HV Motor Coil Spreading Machine

CNC Motor Coil Spreading & Forming Machine

Inquiry Form

We provide HV motor coil spreading machine for spreading & forming spindle-shaped coils from coil winding machine into exact shapes that are easy to insert into the stator slots of big size motors.

Main features
  • Large scope of application for different terminal shape, straight section length and coil section area
  • High forming precision, no need further re-ordering, applicable for both mass production and new prototype production
  • Full digital control, simply inputting parameters on HMI, intuitionistic and convenient
  • High precision, servo motor controls coil length, terminal height, arc angle and spreading gap
  • Easy to use, hydraulic clamping and arc pushing
  • Parameters can be saved and recalled for next time use
