Product Description:
The MKE118D-035-BG0-KE6 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MKE Synchronous Motors series. It is built for use in potentially explosive areas with an ATEX-compliant housing and is intended to provide precise torque in hazardous-zone automation. A built-in optical single-turn EnDat 2.1 encoder with model S2 and 2,048 increments supplies absolute position data to the drive controller, while a terminal box on the top of the frame provides access for field wiring.
At standstill, the motor can deliver 48.0 Nm of continuous torque with a corresponding continuous current of 29.8 A, and these values apply at a 60 K winding temperature rise. When higher short-term output is needed, torque rises to 187.0 Nm and current can reach 134.3 A RMS. The maximum speed is 3000 rpm, matching a torque constant of 1.87 Nm/A and a voltage constant of 114.5 V per 1000 rpm. Winding code 035 has an inductance of 3.20 mH and a resistance of 0.210 Ω, which affect current ripple and drive selection. The housing has an IP 65 rating, and insulation class 155 (F) supports elevated internal temperatures. The plain shaft includes a frontal centering hole and a DIN 332 DS thread, but the motor has no holding brake, so the load must be held in position by external means. A discharge capacitance of 20.2 nF helps divert transient charges through the grounding system.
The rotor inertia is 0.03620 kgm², which gives the motor a moderate balance between acceleration and speed stability. The overall mass is 65.0 kg, so mounting arrangements must account for the motor's weight. Operation is permitted from 0 to +40 °C. An integral shaft seal helps block dust and moisture during use. Sound pressure remains 61.1 dB[A] (±3) during rated service. Cable entry diameters from 17.0 mm to 19.5 mm suit armored glands used in Ex-rated panels, and the top-facing connection direction simplifies vertical motor installations.
