In the fight for high performance with the lowest possible weight, Faulhaber has unveiled a brushless DC servo motor with the development of its 3274 BP4 series. It measures 32 mm diameter and 74 mm length and provides a continuous torque of 165 mNm. With just under 320 g it weighs less than half than conventional engines with comparable performance. The four-pole motor is ideal for applications that require high performance and dynamic start / stop operation with the lowest total weight.
Such applications can be found, for example, in joint drives of humanoid robots, electric grippers in process automation or high-performance drive drives for inspection robotics. The 3274 BP4 is overloadable and works without wear-prone mechanical commutation. It achieves an operating life that is many times higher than that of a conventional DC micro motor. The slope of the motor characteristic is only 3 rpm / mNm at a stall torque of 2,7 Nm. Even under the harshest environmental conditions, such as low temperatures or high mechanical loads such as aerospace, the 3274 BP4 can deliver reliably whatever the application demands. This is ensured by, among other things, a sturdy stainless steel housing and the absence of the usual use of adhesives during assembly.
By default, the 3274 BP4 series is equipped with digital Hall sensors. High-resolution optical and magnetic encoders can be easily attached to the rear multifunction flange. Optionally, the motor is also available with analog (linear) Hall sensors, which can replace an encoder in many applications. In addition, a large selection of precision gearboxes is available for the performance-optimized rounding of the complete drive system.
