1. This machine is widely used for high-voltage stator coil expansion. It automatically shapes the coil from its initial shape to a rectangular cross-section shape through the movement of the thruster and the cylinder clamp. It is used for one-time forming of shuttle shaped coils, large shuttle shaped coils, and ship shaped coils. This machine is used for pulling the stator frame shaped coils of large and medium sized motors with longer expansion prisms or larger cross-section motors.
