Product Overview
The PM1105 (GB1105) is a compact and lightweight brushless gimbal motor designed for micro-scale precision applications. With a diameter of just 16mm and extremely low weight, it is ideal for robotic fingers, dexterous hands, and miniature actuation systems. The motor supports an optional AS5048A magnetic encoder for accurate position feedback.
