Product Description:
The MKE118B-024-HG0-KUN is a three-phase servo motor manufactured by Bosch Rexroth Indramat within the MKE Synchronous Motors series. It is designed to drive machine axes installed in potentially explosive areas where precise speed and torque regulation are required. The motor is supplied through a terminal box mounted on top of the housing, and its plain shaft with a frontal centering hole simplifies alignment to couplings or gear reducers. This layout keeps the electrical connection point accessible without changing the motor’s basic mounting form. The motor is supplied without a holding brake, so any static load must be held by external mechanical means.
Under continuous operation with a 60 K winding rise, the motor can sustain 28.0 Nm of torque while drawing a steady current of 15.3 A. For acceleration or short overload events, it reaches a peak torque of 102.0 Nm and a maximum mechanical speed of 4000 rpm. The electromagnetic design converts stator current into torque with a constant of 2.12 Nm/A, which helps the drive respond predictably to commanded current changes. During brief current surges, the winding can accept up to 69.1 A RMS before thermal limits are approached. The UL/CSA-compliant insulation system is rated to Class 155 F, and a discharge capacitance of 10.3 nF helps divert transient voltages to ground in converter-fed applications.
The motor’s dynamic profile is influenced by a rotor inertia of 0.01940 kgm², which balances quick acceleration with stable speed control on heavier loads. Copper losses during current flow are governed by a winding resistance of 7.60 ohms at 20 °C, while the low inductance of 0.580 mH supports fast current loops for servo precision. This helps the drive maintain responsive current regulation during rapid speed changes. Ambient operation is permitted from 0 to +40 °C. A shaft seal is present at the output end to minimize contamination ingress, and the recorded sound pressure level is 61.1 dB(A).
