Product Detail

YB-300 CNC Rectangular Coil Winding Machine for Voltage Transformers (Patented)

Achieve precision and automation in rectangular transformer coil production with the YB-300. Engineered to overcome the challenges of manual winding (high labor intensity, inaccurate turns), this patented CNC machine delivers a revolutionary breakthrough for square/core winding. Its intelligent PLC system automates wire length calculation, storage, counting, and stop-memory. The 360° rotatable iron core enables seamless winding around chamfers and round corners. With a max speed of 100rpm and 1.5KW power, it significantly boosts product performance and production efficiency for VT/PT manufacturers.
