Custom Lamination Cores

Windtech Inc. makes stator cores to precise Customer specifications. You can provide the laminations or let us procure them for you. We can make them straight or skewed; with or without end insulators. We also have the capability to perform several machining operations such as: OD grind, ID honing, chamfer, notches, thru holes, and several others. Windtech can design and fabricate the complete tooling required for bonding, machining, end lamination placement and all other required steps. We can also work with Customer-supplied tooling.
