FAULHABER Brushless DC-Servomotor 2264…BP4
FAULHABER has extended the powerful BP4 product family with the Brushless DC-Servomotor 2264…BP4. As well as having a good 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 product reaches up to 34,500 rpm. The reason for the high performance is the innovative segment winding of the coil, which was developed for the brushless DC motors of the BP4 family. Due 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.
There is also room for a resilient shaft with a diameter of 4 mm and suitable bearings due to the compact coil. With its low inertia, the motor is suitable for dynamic start/stop operation. The unit is also overload-resistant. It operates without wear-prone mechanical commutation and, as a result, has a service life longer than standard DC micromotors, according to the company. It can be used at temperatures of between -40 and +125°C.
Optionally integrated analog Hall sensors can replace an encoder in the majority of applications and determine the position of the output shaft precisely. Compatible optical and magnetic encoders are also available for high-precision applications.
Among other things, the motor is suitable for industrial automation and the handpieces of electric tools, eg, electric pruning shears and screwdrivers, motorised instruments for surgery, grippers and robots, and also for aerospace or for active prosthetics.
