Product Description:

The MKE098B-047-DG0-BENN is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MKE Synchronous Motors series. It is intended for drive axes installed in potentially explosive zones where precise closed-loop motion is needed for conveyors, mixers, or filling equipment. This makes it suitable for hazardous production areas that still require accurate speed regulation and repeatable positioning. Mechanical power is transmitted through a plain shaft with a front centering hole, and electrical connections are oriented on the B-side of the housing to simplify armored-conduit routing in classified areas.

At a 60 K winding rise, the motor sustains a continuous torque of 12.0 Nm while drawing 9.8 A at standstill, allowing it to hold static loads without overheating. Transient moves are supported by a peak torque of 43.5 Nm backed by a permissible current of 44.3 A. The rotor can reach 4500 rpm, supporting medium-speed positioning tasks across indexing, transfer, and dosing applications. A torque constant of 1.41 Nm/A links drive current to developed torque, while a voltage constant of 91 V/1000 rpm supports inverter sizing for back EMF. Rotor inertia of 0.00430 kg·m² supports quick acceleration with limited overshoot, and the motor’s 1.20 mH inductance together with 8.400 Ω resistance influences current-loop response. Position feedback is delivered by an optical multi-turn EnDat 2.1 encoder with 2,048 increments for absolute position capture, so the controller can retain shaft position information without a homing move after startup.

The flameproof housing fulfills ATEX requirements and carries a shaft lip seal plus a 6.7 nF discharge path for electromagnetic compatibility. Permitted ambient operation is 0 to 40 °C, and insulation class 155 F allows elevated internal temperatures during cyclic duty. Acoustic output is limited to 61.8 dB[A], which helps reduce additional noise in enclosed work areas. The motor weighs 18.0 kg, giving it substantial thermal mass while remaining manageable during installation. A DIN 332 DS shaft thread facilitates secure coupling, and screw terminals inside the rear housing section permit straightforward loop-through when multiple drives share a power supply.
