar will explain the DC redesign process along with the other factors often overlooked that should first be considered before a redesign.  As DC machines become difficult to source it’s not uncommon for an end user to ask about re-designing a DC motor that they have in storage, including changes in voltage for the shunt field and armature circuit.  Topics include:

  • Shunt fields
  • Reconnection for voltage change
  • Change limitations
  • Series fields
    • Cautions about circuit change
  • Armature circuit voltage change
    • Interpoles
    • Brushes, boxes and current density
    • Armature redesign considerations

This webinar is intended for winders, shop supervisors and engineering staff.
