**AC Drive System: The Revolutionary Technology of 21st Century Electric Forklifts**
By Yang Xiaojun, Beijing Jiaotong University
The forklift, often referred to as the "God of Handling," plays a crucial role in logistics and material handling. In recent years, China's forklift market has experienced remarkable growth, with an average annual sales increase of over 30%, far outpacing the national economic growth rate. As one of the most active markets globally, China has attracted significant attention from international players.
Although internal combustion forklifts still dominate the domestic market, the growing awareness of environmental protection has led to increased demand for cleaner, more reliable electric forklifts. The AC drive system, which uses an AC motor as its core, is hailed by industry experts as a revolutionary technology of the 21st century due to its high efficiency, low maintenance costs, and superior performance. Leading global forklift manufacturers are continuously launching new AC-driven models to meet user needs and gain a competitive edge. Chinese companies are also investing heavily in R&D to develop advanced AC systems, positioning themselves to compete both domestically and internationally.
**First, the demand for electric forklifts is on the rise, with foreign enterprises holding a large share of the market.**
Electric forklifts use batteries as their power source, offering zero emissions, low noise, and easy operation. These advantages have driven a steady increase in their market share, especially in ports, warehouses, and industries like tobacco, food, and textiles. The charts below illustrate the growth in electric forklift sales in Japan and Europe, showing a clear shift toward cleaner alternatives.

China's forklift industry has developed into a mature sector, with key players such as Anhui Forklift Group, Hangzhou Forklift, and Dalian Forklift leading the way. In 2004, these companies sold over 34,689 internal combustion forklifts, while electric forklifts accounted for 12,783 units. Despite this growth, the market is still dominated by foreign companies, particularly in high-end segments.
**Second, the advantages of AC drive systems are becoming increasingly evident.**
With advancements in semiconductor technology and frequency conversion, AC motors now offer higher efficiency, smaller size, and longer life compared to DC motors. They eliminate the need for carbon brushes and commutators, reducing maintenance costs and improving reliability. Additionally, regenerative braking systems allow energy recovery during braking, extending battery life and lowering operating costs.
AC drives also improve productivity, enabling faster acceleration and smoother operation. This results in higher efficiency and better performance, making them a preferred choice for modern forklifts.
**Third, the AC drive system supplier landscape is evolving.**
Danaher Motion is a leading provider of AC drive solutions, offering integrated systems that ensure optimal performance and reliability. Their technology is used by major global forklift manufacturers, including Toyota, Jungheinrich, and Komatsu. Danaher Motion continues to innovate, developing high-performance permanent magnet AC motors that promise even greater efficiency and compactness.
**Fourth, the application of AC drive systems is expanding globally.**
Foreign markets have already embraced AC-driven forklifts, with many top manufacturers adopting the technology. In China, the adoption of AC systems is still in its early stages, but several major companies are beginning to integrate these systems into their products. With increasing demand and technological improvements, the future of electric forklifts looks promising.
In conclusion, the AC drive system represents a major leap forward in electric forklift technology. As it becomes more widespread, it will significantly impact the industry, driving innovation, enhancing competitiveness, and shaping the future of material handling. Those who embrace this technology will be well-positioned to succeed in the evolving global market.
