Full-range Self-Developed Product Matrix — SMARTWIN Intelligent Equipment, an Independent R&D Manufacturer of Torque Motors, Fills the Gap in Domestic Heavy-Duty Direct-Drive Technology

Against the backdrop of achieving independent and controllable industrial chains for high-end equipment, the market of integrated outer rotor torque motors with large hollow bore and heavy-load capacity has long been monopolized by overseas brands. Imported products are plagued by pain points such as long procurement lead times, high costs for non-standard customization and delayed after-sales technical support, which restrict the localized production of large rotary tooling equipment in China’s lithium battery, photovoltaic and semiconductor industries. With self-developed full-process technologies covering magnetic circuit design, winding manufacturing and complete machine assembly, SMARTWIN Intelligent Equipment has built a full product matrix of five standardized DDA outer rotor torque motor models. It fills the market vacancy of domestic integrated large-bore heavy-duty DD motors and accelerates the localization substitution of core rotary direct-drive components.

SMARTWIN Intelligent Equipment realizes full-chain independent R&D of DDA motors, including magnet layout, high-density windings, sealed housing and integrated encoder modules. The five models feature clear load classification: DDA112 and DDA140: Designed for compact precision light-load stations; DDA170: Suitable for medium-load standard indexing equipment; DDA220 and DDA263: Target heavy-duty tooling and long-stroke large rotary tables. The continuous torque ranges from 3 to 97 N·m with a maximum peak torque of 285 N·m, fully covering load requirements for most automated rotary equipment on the market. The core performance indicators match those of imported outer rotor torque motors of equivalent specifications. Boasting three core strengths — symmetrical magnetic circuits to counteract vertical magnetic pull, smooth operation with low cogging torque, and integrated encoders inside large hollow bores — the motors satisfy stringent operating requirements of high-end equipment, such as micron-level repeat positioning accuracy and 7×24-hour continuous mass production.

Each motor is factory-integrated with a cast base and high-precision encoder. Its standardized mounting references and electrical interfaces enable direct drop-in replacement for equivalent imported products. Equipment manufacturers are exempt from remolding or revising overall mechanical structures, which drastically cuts transformation costs and R&D cycles for import substitution.The complete motor can be matched as a full set with SMARTWIN AKS servo drives and grating encoders. The entire motion control solution is independently developed domestically, breaking free from supply lead time constraints of overseas core components.The semi-enclosed housing protection structure adapts to ordinary industrial workshop environments, featuring dust resistance and tolerance to high & low temperature fluctuations. Multiple aging tests conducted before delivery guarantee stable operation under mass production working conditions.

Localized manufacturing and regional technical services form the differentiated competitive edges of the DDA series. Standard models are kept in regular stock, and the delivery lead time for customized orders with minor adjustments to hollow bore size and torque parameters is greatly shortened. Local technical teams across regions can promptly handle requests including model selection calculation, structural integration and multi-axis synchronous commissioning, addressing industry pain points of overseas brands such as lengthy after-sales cycles and costly on-site service fees.At present, DDA outer rotor torque motors are mass-supplied to leading domestic automation equipment manufacturers, with applications covering segmented sectors including lithium cell processing rotary tables, photovoltaic silicon wafer inspection equipment, semiconductor wafer indexing platforms, and precision optical & medical instruments.Moving forward, SMARTWIN Intelligent Equipment will continuously expand the torque specifications of the DDA series and optimize high-speed dynamic control performance. With reliable, easy-to-integrate and cost-effective domestic outer rotor torque motors, we will keep bridging gaps in the high-end direct-drive industrial chain, and support domestic automation equipment to achieve full independent controllability of core motion control components.
