Product Description:
The Bosch Rexroth Indramat MKE098B-047-AG0-BENN belongs to the MKE Synchronous Motors series. It is a servo motor for potentially explosive areas and is intended for actuators, mixers, or positioning axes that must meet ATEX housing requirements in hazardous production zones. The motor converts controlled electrical input into precise rotary motion so the connected axis can follow commanded speed or position with consistent accuracy. A terminal box on the B-side routes power and feedback conductors, and the plain shaft with a frontal centering hole supports direct coupling to gear stages or load hubs without additional keys. An optical single-turn Hiperface encoder with 128 increments, a DIN 332 DS shaft thread, and a fitted shaft seal are also included.
During continuous operation at a 60 K winding temperature rise, the motor sustains 12.0 Nm of torque while drawing 9.8 A. This operating point suits applications that need stable output over extended running periods rather than short bursts of overload. For rapid indexing or acceleration, the motor can reach 43.5 Nm of peak torque, and the rotor can spin up to 4500 rpm before velocity limiting is required. The electromagnetic design provides a torque constant of 1.41 Nm/A at 20 °C, so commanded phase current can be related directly to output torque during closed-loop control. These values describe the load range that the drive must observe during duty-cycle planning.
The permissible ambient temperature range of 0 to +40 °C allows mounting on machine frames in standard indoor plants. A mass of 18.0 kg adds stiffness to the axis, and that weight should be considered when sizing brackets or support plates. Rotor inertia of 0.00430 kg·m² supports smooth speed control with moderate acceleration capability, which can help reduce abrupt motion changes in driven equipment. For brief overloads such as startups against static friction, the power stage may deliver up to 44.3 A RMS without exceeding insulation class 155 (F). The ATEX-compliant housing and shaft seal help limit the entry of oil or dust during long operating periods.
