Automatic Stator Coil Inserting, Expanding & Forming Machine

The Automatic Stator Coil Inserting, Expanding & Forming Machine is an integrated automation solution that combines stator coil inserting, coil expanding, and forming processes into a single machine. It is specifically designed for medium and large stators that require multiple coil insertion operations, helping manufacturers improve production efficiency while ensuring consistent product quality.

The machine is widely used in the production of pump motors, submersible pump motors, deep-well pump motors, and other medium and large induction motors. Through an automated multi-cycle inserting and expanding process, it provides reliable stator processing performance while supporting a wide range of stator specifications.

With its highly integrated design and flexible manufacturing capability, the machine reduces manual intervention, minimizes process transfer time, and serves as an efficient solution for automated motor production lines.

• Integrated Coil Inserting, Expanding, and Forming Process

  The machine combines stator coil inserting, coil expanding, and forming operations into one automated system, reducing production steps while improving manufacturing efficiency and product consistency.

• Automatic Slot Wedge Feeding and Inserting System

  The machine automatically performs fixed-length slot wedge feeding, cutting, forming, and synchronized insertion together with the stator coils, ensuring efficient and reliable insulation processing.

• Automatic Multi-Cycle Expanding and Forming Process

  After each coil insertion cycle, the stator is automatically transferred to the expanding station for precise coil expansion and forming. The process is repeated automatically until the complete insertion sequence is finished.
