Celebrating Hertz Innovation (HzI):
Dynamic Contactless Power Supply Cumulative Delivery Exceeds 100 km!
Hertz Innovation (HzI) | Milestone Announcement
Jointly developed with leading AMHS partners, HzI’s Dynamic Contactless Power Supply System has delivered over 4 years of uninterrupted, high-reliability power to OHT systems in dozens of front-end and advanced packaging projects—serving 10+ semiconductor fabs, packaging plants, and LCD panel manufacturers across Mainland China, Taiwan, and Southeast Asia.
Cumulative Deliveries Exceed 100 km of OHT Track Since 2022!
A momentous achievement reflecting our sustained focus on wireless power innovation for cleanroom AMHS.
As semiconductor manufacturing processes advance, production steps continue to multiply rapidly, driving up throughput demands on critical machinery. Traditional manual handling can no longer satisfy the requirements of high-efficiency production. Automated Material Handling Systems (AMHS)—including Overhead Hoist Transports (OHT) and Stockers for transferring and storing wafer FOUPs—significantly boost production efficiency and yield rates through fully automated transport.
As wafer fab scales expand and OHT track networks extend, cleanroom power systems face higher demands for continuity, stability, and contamination control.
Conventional contact power supplies are ill-suited for cleanroom AMHS due to mechanical wear, friction particles, and maintenance issues. Dynamic wireless non-contact power supply enables on-the-go energy transfer without physical contact, serving as the essential backbone for modern OHT systems.
Based on electromagnetic induction and magnetic coupled resonance, Wireless Non-Contact Power Supply (CPS / HID / DWPT) overcomes legacy bottlenecks:
Zero Contamination & Superior Reliability: Eliminates physical wear and sparks; prevents metallic particle contamination to protect sub-14nm process yields.
High Dynamics & High Efficiency: Delivers stable power to OHTs running at high speeds of up to 5 m/s across multi-track, fab-wide layouts.
Lifecycle Cost Savings: Wear-free design dramatically cuts long-term maintenance costs.
Historically, Japanese players like Muratec and Daifuku dominated the semiconductor AMHS market, primarily because domestic non-contact power supply systems were missing as a core supporting technology.
Around 2020, numerous domestic AMHS suppliers entered the market. Initially, several companies suffered setbacks by applying German contactless power supply systems—intended for non-semiconductor industrial manufacturing—to OHT applications. A small number of manufacturers adopted South Korean contactless power supply products, which came with high price tags and sluggish customer service responsiveness.
Drawing on its deep technical expertise and continuous innovation in Wireless Power Transfer (WPT), Hertz Innovation (HzI) has remained committed to in-house R&D, continuously investing in dynamic wireless contactless power supply technologies and products for OHT applications. Tailored to the stringent demands of semiconductor cleanrooms and benchmarked against Japanese industry leader Daifuku, HzI has driven continuous technological breakthroughs, rapid product iterations, and rigorous engineering validations.
In 2022, HzI launched a competitive, domestically developed dynamic wireless contactless power supply solution for OHT systems, matching international standards. This milestone filled a critical technical gap in China, empowered domestic AMHS development, and broke key bottlenecks to achieve supply chain independence and control in semiconductor material handling equipment.
High-Availability CPS: Achieves redundant takeover in $<100\text{ ms}$ upon power anomaly detection.
Zero Single-Point Failure: Prevents line stoppage and ensures continuous, 24/7 OHT vehicle operation over long distances.
Cleanroom-Friendly WPT: Sub-10kHz low resonant frequency with low-radiation inverter technology drastically lowers EMI/EMC impact on surrounding sensitive machinery.
Multi-Kilometer Synchronization: High-precision phase synchronization via hybrid CAN/fiber-optic networks keeps multiple power units synchronized across multi-kilometer OHT track layouts.
Co-Transmission (Signal Modulation): Utilizes inverter current modulation for real-time emergency stops, OHT traffic control, and track energy management.
Core Energy-Saving Patent Granted: Secured a landmark patent—likely the world's first focused on energy-saving mechanisms for contactless power tracks.
System Evolution: Evolving from simple power delivery to a smart, integrated architecture combining power, communication, system synergy, and energy efficiency.
