The BX4 family of brushless DC servo motors from Faulhaber recently welcomed a new member. With a 22 mm module, the 2232/2250 BX4 CSD/CCD is the world's smallest brushless motor with integrated motion controller in uniform-diameter construction, according to the company.  It combines all the advantages of BX4 technology in a tiny package: long service life, high non-cogging torque and freedom from adhesives. This makes them suitable for use in demanding application areas such as robotics, automation, medical technology, specialty machinery and the aerospace industry. The drives are based on Faulhaber motion control systems. With their compact, uniform-diameter construction and suitable gearing combinations, they provide the drive solution for a wide variety of applications. The drives have serial RS232 or CAN interfaces and can be configured using Faulhaber Motion Manager 4.4 software. Additional features of the new drives further expand their scope of use: a wide temperature range of -25 to +85 degrees C, thermally allowable continuous current up to 0.69 A, and a configurable speed in the range of five to 8000 rpm. The units are also available with customer-specific software on request. All products with integrated electronics have automatic peak and continuous current limitation to protect the motor and the electronics. Operation of the motor and the electronics from separate supply voltages is possible as an option. The new drives are available in two motor lengths (32 and 50 mm) with a rated voltage of 24 V DC.
