In the fight for high performance with minimum weight, the FAULHABER 3274 BP4 brushless dc servomotor stands out. It measures 32 mm in diameter and 74 mm in length and has continuous torque of 165 mNm. Plus, it weighs just under 320 g, which is half the weight of conventional motors with comparable power.
The four-pole, brushless dc servomotor fits applications in which high power and dynamic start/stop operation with the lowest possible total weight is an important factor. Such applications include humanoid robots, electric grippers used in process automation and high performance traction drives used in inspection robotics.
The 3274 BP4 is overload resistant and operates without wear-prone mechanical commutation. As a result, its 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. The 3274 BP4 can reliably deliver what the application demands even under the harshest ambient conditions, such as at low temperatures or high mechanical loads (in aerospace applications, for example). This is made possible by a stainless-steel housing and the omission of adhesives, which are otherwise usually used for assembly.
The servomotor is equipped with digital hall sensors. High-resolution optical and magnetic encoders can be attached with ease to the rear multifunction flange. As an option, the motor is also available with analog (linear) hall sensors that can replace an encoder in many applications. Finally, a large selection of optimal performance precision gearheads rounds off the complete drive system.
