Shaanxi Jiebang’s Self-Fed Iron-Core-Free Permanent Magnetic Coupling technology has been officially certified by the China Energy Conservation Association, achieving an internationally leading level in coupling magnetic circuit design. As an innovative achievement in the interdisciplinary field of magnetic machinery, the technology originates from rigorous physical principles rather than conventional large-team iterative research, delivering simplified design and superior inherent magnetic transmission performance. Two customized couplets precisely summarize its core strengths of zero inter-shaft force, zero iron loss and flexible buffering, echoing the brand’s commitment of trouble-free shaft connection.
Traditional American mutually-fed magnetic coupling technology, once widely applied and highly praised, has inherent fatal flaws: problematic inter-shaft force causing over 50% of industrial transmission failures and shaft damage; severe iron loss including eddy current and hysteresis loss leading to high energy consumption and heat generation; and invalid soft-start & unreliable torque limiting functions that interfere with equipment protection.
Targeting these industry pain points, Jiebang has defined three core criteria for high-quality couplings: no rotor mutual attraction, ultra-low energy loss, and reliable flexible buffering. Its proprietary self-fed iron-core-free technology thoroughly solves industry drawbacks: it generates torque only in the rotating direction with zero inter-shaft force; eliminates iron loss fundamentally to boost efficiency by 2% above national standards; and features convenient installation, no strict rotor alignment requirement and automatic failure damage control for safer, low-maintenance operation.
Compared with domestic and foreign mutually-fed products, Jiebang’s technology achieves all-round superiority in safety, energy efficiency and practicability. A 5000t/d rotary kiln renovation project verified its remarkable economic value: the client savesRMB 240,000 annually on failure costs, realizes maintenance-free operation and completely eradicates oil leakage. The technology has been reported by CCTV’s Rising China and Our New Era for its outstanding innovation value.
Filling domestic industry standard gaps, Jiebang led the formulation of the group standard T/CI 002-2022, which first establishes systematic testing methods for inter-shaft force, quantifiable flexible indicators and energy loss calculation models for permanent magnetic couplings, guiding the standardized upgrading of the industry.
Adhering to high-quality and independent R&D development since 2013, Jiebang refuses copycat manufacturing, builds a full-process quality control system, and consolidates technological differentiation via continuous R&D and core patents. Insisting that reasonable design is the foundation of quality assurance, the company advocates identifying genuine industrial innovation via standards, practice and data to drive high-quality industrial development.
Moving forward, Jiebang will continue to deepen technological innovation with physically optimal design concepts, providing safer, more efficient and more reliable industrial transmission solutions, and strive to showcase the strength of Chinese technological innovation globally.
