MKE047B-144-CG1-AUNN
The Bosch Rexroth Indramat MKE047B-144-CG1-AUNN is a member of the MKE Synchronous Motors series and represents a high-precision permanent magnet servo motor tailored for demanding industrial automation environments. This Servo Motor for potentially explosive areas integrates a plain shaft with frontal centering hole and sealing ring, ensuring robust mechanical coupling. It features an optical Multiturn absolute Hiperface encoder (Encoder Model: M1) with 128 increments to deliver precise position feedback. The inclusion of a holding brake capable of 2.2 Nm holding torque enhances safety and positional stability during power-off conditions. Designed for continuous operation, this motor balances high torque density and compact form factor in a motor size 47 package.
The MKE047B-144-CG1-AUNN is engineered with an electrical winding of 144 turns optimized for a nominal voltage supply of DC 580–750 V. The number of pole pairs: 4 ensures smooth torque generation and low torque ripple. Its torque constant of 0.59 Nm/A yields a peak torque of 2.7 Nm at 5 A continuous current and supports a maximum current of 22.6 A for transient load demands. The motor’s insulation class 155 (F) materials maintain dielectric integrity up to 155 °C, while housing standard compliance UL/CSA certifies adherence to rigorous safety standards. Connection is facilitated via a terminal box with A-side connection direction, enabling straightforward wiring integration.
Operational performance is further optimized by the built-in holding brake, which achieves a 3 ms engagement time and 4 ms release time, ensuring rapid response in dynamic systems. The motor’s winding inductance of 1.8 mH contributes to smooth current transitions and reduced electromagnetic noise. With a mass of 5.5 kg, the unit delivers an excellent power-to-weight ratio, minimizing bearing loads and inertia-driven overshoots. The IP65 protection rating guarantees full dust ingress protection and resistance to low-pressure water jets, making it suitable for washdown and high-humidity conditions. The plain shaft design, complete with sealing ring, ensures long-term mechanical durability and simplified maintenance.
System integration is streamlined through compatibility with common servo drives and controllers designed for the MKE series, leveraging the motor’s Hiperface encoder for real-time feedback and closed-loop control. The encoder’s multiturn capability eliminates the need for external battery backups and reduces commissioning complexity. Target applications include printing machines, machine tools, packaging systems, and hazardous-area automation where intrinsic safety and precision are paramount. The comprehensive feature set of the MKE047B-144-CG1-AUNN motor makes it an ideal choice for engineers seeking reliable, maintenance-free performance in advanced motion control solutions.
