How Is a Stator Made? Inside the Automated Stator Manufacturing Process A finished stator looks simple: a laminated steel core, copper windings, insulation, and connection points. In reality, that compact component is the result of a tightly controlled manufacturing sequence. A shifted piece of slot paper can lead to insulation failure. A poorly formed coil can make insertion unstable. A small scratch on enamel wire can become a failed electrical test. This is why the stator manufacturing process is not just about putting copper into steel. It is about controlling insulation, geometry, electrical connection, and repeatability from the first operation to final testing. Below is a practical walkthrough of how a stator is made in an automated stator production line. 1. Insulation Paper Insertion: Creating the Slot Insulation Barrier The process usually begins with insulation paper insertion. Insulation paper is placed into the stator slots to separate the copper winding from the lam...
