The world´s smallest brushless motor with integrated motion controller

The well-known BX4 family of brushless DC servo motors from Faulhaber has an innovative 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. 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 ideal for use in demanding application areas such as robotics, automation, medical technology, specialty machinery and the aerospace industry.

The drives are based on proven their motion control systems. With their compact, uniform-diameter construction and suitable gearing combinations, they provide the ideal 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 °C, thermally allowable continuous current up to 0.69 A, and flexibly configurable speed in the range of 5 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. Outstanding features of these innovative new products are an extremely flat torque versus speed curve and an excellent torque to volume ratio, with torque output of 18 to 35 mNm.
