KGG Major New Product Launch

------PRCMQ Micro Precision Finger Actuator Unlocks New Potential for Micro-Actuation in Humanoid Robots

Recently, KGG officially launched a new product in its PRCMQ series of micro precision finger actuators.
This integrated drive-and-control micro-linear actuator addresses pain points in micro-actuation—such as those found in humanoid dexterous hands and bionic actuators—by highly integrating the motor, transmission, sensors, and drive control. With a compact, millimeter-scale body, it achieves micrometer-level motion control and thrust output in the hundreds of newtons, providing a high-performance, domestically produced drive solution for the fields of embodied intelligence and precision manufacturing.

The PRCMQ series features a built-in hollow-cup motor, precision ball screw, dual position sensors, and a drive-control chip, enabling fully closed-loop, precise displacement control. The product features an ultra-thin cross-section design measuring 11.5 mm × 14.5 mm, is available in two body lengths (59 mm and 65 mm), has a standard stroke of 16 mm, and supports custom stroke lengths to accommodate diverse installation requirements in confined spaces.

In terms of core performance, the new product features a repeatability of ≤0.02 mm and an absolute positioning accuracy of ≤0.1 mm; it delivers a maximum thrust of 120–150 N and a no-load speed of 35–50 mm/s. Electrical specifications support a wide-voltage power supply of 9–14 V (standard 12 V DC) with a maximum current of 1 A. It utilizes UART 3.3 V LVTTL serial communication, and no-load noise is ≤65 dB(A), ensuring quiet operation.

Compared to similar products, the PRCMQ offers four key advantages.

First, its integrated drive and control system enables extremely simple deployment; with a built-in drive and control unit, no external driver is required—it is ready to operate immediately upon wiring, effectively saving internal space and reducing overall integration costs.

Second, it features micrometer-level dual-mode control, supporting both point-to-point positioning and high-speed tracking modes to meet the demands of demanding applications such as precision assembly and high-accuracy positioning;

Third, it features a compact body with high torque density. Leveraging a multi-slot pole motor and high-slot-fill-ratio manufacturing processes, the unit’s overall volume is 21% smaller than that of comparable products;
