Slot Wedges

Magnetic and non Magnetic Slot Wedges

Slot Wedges made of either magnetic or nonmagnetic Material used as Slot Closures to hold the stator windings in the slots formed between the stator teeth.

Slot wedges made of magnetic material are a significant means to improve the efficiency of a motor or generator. Magnetic slot wedges reduce slot ripple in the air gap flux caused by the changing reluctance due to the slots, and also reduce the associated eddy current losses due to the interaction of the harmonics in the air gap flux with the conducting surface of the rotor.

The magnetizing current required in the stator windings to generate the desired air gap flux is less with magnetic slot wedges, since more of the air gap flux is available for useful power production.

Further, our magnetic Slot wedges are not produced from Sheets which means a massive Improvement since cutting and grinding of Sheets with High Glass Content has a Major Impact on Health.

Slotwedge Flexibility Demonstration

This extremely high flexibility is a result of SPI's patented Production Process. If you try this with any Competitors Wedge, it will most likely break or delaminate.
