Robotics Joint Actuator Solutions — Micro Precision Drives

# Micro Drive Solutions for Robotics Joints **Precision gear motors for robot grippers, educational robots, and servo replacements.** ## The Challenge Robotics applications demand precision, repeatability, and torque density in the smallest possible package. Off-the-shelf hobby servos often lack the precision and reliability needed for serious applications. | Challenge | Why It Matters | Our Approach | |:---|:---|:---| | **Precision** | Joint positioning requires low backlash and repeatability | Planetary gears with <1° backlash | | **Torque Density** | Small robots need high torque in minimal space | N20 platform: 3.0 kg·cm in 12mm package | | **Position Feedback** | Closed-loop control is essential | Hall encoders (7/12 PPR) and magnetic encoders (up to 512 CPR) | ## Recommended Products | Product | Best For | Key Specs | FOB (1K+) | |:---|:---|:---|:---| | N20 Planetary Gear Motor | Small robot joints, grippers | 12mm, 1.0-3.0 kg·cm, <1° backlash | $3.80 | | BL-24C Slotless BLDC | Collaborative robot joints | 24mm, <30dB, zero cogging, 15K+ hrs | $15.00 | | N20 Worm Self-Lock | Robot gripper locks, brakes | 12mm, self-locking, fail-safe hold | $4.50 | ## Customization - Encoder integration: Hall 7/12 PPR or magnetic up to 512 CPR - Custom output shaft: D-cut, keyway, pinion gear - Dual-shaft configurations for through-frame mounting - FOC controller options for BLDC (CAN bus / RS485) - Custom gear ratios for specific speed/torque profiles [Request a robotics motor sample →](/contact)
