Smartwin Dual-Sided Iron-Core Linear Motor Truly Eliminates Guideway Wear
Traditional iron-core linear motors have long faced an inherent physical paradox in heavy-load applications: higher thrust inevitably generates stronger normal attractive force, which aggravates guideway wear and degrades motion smoothness. Adopting a disruptive dual-sided symmetrical magnetic circuit design, Smartwin Intelligent Equipment completely decouples the strong correlation between thrust and vertical attractive force. Taking the CFB035, CFB050 and CFB065 series as examples, the continuous thrust ranges from 41N to 651N, with a peak thrust up to 1758N. It achieves nearly zero vertical attractive force under all operating conditions. The symmetric arrangement of iron cores on both sides counteracts the normal magnetic attraction mutually, leaving the guideway to bear only the actual load, which greatly improves service life and reliability. Meanwhile, magnetic flux utilization efficiency is significantly enhanced. Compared with single-sided motors of the same volume, the thrust density is increased by over 40%. Combined with advanced cogging force suppression technology, it realizes jitter-free operation even at low speed or micro-motion mode, providing fundamental physical guarantee for high-precision positioning and high-speed response.

In engineering implementation, Smartwin dual-sided iron-core linear motor adopts a full modular design. The mover and stator can be freely combined to form a rich specification matrix. The mover offers four length options: A (80 mm)、B (144.8 mm)、C (209.6 mm)、D (274.4 mm). The stator has two standard lengths: L128 (128 mm) and L192 (192 mm). Stator width increases by model: CFB035: 35 mm, CFB050: 50 mm, CFB065: 65 mm. Users can flexibly match mover–stator combinations according to actual load, installation space and travel requirements. For vertical axis applications, a shorter mover can be selected to reduce overhanging torque; for long-travel horizontal axes, multiple stators can be spliced together. Featuring a compact structure, it supports multiple mounting methods for horizontal and vertical axes. It also delivers strong anti-interference performance, adapting to complex industrial electromagnetic environments such as welding and high-power electrical scenarios. This refined parameter system greatly reduces equipment integration difficulty, providing on-demand selection and plug-and-play drive solutions for lithium battery, semiconductor, laser processing and other industries.

With quantifiable performance indicators and flexible selection parameters, Smartwin dual-sided iron-core linear motors have proven their superiority in multiple heavy-load automation scenarios. In the lithium battery industry, the CFB065 is applied to heavy-duty cell handling on large PACK production lines. With a peak thrust of 1758N and near-zero attractive force characteristics, it extends guideway service life by more than 30%. In the semiconductor industry, the CFB050 delivers low jitter thanks to cogging force suppression and high repetitive positioning accuracy, ensuring yield consistency for large wafer handling equipment.
In laser processing, the CFB035 features high dynamic response to realize high-speed and high-precision cutting of thick metal plates. In heavy-duty assembly lines for automotive parts, the high thrust output of the CFB065 easily handles workpiece handling at the hundred-kilogram level. For equipment integrators, the modular combination of movers and stators with multi-size options greatly shortens the development cycle. For end users, low maintenance requirements and long-term operational reliability significantly reduce the Total Cost of Ownership (TCO).
With parametric and serialized dual-sided iron-core linear motors, Smartwin Intelligent Equipment redefines the performance benchmark for heavy-duty linear drive systems, providing solid technical support for China’s high-end manufacturing in the field of automation core components.
