FAULHABER’s brushless dc 3274 BP4 is a servomotor with incredible torque density, measuring 32 mm in diameter and 74 mm in length, but with a continuous torque of 165 mNm. It weighs just under 320 grams, half the weight of conventional motors with comparable power.
The four-pole brushless dc servomotor is for applications in which high power and dynamic start/stop operation with the lowest possible total weight is an important factor. Perfect application fits 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. More after the jump.
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 (as in aerospace applications). This is made possible by a robust stainless steel housing and the omission of adhesives (common for assembly of other motors).
One feature of this motor series is flexibility: The FAULHABER series 3274 BP4 is equipped as standard with digital hall sensors. High-resolution optical and magnetic encoders attach 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.
