Our high power density motors feature flat wire windings for increased slot fill rate and improved power density—all in a compact form. Available in three series, they outperform traditional round wire motors in both efficiency and performance.
Santroll motor controllers are designed for precision, stability, and high compatibility across various motor types. With advanced algorithms and smart diagnostics, they ensure efficient, responsive control in electric vehicles, marine systems, drones, and industrial equipment.
Founded in 2001 as a micro-vehicle controller innovator, Santroll dominated China’s e-bike market (2003) and pioneered ultra-quiet brushless controllers (2004). Transitioning to hybrid buses (2009), it led China’s supercapacitor technology and achieved global-tier hybrid systems (2014). Shifting focus in 2017, Santroll developed cutting-edge flat wire motors—launching automated production (2020)—before its passenger car motor unit was acquired by BorgWarner for $220M (2022).
With over 700 employees and 1,233 patent applications, Santroll specializes in high power density motors and motor controllers. Our solutions power electric vehicles, ships, drones, rail systems, and more—built for performance, reliability, and customization.
Guided by the belief that “Limitless Technology Creates Unlimited Energy,” we continue to lead in the development of advanced electric drive technologies for a rapidly electrifying world.
Santroll provides a full-stack motor and controller development platform that takes designs from concept to production hardware. For motors, engineers combine structural design with high-fidelity electromagnetic, thermal, loss, efficiency, torque-ripple, demagnetization and NVH simulations, producing power-dense, quiet, highly efficient drives for demanding applications. For controllers, a model-based design flow with auto-code generation accelerates the path from control-algorithm prototype to production firmware. Mechanical and PCB layouts are co-developed with detailed electro-thermal and structural analysis to ensure power-density, reliability and EMC targets before prototyping. Cutting-edge SiC power devices boost switching efficiency, while Santroll’s patented Direct-Bonded-Copper plus Active Metal Brazing technology cuts thermal resistance, expanding junction-temperature headroom. The result is a compact, high-efficiency platform for e-mobility and industrial markets.
Santroll enforces quality from raw materials to finished systems: incoming magnets, conductors and machined parts are verified with Maxwell meters, resistance and hardness testers, precision deflection tools and 3-D CMMs, while in-line AOI, single-board tests, dynamic rotor balancing and winding-resistance checks police the build process. Completed products then face a full validation gauntlet—performance and NVH benches, tri-axis vibration/shock rigs, salt-spray, thermal-cycling and dust chambers, real-time vehicle dynos, and complete e-VTOL power-train rigs—guaranteeing every motor and controller performs flawlessly in the toughest automotive, industrial and aerospace environments.
Santroll pairs high-throughput electronics assembly with advanced motor manufacturing on a single campus. Our five fully automated SMT lines can place and solder 6 million components per shift, maintain a first-pass defect rate below 60 PPM, and run at more than 80 % utilisation, ensuring rapid, consistent production of motor-controller PCBs. On the electromechanical side, a dedicated, robot-driven line has achieved mass production of eight-layer flat-wire (hairpin) motors, giving us an annual capacity of 100,000 drive units.
Leveraging decades of automation expertise, Santroll offers turn-key motor-production solutions, assisting clients worldwide in planning, building, and optimising their own manufacturing lines.
Service offices in the United States, Germany, and Australia provide timely support across different time zones. A dedicated after-sales team ensures fast response to customer requests, offering technical guidance and troubleshooting. Regional parts warehouses support quick delivery of spare components, ensuring efficient service from installation to ongoing maintenance.
