Slot Wedges

Good magnetic conductivity

High electrical and thermal resistance

GFK

Product

Slot wedges are made of magnetic or non-magnetic material and are used as slot locks to hold the stator windings in the slots formed between the stator teeth. Slot wedges made of magnetic material are an important means of improving the efficiency of a motor or generator.

Properties

Slot wedges are pressed components made from a prepreg material, these have good magnetic conductivity and high electrical and thermal resistance combined with excellent mechanical strength.

Application

Magnetic slot wedges are used, for example, as slot locks for induction motors, in the automotive industry, wind generators and traction motors.

Magnetic slot wedges are used in the entire field of LV and HV generators, especially in the automotive industry, renewable energies, shipping.
