CJM050 Series Iron-Cored Linear Motors: High-Efficiency Drive Solution for Compact Precision Equipment

Against the backdrop of automation equipment trending toward miniaturization and high precision, the CJM050 series iron-cored linear motors launched by Dongguan Smartwin Intelligent Equipment Co., Ltd. have emerged as the preferred drive solution for precision applications in confined spaces, thanks to their compact design and outstanding performance. Built on the core of iron-cored technology, this series balances high acceleration response with operational stability, delivering reliable power support for precision equipment in industries such as 3C electronics and semiconductors.

The core advantage of iron-cored linear motors lies in the balanced optimization of thrust density and structural efficiency. The CJM050 series inherits this feature with its iron-cored design. By optimizing the magnetic circuit structure, it achieves low cogging force output, effectively minimizing thrust ripple during operation and ensuring smooth performance even when the equipment is running at high speeds. Meanwhile, the tight integration of the iron core and coil significantly enhances electromagnetic conversion efficiency, unleashing powerful driving force within a compact footprint. Combined with its ultra-thin and ultra-short structural design, the motor perfectly fits small-space installation requirements, addressing the long-standing pain point of "large size with low efficiency" associated with traditional motors.

The CJM050 series also excels in key performance metrics. Its mover length ranges from 96mm to 176mm, with continuous thrust spanning 117N to 234N and peak thrust reaching up to 370N to 740N, fully meeting the dynamic demands of high-frequency movements and rapid positioning in compact equipment. Boasting excellent dynamic response capability, the motor’s high-acceleration characteristic enables faster start-stop switching of equipment. In addition, a maximum allowable operating temperature of 100°C and a thermal dissipation coefficient of 0.6W/°C ensure stable operation during prolonged high-frequency use.

Compared with similar products, the core competitiveness of the CJM050 series lies in its balanced design that achieves "small size with high performance". Its compact dimensions allow seamless integration into the interior of small precision equipment, while the low cogging force design ensures operational stability, preventing jitter-induced deviations in precision operations. In contrast to ball screw drives, the direct linear drive eliminates mechanical transmission gaps, achieving higher positioning accuracy. Moreover, the contact-free operation eliminates wear and tear, and the maintenance-free feature reduces equipment operation and maintenance costs. When compared with ironless linear motors, the CJM050 series offers superior thrust density, delivering stronger power output within the same installation space.

In terms of application scenarios, the CJM050 series is precisely tailored to meet the requirements of high responsiveness in confined spaces. In the 3C electronics industry, it is ideal for processes such as micro-connector assembly and component transfer in small SMT pick-and-place machines, leveraging its high acceleration response to enable high-frequency precision operations. In the field of micro-components, it is suitable for scenarios including MEMS sensor assembly and surface-mount device inspection, where its low cogging force characteristic guarantees the precision of inspection and assembly processes. In the semiconductor industry, it fulfills the demands of precision operations such as wafer fragment handling and chip pin inspection, providing reliable driving support for the refined manufacturing processes in semiconductor production.
