You've got a electric motor in for repair and the repair shop indicates that your problem lies in the windings. Maybe when you are reviewing the quote you see the acronym VPI in connection with the rewinding process.
Before you sign off on the repair, you want to know what is involved with VPI or Vacuum Pressure Impregnation, and whether its a smart choice for your motor. If that's you, you've found the right place.
Why Motor Winding Insulation is Important
Insulation of motor windings / coils serves three key purposes:
- Insulate the windings from potential contaminants (electrical and physical)
- Dissipate heat generated by the windings
- Make the windings rigid and secure
These are all vital for efficient operation of your electric motor.
