FM2 Robotic High Torque Density Frameless Motors

FM2 Robotic High Torque Density Frameless Motors

●  Introduction

HONPINE FM2 Frameless Torque Motors for Robotics offer higher performance and more configuration options compared to the FM1 series, making them suitable for a wider range of applications. Motor losses are reduced by 20%, while torque output is increased by 10% compared to FM1 motors, resulting in extended operating endurance.
The FM2 series is available in six diameters ranging from φ50mm to φ127mm, with rated speeds from 1800 rpm to 5500 rpm, torque ranging from 0.36 Nm to 6.40 Nm, and power output from 207 W to 608 W. Rated voltages range from 24 V to 70 V. Optional configurations include Hall sensors, temperature sensors, and customizable lead wire options.These motors are widely used in collaborative robots, humanoid robots, quadruped robots, industrial robots, and medical rehabilitation robots.
