MKE098B-047-DG0-BUNN

The Bosch Rexroth Indramat MKE098B-047-DG0-BUNN synchronous servo motor from the MKE Synchronous Motors series provides a robust, high-performance solution for precision drive applications. Designed without a holding brake, this unit features a plain shaft with sealing ring and a high-resolution 098 encoder delivering 2,048 increments per revolution. Engineered for continuous operation, the actuator develops a maximum torque of 43.5 Nm with a continuous standstill current of 9.8 A and a peak RMS current of 44.3 A. Comprehensive UL/CSA housing compliance ensures reliable protection in standard industrial environments, while the UL/CSA-rated terminal box and B-side connection direction simplify integration into existing motor control systems.

The MKE098B-047-DG0-BUNN is built around a 98 mm frame (Motor Size: 98) and weighs 18.0 kg without brake, offering an optimal power-to-weight ratio for medium-duty drives. The motor’s DIN 332 compliant 'DS' thread shaft and integrated shaft seal deliver secure coupling and environmental protection, and the robust housing meets UL/CSA standards for flammability and electrical safety. Connection is handled via a dedicated terminal box on the B-side, facilitating straightforward wiring and service access. This servo motor is classified as a "Servo Motor for potentially explosive areas," making it suitable for demanding installations where safety and reliability are paramount.

Operationally, the device must be transported within a temperature band of –20 °C to +80 °C and an ambient climatic category of 2K2, per DIN EN 60721-3-2, with strict avoidance of salt mist to prevent corrosion. If stored for one to five years without use, a no-load run at 800–1,000 rpm for one hour is required to maintain bearing integrity. Protective sleeves on the shaft and plug connections safeguard critical components during shipping and must be removed immediately before assembly. To preserve performance and mechanical accuracy, radial and axial forces must never exceed the manufacturer’s specified limits during handling and operation.

System integration is streamlined by the motor’s compliance with industry-standard mounting interfaces and flange dimensions, which accept M10 x 30 DIN 912 screws tightened to 51 Nm. The absence of a holding brake simplifies the mechanical design and reduces maintenance overhead in continuous-motion installations. Trained personnel should handle all installation and electrical connections, ensuring the system is de-energized and protected against accidental restart. Target applications include automation in chemical processing, oil and gas processing, and other industries requiring explosion-protected drive solutions where precise torque control and compliance with hazardous-area requirements are essential.
