Product Description:
The MKE098B-047-BG1-BENN is a servo motor built by Bosch Rexroth Indramat within the MKE Synchronous Motors series. Designed for use in potentially explosive zones, it drives position-controlled axes where ignition-source prevention is mandatory. The motor integrates an optical single-turn EnDat 2.1 encoder with 2,048 increments for closed-loop feedback and includes a holding brake that secures vertical or suspended loads when power is removed. A terminal box positioned on the B-side streamlines field wiring and allows the unit to be mounted without rotating the stator housing.
At standstill, the motor can deliver a continuous torque of 12.0 Nm while drawing 9.8 A under a 60 K winding temperature rise, giving stable force for indexing tables and dosing pumps. The stator winding code is 047, and the motor has an inductance of 1.20 mH, which affects current rise time and drive bandwidth. During rapid moves, speed can climb to 4500 rpm, and the associated back EMF is managed by drives sized for a voltage constant of 91 V/1000 rpm. Transient load surges are accommodated by a peak phase current of 44.3 A without compromising the Class 155 insulation.
The dynamic ceiling is a maximum torque of 43.5 Nm, which lets the motor handle short overloads typical of press feeders or spindle positioning. Motion response is aided by a rotor inertia of 0.00430 kgm², balancing acceleration and stability for medium-mass payloads. Acoustic emissions stay near 61.8 dB[A], simplifying compliance with plant noise limits. With the brake excluded, the frame weighs 18.0 kg, and an internal shaft seal protects the bearings when ambient temperatures range from 0 °C to +40 °C. The housing fulfills ATEX requirements, so explosion-proof cable glands and the B-side terminal box can be installed without additional enclosures.
