MKE047B-144-AG1-AUNN
The MKE047B-144-AG1-AUNN is a high-performance synchronous servo motor from Bosch Rexroth Indramat within the MKE Synchronous Motors series. This compact unit features a Motor Size of 47 and a Winding code of 144, delivering a nominal speed up to 7000 rpm for demanding applications. Weighing approximately 5.5 kg and equipped with a Plain shaft design complete with a sealing ring, it offers both a reduced footprint and robust mechanical integrity. As a specialized Servo Motor for potentially explosive areas, it complies with stringent safety and performance standards while maintaining high dynamic responsiveness. Engineered with an A-sided Connection Type via a terminal box and an A-side Connection Direction, it simplifies installation in complex machine architectures.
Technical prowess is exemplified by its integrated Optical encoder, Singleturn Hiperface system (Encoder Model S1) with 128 Encoder Increments, enabling precise position feedback. The motor’s Number of Pole Pairs is 4, delivering smooth torque with minimal ripple, and its rotor moment of inertia is optimized at 0.00017 kgm² for rapid acceleration and deceleration. With a Holding Brake featuring a Holding Brake Torque of 2.2 Nm, it secures loads instantly when de-energized. The unit’s Insulation Class of 155 (F) and Housing Standard Compliance to UL/CSA ensure thermal endurance and safety under continuous operation. The robust Shaft Thread conforming to DIN 332 and frontal centering hole provide straightforward mechanical coupling.
Operational integrity is reinforced by comprehensive brake characteristics: a rated voltage of 24 VDC and a holding brake current of 0.40 A delivers reliable actuation within 3 ms connection and 4 ms disconnection times, while the brake’s own moment of inertia of 0.000007 kgm² contributes negligibly to overall rotor inertia. Its discharge capacity rating of 1.6 nF safeguards downstream electronics from transient spikes. The design incorporates an IP65 protection rating for complete dust exclusion and water jet resistance, and the surrounding air temperature must be maintained between 0 °C and 40 °C to preserve peak performance. A shaft seal and plain shaft arrangement further guard against contamination and enhance service life in harsh environments.
Integration is streamlined through the A-sided terminal box interface, allowing direct connection to standard drive controllers and fieldbus systems. Its compatibility with the MKE Servo Motor Series accessories ensures seamless synchronization in multi-axis systems. Ideal for applications in machine tools, printing machines, and food-processing machinery, this motor excels where precision, safety, and reliability are paramount. With its explosion-protected construction and UL/CSA compliance, the MKE047B-144-AG1-AUNN provides a versatile solution for industrial automation in challenging environments.
