The four-pole brushless DC servomotor is ideal where high power density and dynamic start/stop operation with the lowest possible total weight is an important factor in applications such as humanoid robots, aerospace, process automation or high-performance traction drives in inspection robotics.
Weighing just 320 g which is half the weight of conventional motors with comparable power!
The 3274 BP4 is overload-resistant and brushless resulting in extended operational lifetime when compared to conventional DC motors. The rare earth magnets and high copper density of the new coil construction mean the slope of the motor characteristic curve is exceptionally flat at just 3 rpm/mNm resulting in a very strong motor performance across the entire speed range and culminating in a huge stall torque of 2.7 Nm.
The robust construction, stainless steel housing and omission of adhesives in the assembly process means the 3274 BP4 can reliably and consistently deliver peak performance in the harshest ambient conditions, such as at low temperatures or high mechanical loads (e.g. in aerospace applications).
One particularly interesting feature of this motor series is the high flexibility in its design. The FAULHABER series 3274 BP4 is equipped as standard with digital hall sensors. High-resolution optical and magnetic encoders can be attached simply to the rear multifunction flange. As an option, the motor is also available with analogue (linear) hall sensors that can replace an encoder in many application cases. Finally, a large selection of performance-optimised precision gearheads rounds off the complete drive system, distributed exclusively on the UK by EMS Ltd.
