High-strength slot closing wedges
Excellent electrical insulation properties
High-strength and high-precision
High-performance closing wedges
In electric motors, copper windings are fixed into the stators by papery or foil-like dividing layers and electrically screened. In high-performance motors, where higher demands are placed upon the mechanics, these materials are not sufficient. A high-precision solution is needed to guarantee optimum performance.
Our high-performance thermoplastic slot closing wedges, with excellent electrical insulation properties, provide high-temperature resistance to screen off the windings of electric motors reliably and permanently. By using plastics with iron-based fillers, it's also possible to enhance the magnetic permeability of the material. This increases the efficiency of both motors and (particularly) generators. Our high-precision extrusion method ensures smooth surfaces and exact contours to suit your every need.
