Information
Product Overview
Designed for the highly efficient mass production of precision toroidal coils and current transformers, the SIPU Fully Automatic Toroidal Winding Machine series offers both Slider-Type (for fine wire precision) and Belt-Type (for versatile applications) configurations.
Built with a compact footprint and high mechanical rigidity, these machines ensure extremely stable continuous operation. The advanced tension control and vibration-free feeding system make it the ideal turnkey solution for manufacturers looking to upgrade from manual or semi-automatic winding to fully automated, labor-saving production.
Key Features & Advantages
Ultimate Labor Saving: Highly automated design allows a single operator to supervise 10 to 50 machines simultaneously, significantly reducing operational costs.
10-Minute Quick Changeover: Features a simple and rational translational structure for core picking and placing. Product specification changeovers and fixture replacements can be completed within just 10 minutes.
Zero-Defect Turn Counting: Equipped with a Dual Optical Fiber Monitoring System. If any discrepancy in turn counting is detected, the machine triggers an automatic alarm and shuts down to prevent defective yields.
Vibration-Free Core Feeding: The rotary table feeding system operates silently without vibration, ensuring the fragile magnetic properties of the cores are never compromised during arrangement.
High Versatility: The belt-type model supports both differential-mode and common-mode winding on a single machine, easily switchable via the intuitive touch screen.
Applications & End Products
This machine is the backbone equipment for the power measurement, electrical protection, and telecommunication industries, specifically handling fine wires down to 0.07mm without breaking.
Power Measurement & Smart Grids: Miniature Current Transformers (CT), Voltage Transformers (PT). Widely used in Smart Electricity Meters, smart grid monitoring devices, and energy management systems.
Electrical Safety & Protection: Residual current coils and trip coils used in RCCB / ELCB / RCBO (Earth Leakage Circuit Breakers) and industrial safety switches.
Audio & Telecom Power: EMI filter chokes and toroidal power transformers used in high-end Audio Amplifiers, telecommunication base stations, and sensitive medical equipment.

FAQ
Q1: What is the main difference between the Slider-type and Belt-type toroidal winding machines? A: The Slider-type is specifically designed for very fine wires (0.07mm - 0.30mm) and smaller cores, offering maximum precision for miniature current transformers and delicate sensors. The Belt-type is more versatile, handling slightly thicker wires (0.10mm - 0.80mm) and a wider range of core sizes, making it ideal for both common-mode and differential-mode coils.
Q2: How difficult is it to change product specifications (changeover) for different coils? A: It is incredibly fast and user-friendly. Thanks to our optimized translational structure for core picking and placing, an operator can complete a full specification changeover—including fixture replacement and HMI recipe adjustment—within just 10 minutes.
Q3: How does the machine ensure the exact number of turns without wire breakage? A: Precision is our priority. The machine is equipped with a high-accuracy Dual Optical Fiber Monitoring System. It counts every single turn perfectly. If any discrepancy or wire issue occurs, the machine triggers an automatic alarm and shuts down immediately, ensuring zero defective yields.
Q4: How many machines can one operator manage? A: Because the machine features fully automatic core feeding, threading, and winding, manual intervention is minimized. A single operator can easily supervise 10 to 50 machines simultaneously, drastically cutting your factory's labor costs.
Q5: We are located overseas. Do you provide installation support and spare parts? A: Yes, absolutely. SIPU is a global supplier. We provide comprehensive technical support, including detailed English manuals, step-by-step video tutorials, and online video troubleshooting. Standard spare parts (like shuttles and optical fibers) are always in stock for fast global delivery to keep your production running smoothly.
