basic information
● High Speed and High Acceleration The RDM-mini features a structure that minimizes the generation of eddy current losses through the adoption of coreless linear motors, lightweight sliders, and the use of resin materials, achieving a maximum speed of 5 m/s and an acceleration/deceleration of 9G. ● Lightweight and Compact The RDM-mini utilizes a compact linear motor, linear encoder, and LM guide with ball retainers (SHW12). By employing shielded flat cables for power and signal connections, it is a linear motor actuator with a small installation footprint, including cable routing. ● Low Speed Ripple and Excellent Uniformity With the adoption of a coreless linear motor, which features a rod shape where coils surround the magnets, there is minimal fluctuation in the electrical gap, resulting in extremely low thrust variation during operation. Additionally, by using LM guides with ball retainers that have low rolling resistance variation, low speed ripple has been achieved.
