Foil Coil Winding Machine



BRJ series foil coil winding machine is for winding foil type coils in transformer and electric apparatus.
Foil coils use copper or aluminum foils of different thickness as conductors, and broad strap type insulation materials as interlaminar insulation; narrow strip type insulation materials as terminal insulation. They are winded to be roll type coils. Also, the inside and outside down-leads will be welded and the outer surface will be wrapped. So, each function of the equipment can provide sufficient support to the manufacturing of foil coils which comply with the specification requirements. The machine is the necessary equipment for producing the components of this kind of electrical products.


1.   The equipment actuating mechanism adopts the pneumatic component control other   than the motor, avoiding the phenomenon of hydraulic oil leakage;
2.   The welding system adopts the imported linear guide rail and ball screw;
3.   It adopts the photoelectric servo motor to control the planes of the coil face with fast response;
4.   The electrical appliances of the machine are controlled by PLC with frequency control.
5.   Tension adjustment can be made on the control panel on demand
