Coreless rod type linear motor actuator
Due to the coreless structure, no suction force occurs between the forsa (movable part) and the magnet rod (stator). Additionally, because coils are arranged around the entire circumference of the magnet rod, the efficiency of magnetic flux utilization is increased.

basic information
● High Speed and High Precision Direct drive eliminates lost motion and backlash. Additionally, full closed-loop control using optical linear encoders enables high-speed and high-precision operation. ● High Acceleration and Deceleration By minimizing the mass of the slider (moving part), acceleration of 2G is achievable. A fin-integrated housing has been adopted to enhance heat dissipation. ● Low Speed Ripple The coreless structure eliminates cogging force, ensuring smooth operation even at low speeds. ● Multi-Slider Multiple sliders can be installed on a single axis, allowing for independent control of each slider. ● Maintenance-Free The adoption of LM guides with ball retainers enables long-term maintenance-free operation. ● Low Noise and Low Dust Generation The combination of linear motors and LM guides with ball retainers achieves low noise and low dust generation during operation.
