Coolant Ingression Problems. Some spindle Motors have coolant that runs thru them, when seals fail this can cause the stator to short out, like in the one seen in the above left image. If the Motor is damaged or burnt out we have the ability to rewind it and encapsulate it to prevent this sort of damage from happen again, an example of an encapsulated winding is shown in the above right image. Coolant ingression can also damage bearings by washing out lubricant and causing them to overheat due to excessive friction. It is standard for us to replace bearings for all repairs, it is something our spindle technicians are very skilled at.
