China’s Permanent Magnet Synchronous Motor Drive Industry: Innovation, Scale, and Global Leadership
In the global race toward electrification, energy efficiency, and intelligent automation, few components are as strategically critical as the Permanent Magnet Synchronous Motor (PMSM) and its associated drive system. China has emerged not merely as a manufacturing powerhouse but as a global innovation leader in this field, with a robust ecosystem of manufacturers that spans every application—from heavy-duty mining trucks and commercial vehicles to precision robotics and wind energy systems. This article provides an in-depth exploration of China’s PMSM drive manufacturing industry, highlighting its scale, technical capabilities, and the visionary companies driving its global expansion.
The Strategic Importance of PMSM Drives
Permanent Magnet Synchronous Motors represent the pinnacle of modern electric propulsion technology. Their unique design—using rare-earth permanent magnets embedded in the rotor to generate a constant magnetic field—delivers superior power density, higher efficiency (frequently exceeding IE5 levels), and exceptional torque control compared to induction or brushed motors. When paired with an advanced motor drive (controller), the PMSM system becomes a “smart muscle,” capable of translating digital commands into precise, responsive mechanical motion.
The drive system—often referred to as the “brain and nervous system” of the motor—controls voltage, current, and frequency to optimize performance under varying loads. China’s manufacturers have developed sophisticated drive technologies supporting multiple control algorithms (V/F control, open-loop vector control, and closed-loop vector control) that enable speed regulation ratios exceeding 1:200 for PMSMs, torque response times under 5 milliseconds, and zero-speed hovering capability at 150% torque. These technical achievements allow Chinese PMSM drives to compete with, and often surpass, their international counterparts.
A Diverse and Dynamic Industrial Landscape
China’s PMSM drive manufacturing industry is characterized by remarkable diversity, ranging from large-scale public companies with multi-billion RMB revenues to specialized “little giant” enterprises focusing on niche applications.
Market Leaders and Scale Players
Zhejiang Founder Motor Co., Ltd. stands as one of the industry’s veterans. Founded in 1995, the company has successfully transformed from a traditional motor manufacturer into a core automotive components supplier, covering the full spectrum of new energy vehicles—passenger cars, commercial vehicles, and beyond. With cumulative shipments of nearly 3.3 million new energy drive motors by the end of 2024, Founder Motor supplies major OEMs including SAIC-GM-Wuling, Geely, SAIC Motor, Chery, Xiaopeng, Li Auto, Leapmotor, and Volkswagen. Their product portfolio includes permanent magnet synchronous motors, AC induction motors, switched reluctance motors, and comprehensive motor controllers, demonstrating the breadth of capability required to serve the global automotive industry.
Ningbo Physis Technology Co., Ltd. takes a different strategic approach, positioning itself as a comprehensive “electrical drive solutions provider” covering both industrial automation and new energy vehicles. Physis provides integrated solutions spanning three layers: the control layer (the “brain”), the drive layer (the “joints”), and the execution layer (the “muscles”). According to CIC (China Industry Consulting), Physis is one of the few Chinese manufacturers capable of delivering such fully integrated, multi-layer solutions. Their products have been deployed in extreme applications including the ALMA radio telescope project, which captured the first image of a black hole—a testament to the precision and reliability of Chinese PMSM drive technology.
Specialized Innovators: The “Little Giant” Champions
China’s industrial policy has fostered a generation of “specialized and sophisticated” (专精特新) enterprises that dominate specific market segments. Suzhou Longo Motor Technology Co., Ltd. exemplifies this trend. Recognized as a National High-Tech Enterprise, National Specialized and Sophisticated “Little Giant” Enterprise, and holder of a National Postdoctoral Research Station, Longo Motor has accumulated over 220 authorized patents and operates a CNAS (China National Accreditation Service for Conformity Assessment) accredited testing laboratory.
The company’s market position is formidable: according to Frost & Sullivan statistics, Longo Motor held over 70% market share in China’s new energy mining truck drive motor sector by sales volume in 2025, ranking first in the industry. It also ranked second in new energy heavy-duty truck drive motors with approximately 28% market share, while maintaining strong positions in new energy bus motors and wind power pitch motors. With revenues growing from RMB 385 million in 2023 to RMB 1.447 billion in 2025—an 88% year-on-year increase—Longo Motor demonstrates the explosive growth potential of specialized PMSM manufacturers.
The company’s technical innovations include flat-wire motor technology (60-400kW covering multiple application scenarios), oil-cooling solutions (improving power density by over 30%), and proprietary IP68 protection structures for commercial vehicle applications. Their “zero-defect” quality philosophy, supported by full-chain quality control from design through supply chain and manufacturing, has earned them the trust of industry partners across China and beyond.
Shenzhen Hengdrive Motor Co., Ltd. represents another successful “little giant.” As a subsidiary of Foxconn Technology Group and a National Specialized and Sophisticated “Little Giant” Enterprise, Hengdrive focuses on BLDC and PMSM motors with integrated drive controllers—a proprietary technology that reportedly places them 2-3 years ahead of domestic competitors. Their product range spans 36 standard series covering powers from 0.1W to 10KW and diameters from 16mm to 300mm, with monthly production capacity reaching 1.2 million units. Hengdrive has successfully supplied automotive components to major OEMs including Li Auto, Xiaopeng, NIO, Dongfeng Lantu, GAC Aion, Geely Zeekr, Changan Deepal, and BYD.
Ningde Contemporary Electric Technology Co., Ltd. took an early lead in new energy vehicle motor technology. In 2008, they pioneered the introduction of permanent magnet high-efficiency motor design technology into China’s domestic new energy vehicle sector, making them one of the country’s earliest manufacturers of new energy vehicle motors and key components. Their extensive operational experience across vehicles and vessels has given them deep insights into the reliability requirements of diverse applications.
Technical Excellence Across Multiple Dimensions
Chinese PMSM drive manufacturers have achieved technical excellence in several critical dimensions:
High-Power Density and Thermal Management
The industry has made significant strides in power density improvement through advanced cooling technologies. Longo Motor’s oil-cooling and oil-water composite cooling solutions increase power density by over 30% compared to conventional designs. Harbin Electric’s advanced motor company has achieved breakthroughs in high-speed, high-power-density PMSM drive systems, innovatively adopting a “gearless” direct-drive architecture that eliminates the gearbox for improved efficiency and reliability.
Wide Power and Voltage Coverage
Chinese manufacturers serve applications ranging from fractional horsepower motors (0.1W) to multi-megawatt industrial systems. INVT Electric’s GD350A series drives, for example, cover power ranges from 1.5kW to 500kW, supporting permanent magnet synchronous motors, asynchronous motors, and synchronous reluctance motors with flexible control algorithms. This versatility enables a single manufacturer to serve diverse industries from material handling to wind power.
Precision Control and Customization
Advanced control technologies are now standard across the industry. Closed-loop vector control delivers dynamic speed drop below 0.25%, speed overshoot under 5%, and torque response under 5ms. Companies like Zhejiang Hiatran Electric Technology—located in Hangzhou and leveraging the industrial technology background of Zhejiang University—specialize in ferrite-assisted synchronous reluctance motors achieving IE5 ultra-high efficiency levels. These motors, which use high-temperature-resistant and low-cost ferrite magnets, represent a strategic move to reduce reliance on expensive rare-earth materials while maintaining exceptional efficiency.
