Overband magnet for the waste industry

CovElec are sometimes called on to repair all manner of equipment. Here an overband magnet used in the waste management sector weighing approximately 5 tonnes had failed electrically. The magnet coils had developed a short circuit and burnt the coils and cabling. 

The conductor on the 3 coils was formed from electrical grade aluminium strip with the 3 coils stacked on top of each other. The coils were wet wound with a lacquer applied while the strip is tensioned when wound around a central former.

They are further bonded to the core and housing using a silicone rubber moulding solution to ensure the vibration couldn't develop further faults when put back in service
