SMARTWIN Intelligent Equipment, a Frameless Torque Motor Manufacturer, Breaks Bottlenecks in Integrated Design of High-End Equipment

For the design of high-end equipment including semiconductor indexing stages, precision medical imaging rotary tables, optical inspection tooling and special automated instruments, miniaturized complete machines, integrated structures and deep embedded installation inside equipment cavities have become mainstream design trends. Conventional housed finished torque motors are restricted by their outer casing dimensions, making them difficult to fit into compact equipment cavities. Moreover, they cannot match manufacturers’ self-developed structures such as sealing assemblies, hollow cable routing and bearing support frames. As a domestic professional manufacturer specializing in the independent R&D and mass production of frameless torque motors, SMARTWIN Intelligent Equipment has launched the DBM series frameless torque motors. The products only supply split core components (stator and rotor), allowing equipment manufacturers to implement embedded internal integration on their own. Featuring low cogging torque and high torque density derived from optimized magnetic circuits, the DBM series serves as the preferred domestic direct-drive solution for customized high-end rotary equipment.

The electromagnetic design of DBM frameless torque motors leverages finite element magnetic field simulation to optimize skewed magnet pole arrangement and dense winding layout. This fundamentally mitigates cogging effects and drastically suppresses low-speed torque ripple. When equipment operates under working conditions such as micro-angle fine-tuning and low-frequency reciprocating indexing, speed fluctuation is kept to a minimum, delivering smooth, jitter-free rotation that fully satisfies stringent demands including micro-angle wafer positioning, optical lens focusing adjustment, and high-precision angular rotation of medical equipment. In addition, high-density windings boost torque density. The motors deliver outstanding torque output under identical radial installation dimensions, balancing high-speed operation with dynamic performance of instantaneous high acceleration and deceleration. They can keep pace with production rhythms featuring rapid product changeovers and high-frequency station switching on flexible production lines. Electrically, the entire series adopts standard high-voltage insulated windings with ample insulation withstand voltage margin, enabling long-term compatibility with industrial high-voltage servo power supply systems.

The split frameless structure represents the core highlight of the DBM series. By eliminating the integrated housing, equipment manufacturers are allowed to independently design bearing seats, flange bases, protective casings and hollow inner bores according to their own equipment cavity space, hollow through-hole wiring requirements, workshop cleanliness classes and dust-proof & sealing standards, which greatly maximizes the freedom of mechanical structural design. Compared with housed DD motors that require reserved mounting space for complete units, the frameless solution minimizes the overall equipment footprint and truly integrates the motor into the mechanical structure of the complete machine. The rigid direct-drive connection to the load completely eliminates backlash, elastic hysteresis and long-term wear-induced precision drift caused by reducers and timing belt transmission. Load following performance is drastically improved. In addition, regular replacement and lubrication maintenance of transmission components are no longer required, effectively cutting the full-lifecycle operation and maintenance costs of equipment.

All products undergo rigorous reliability verification procedures prior to delivery. Every set of stator and rotor assemblies passes winding withstand voltage testing, alternating vibration durability testing, and high-low temperature cycle aging testing, which fully guarantee magnetic circuit performance and insulation stability. Relying on SMARTWIN Intelligent Equipment’s advantages in localized R&D and manufacturing, we provide rapid customized development to meet customers’ special requirements including customized torque parameters, hollow inner diameters, cleanroom-grade windings and low electromagnetic interference. The lead time for non-standard customized products is far shorter than that of imported frameless torque motors from overseas. In addition, professional technical engineers offer full-process technical guidance covering structural integration, bearing selection and dynamic balance calibration. At present, DBM frameless torque motors have been mass-supplied to numerous domestic manufacturers of semiconductor equipment, precision medical devices and optical inspection instruments. With embedded high-performance direct-drive capabilities, the DBM series makes up for supply chain gaps in domestically-produced high-end customized rotary actuator components.
