Product Description
Product name: Wooden Slot Wedge (slot closure key)
Description:
The wooden slot wedge, also known as a slot closure key, is a precisely machined component with a semicircular cross-section, designed for use in the slots of stators and rotors of electric motors and other rotating electrical machines.
Its primary function is to provide mechanical fixation of enamelled wires and securely close the slot, preventing displacement during operation due to vibration and centrifugal forces.

Usage Note:
The slot wedge must match the exact dimensions of the motor slot. The semicircular wooden wedge can be easily cut to size by hand. After installation, it is recommended to apply an insulating varnish.
For motors with a higher thermal insulation class, fiberglass-reinforced, polyester resin-based composite slot wedges may be more suitable – also available in our product range.
