Product Description:

The MKE098B-047-KG0-BENN is a brushless servo motor produced by Bosch Rexroth Indramat for the MKE Synchronous Motors series. Engineered as a servo motor for potentially explosive areas, it uses an ATEX-compliant housing so it can operate in gas or dust zones that require ignition-protected equipment. Within an automation cell, it accepts commands from a drive controller and converts them into controlled torque and speed for positioning tasks on conveyors, mixers, or filling systems. This arrangement supports regulated motion in process equipment where hazardous-area compliance is required.

At a 60 K winding temperature rise, the motor draws a continuous current of 9.8 A, yielding a continuous standstill torque of 12.0 Nm. For short accelerations, the drive may supply up to 44.3 A, allowing the shaft to reach a peak torque of 43.5 Nm. The mechanical design supports speeds up to 4500 rpm, so rapid positioning can be carried out within an ambient range of 0 to +40 °C. A terminal box on the B-side handles power and feedback wiring, while the housing meets ATEX requirements for Zone 2 gas or Zone 22 dust locations. The motor is supplied without a holding brake, so static load retention requires external clamping, and nominal operation produces 61.8 dB[A] of sound pressure.

A torque constant of 1.41 Nm/A gives the relationship between phase current and produced torque, while a voltage constant of 91.0 V/min⁻¹ characterizes back EMF used by the drive for speed estimation. Dynamic response is aided by a rotor moment of inertia of 0.00430 kgm², which helps limit overshoot when coupled to low-mass loads. The motor has a total mass of 18.0 kg. The windings present 8.400 Ω of resistance and 1.20 mH of inductance, values that influence drive sizing and current-loop tuning. A plain shaft with a frontal centering hole, a DIN 332 DS thread, and a fitted shaft seal supports direct coupling while helping maintain enclosure integrity against oil or dust ingress.
