DC fan coil motors are the mainstream type of motor used in fan coil units, and the current market size is steadily expanding driven by energy-efficiency policies and the growth of the air-conditioning market. Looking ahead, clear development directions can be identified across multiple dimensions, including technology and applications. The following is a detailed analysis based on industry reports:
Market Size
Motors for DC fan coil units are predominantly brushless DC motors (BLDC) and permanent-magnet synchronous DC motors (PMSM). The market size for these motors has grown steadily, driven by the overall growth of the fan coil unit motor market, with specific data as follows:
Overall Market Size: The total market for fan coil unit motors in China is projected to reach RMB 15 billion in 2025, representing a year-on-year growth of 11.1%. Among these, DC motors remain the clear market leader, with the share of brushless DC motors expected to rise to 70% and that of permanent-magnet synchronous DC motors to 30%. Based on these projections, the market for DC motors used in fan coil units is estimated at approximately RMB 13.5 billion in 2025, making it the core driver of the fan coil unit motor market.
Regional distribution characteristics: the Yangtze River Delta, the Pearl River Delta, and the Beijing–Tianjin–Hebei region are the core consumption hubs. In 2025, the market size for such motors in the Yangtze River Delta is projected to reach RMB 5.2 billion, up 12.5% year on year; in the Pearl River Delta, it is expected to be RMB 4.8 billion, up 10.8%; and in the Beijing–Tianjin–Hebei region, RMB 3.5 billion, up 9.2%. These three major regions boast robust economies, high air-conditioner penetration, and a strong receptiveness to energy-saving technologies, making them the primary drivers of demand for DC fan-coil unit motors.
Application Scale: Central air-conditioning systems represent the largest application segment, accounting for 67% of the overall fan coil unit motor market, with a market size of approximately RMB 9 billion in 2025. In addition, the DC fan coil unit motor markets for split-type and portable air conditioners are projected to reach RMB 3.5 billion and RMB 1.5 billion, respectively. Demand from emerging applications such as fresh-air ventilation systems and air purifiers is also growing, with an expected market size of RMB 1 billion in 2025.
Development Trends
Continuous deepening of technological iteration
Implementation of New Materials and Processes: The adoption of rare-earth permanent-magnet materials and 0.2-mm ultra-thin silicon steel sheets will further reduce iron losses in electric motors and enhance energy efficiency; meanwhile, processes such as laser welding and automated winding will improve the stator lamination factor and winding yield, thereby reducing operational losses. In addition, the use of third-generation semiconductor materials—such as SiC—in motor controllers will further boost the overall efficiency of motor systems.
Enhanced Intelligent Capabilities: Motors will be extensively equipped with IoT modules and embedded sensors, enabling remote monitoring of speed and operating status, as well as AI-driven predictive maintenance to proactively detect issues such as bearing wear and abnormal winding temperature rise. In addition, integration with Building Management Systems (BMS) will be further strengthened, supporting communication protocols like Modbus for centralized control and management.
Steady expansion of market demand
Policy-driven adoption of high-efficiency products: National “dual carbon” goals and initiatives such as the Motor Energy Efficiency Improvement Plan are accelerating the market mainstreaming of high-efficiency, energy-saving motors. DC fan coil unit motors generally achieve IE4 or higher energy efficiency, fully aligning with policy requirements, and their penetration rate is expected to continue rising in new construction projects and in the retrofitting of existing equipment.
Growing demand in emerging applications: In addition to traditional central air-conditioning systems, high-end hotels, precision laboratories, and healthcare facilities—where quiet operation and precise temperature control are critical—are increasingly procuring permanent-magnet synchronous DC motors. Meanwhile, the widespread adoption of smart home technologies and energy-recovery ventilation systems is creating additional niche demands for DC fan-coil unit motors.
The industrial structure is gradually being optimized.
Accelerating domestic substitution: Leading Chinese companies such as Inovance Technology and Wolong Electric Drive are continuously achieving technological breakthroughs in areas like permanent-magnet materials and control algorithms, gradually narrowing the gap with international giants like Siemens and ABB. As a result, the share of domestically produced products in the high-end market will continue to rise.
Industrial Clustering and Regional Expansion: The agglomeration effects in the Yangtze River Delta and the Pearl River Delta will further intensify, while the central and western regions, supported by favorable policies and industrial chain relocation, are expected to outpace the national average growth rate. In addition, rising demand for high-efficiency, energy-saving motors in emerging overseas markets such as Southeast Asia and the Middle East will prompt domestically based companies with international certifications to accelerate their global expansion.
Products are evolving toward customization and integration: Downstream applications are placing increasingly diverse demands on motor size, speed, and noise levels, driving a continued rise in the share of customized motors—for example, compact DC motors tailored for ultra-thin fan coils will become more common. At the same time, the integration of motors and electronic controls is becoming a major trend; integrated control modules simplify system wiring, enhance compatibility with fan coils and central air-conditioning units, and reduce overall system failure rates.
