The flyweight that packs a heavyweight punch

FAULHABER has extended the extremely powerful BP4 product family with the brushless DC-Servomotor 2264…BP4. As well as having an outstanding ratio of torque to size and weight, the miniature drive comes with integrated sensors and a wide speed range.

The 4-pole motor achieves a torque of 59 mNm with a weight of just 140 g and a diameter of 22 mm. Furthermore, the 2264…BP4 reaches up to 34,500 revolutions per minute. The reason for the outstanding performance is the innovative segment winding of the coil, which was developed for the brushless DC-Motors of the BP4 family. Thanks to the overlapping, nested, individually wound segments, an especially large amount of copper can be accommodated in the coil. The high winding symmetry with minimal losses and appropriately high efficiency is a desirable side effect.
