End-to-End Stator Manufacturing Capabilities

Sotek is not a repair-only shop. We are a full-scale U.S. manufacturer capable of managing the complete stator assembly lifecycle. Our teams work directly with OEM engineers and maintenance leaders to reduce lead times, control quality, and maintain strict compliance with original design requirements.

Lamination Stacking & Core Pressing

Magnetic performance starts with steel quality and stack integrity. Sotek handles lamination forming, precision stacking, and high-force core pressing to ensure structural stability and magnetic efficiency under continuous-duty conditions.

Coil Winding & VPI Processing

We provide precision coil winding and Vacuum Pressure Impregnation (VPI) to protect stator windings from vibration, thermal stress, moisture, and electrical breakdown in demanding industrial environments.

Final Assembly & Electrical Testing

From rewedging and core restacking to final rotor insertion, every stator assembly undergoes controlled build steps and electrical testing to verify performance before shipment.

Solving Complex Stator Production Challenges Nationwide

Whether supporting a national locomotive remanufacturing program or a new OEM motor platform, Sotek has the capacity, experience, and process control to deliver consistent results across large-scale projects.
