of an original, or master, coil is reduced into
multiple narrower coils. A wide range of
materials and thicknesses can be slit, ranging
from thin foils to thick plate.

Early detection and correction of problems
prevent expensive repairs.

• DC motors require more maintenance than their AC
  counterparts
• In DC motors energy consumption is more
• Expertise in DC drives is not easily available
• A shift to AC can reduce maintenance costs by
  nearly 20
• Slot bar marking and burning might take place if
  DC motor is not working efficiently
• Dark streaks along the brush path might be found
• Threading might sometimes transfer excessive
  amounts of metal to brushes
• Grooving is another common pattern where
  commutator material is worn away this can lead
  to flashover and arcing
