SMARTWIN Intelligent Equipment DBM Frameless Torque Motors Fill the Domestic Supply Gap for Embedded Direct-Drive Components
As the strategy of realizing independent and controllable high-end precision equipment continues to advance, frameless torque motors serve as core components for embedded rotary direct-drive systems. For a long-time, the high-end market has been heavily reliant on overseas brands. Imported products come with multiple practical pain points: exorbitant procurement costs, customized lead times stretching for months, technical blockades, slow after-sales response, and costly supporting commissioning services. These bottlenecks have directly restricted the pace of domestic upgrading and iteration for high-end equipment in the semiconductor, medical, scientific research and inspection sectors. SMARTWIN Intelligent Equipment is a local enterprise specializing in full-chain independent R&D of direct-drive components. Drawing on self-developed magnetic circuit design, winding manufacturing techniques and complete reliability verification systems, the company has developed the DBM series frameless torque motors. Delivering hardware performance comparable to imported counterparts, along with localized delivery and full technical support, the DBM series accelerates comprehensive domestic substitution of embedded frameless torque motors.

SMARTWIN Intelligent Equipment realizes in-house independent production covering all processes of DBM frameless torque motors, including magnet material selection, core lamination stacking, winding fabrication and insulating encapsulation. All core technologies are fully mastered internally, eliminating reliance on overseas magnetic circuit solutions and special winding raw materials. The core performance indicators of the products are benchmarked against world-leading frameless DD motors. The low cogging torque design ensures smooth torque output at low speeds, while high torque density delivers high torque output within compact dimensions. The high-voltage insulation system meets the requirements of long-term continuous industrial operation. The zero-backlash direct-drive transmission structure guarantees superior positioning rigidity and repeat positioning accuracy of the system. The motors can fully replace imported products for application scenarios with stringent motion performance requirements, such as wafer indexing rotary stages, VT imaging rotating gantries and high-precision optical angle measuring equipment. The mechanical mounting dimensions and electrical winding interfaces are directly compatible with imported products of identical specifications. Equipment manufacturers do not need extensive revisions to mechanical drawings and electronic control programs during replacement, drastically cutting transformation costs and R&D investment for domestic substitution.

Apart from matching imported products in hardware performance, the localized supporting ecosystem constitutes the irreplaceable competitive advantage of the DBM series. The complete frameless motor can form a full domestic motion control solution paired with SMARTWIN’ s self-developed SAR absolute circular grating encoders and AKS series bus servo drives. High-speed synchronous communication via the EtherCAT bus enables multi-axis linkage for precision indexing. The drives embed cogging torque compensation algorithms to further optimize smoothness during low-speed operation. All hardware and software of the complete system are independently controllable, eliminating risks such as protocol licensing restrictions and chip supply disruptions. When addressing customers’ non-standard customization requirements, whether it involves adjusting torque gradients, modifying hollow bore diameters, reworking low-particle windings for cleanrooms, or applying special treatments for electromagnetic interference suppression, SMARTWIN can rapidly deliver finished products relying on its in-house production lines, with far higher delivery efficiency for customized orders than overseas brands. Technical teams stationed at service outlets across multiple regions nationwide can provide on-site support for equipment manufacturers, including stator and rotor assembly, dynamic balance calibration, servo parameter tuning, and closed-loop system commissioning. This resolves the pain point of imported products, which only offer remote email guidance without on-site technical support.

In terms of working condition adaptability and long-term reliability, DBM frameless torque motors can be customized with targeted optimizations for various operating environments. Low-outgassing insulation treatment is available for high-temperature equipment; reinforced winding potting processes are adopted for devices subject to heavy vibration, catering to differentiated application scenarios of high-end equipment. Before delivery, all units undergo multiple rigorous reliability tests including 72-hour full-load continuous burn-in, temperature cycling shock and vibration fatigue testing, guaranteeing stable long-term operation after mass integration into machinery. Currently, DBM frameless torque motors have been mass-incorporated into the supply chains of leading domestic automation equipment manufacturers. Moving forward, SMARTWIN Intelligent Equipment will continuous expand its torque specification portfolio and optimize frameless structures featuring large hollow bores and ultra-thin profiles. With domestically manufactured frameless torque motors boosting high reliability, cost competitiveness and rapid service response, SMARTWIN will keep supporting domestic high-end precision equipment to achieve full independence and controllability over core motion control components.
