US Patent 8729748 Split stator and manufacturing method thereof

Disclosed are a split stator and a manufacturing method thereof with which insulation reliability can be improved by preventing deformation or cracking of the insulator by eliminating slippage of the insulator at the coil end face. A slip prevention mechanism that prevents slippage of the insulator is provided at the coil end face, and using insert molding, the insulator is integrally molded to a split stator core provided with the slip prevention mechanism.
