Faulhaber 3274 BP4 brushless DC servo motor for robots, grippers

Apr. 24, 2015 – The Faulhaber 3274 BP4 brushless DC servo motor from Micromo measures 32 mm in diameter and 74 mm in length, and promises to deliver continuous torque of 165 mNm. The four‐pole servo motor is best suited for applications such as humanoid robots, electric grippers used in process automation, and high‐performance traction drives used in inspection robotics. The company says the 3274 BP4’s operational lifetime is many times longer than that of a conventional DC micro motor. The slope of the motor characteristic curve is just 3 rpm/mNm, with a stall torque of 2.7 Nm. Promising to be overload‐resistant, it equipped as standard with digital hall sensors. High‐resolution optical and magnetic encoders can be attached to the rear multifunction flange.
