Product Description:

The MKE118D-035-DG0-KUN is a Bosch Rexroth Indramat servo unit offered in the MKE Synchronous Motors series. Classified as a servo motor for potentially explosive areas, it supplies regulated rotary power to conveyors, mixers, and positioning tables that must meet hazardous-location rules. Its housing follows UL/CSA directives, and the sealed IP65 enclosure resists dust and splashing fluids, enabling direct mounting in process lines without a separate cabinet.

During continuous stall duty, the motor sustains 48.0 Nm with a winding current of 29.8 A, allowing stable torque at a 60 K thermal rise. The torque constant of 1.87 Nm/A relates drive output directly to phase current, while the 0.03620 kg·m² rotor inertia moderates speed transients during acceleration and deceleration. Peak demands are covered by a maximum torque of 187.0 Nm and an RMS overload ceiling of 134.3 A. The 035 winding has an inductance of 3.20 mH and a resistance of 0.210 Ω, which influence current ripple and drive sizing. A voltage constant of 114.5 V per 1000 rpm indicates the generated back EMF level, and a 20.2 nF discharge capacity aids EMC grounding. Feedback is supplied by an M2 optical multi-turn absolute EnDat 2.1 encoder with 2,048 increments, giving position data across the full speed range.

The shaft is plain with a DIN 332 DS thread, a front centering hole, and a shaft seal, so couplings can be fitted without additional machining. Connections exit through a top-mounted terminal box, simplifying vertical cable runs and keeping cable routing straightforward in upright installations. Operation is permitted from 0 to +40 °C, and the unit reaches 3000 rpm for high-throughput cycles. Sound pressure is 61.1 ±3 dB(A). The motor uses Class F insulation, comes without a holding brake, and weighs 65.0 kg. The 55 mm stack adds thermal mass for continuous-duty operation.
