Product Description:

The MKE118B-024-PP1-KUN is a servo motor built by Bosch Rexroth Indramat for the MKE Synchronous Motors series. It is intended for use in potentially explosive areas, where closed-loop motion control is required for equipment such as conveyors, mixers, and filling stations. A factory-installed holding brake rated at 32 Nm helps prevent unintended shaft movement when power is removed. All wiring exits through a terminal box on top of the housing, which can simplify cable routing in vertical machine layouts.

At a 60 K winding temperature rise, the motor produces a continuous torque of 28.0 Nm while drawing 15.3 A. These values indicate the sustained load the motor can carry during normal operation. For short-duty peaks, torque rises to 102.0 Nm and current rises to 69.1 A, so the connected drive must supply the required current without nuisance trips. The motor reaches a mechanical speed of 4000 rpm, providing headroom for direct coupling to pumps or geared stages. A torque constant of 2.12 Nm/A relates commanded current to shaft torque, which helps the controller estimate load response. The 024 winding is paired with 0.580 mH inductance and 7.60 Ω resistance, which affect current-loop response and the voltage behavior during deceleration.

The rotating assembly has a moment of inertia of 0.01940 kg·m², giving the axis moderate acceleration capability without making light mechanical structures overly reactive. The steel-bodied enclosure weighs 45.0 kg before the brake is installed and follows UL and CSA construction rules, while an IP54 shaft seal helps block dust and splashing water at the shaft entry point. During steady operation, emitted sound pressure averages 61.1 dB[A], which can help keep machine noise within common plant targets. Ambient operation from 0 °C to +40 °C, insulation class F, and a discharge capacity of 10.3 nF round out the motor’s thermal and electrical characteristics.
