Product Description:

The MKE118D-035-DP0-LUN is a servo motor built by Bosch Rexroth Indramat for the MKE Synchronous Motors series. It is a servo motor for potentially explosive areas, so it can drive positioning or process axes where flammable gases may be present. The motor integrates into automation cells that require precise torque delivery while meeting safety requirements for hazardous zones.

The electrical winding code 035 pairs with a torque constant of 1.87 Nm/A, relating current to mechanical output. At a 60 K temperature rise, the motor can sustain 48.0 Nm of torque while drawing 29.8 A, supported by a 3.20 mH phase inductance and a 0.210 Ω winding resistance that help limit ripple and loss. Transient demands are handled by a peak capability of 187.0 Nm, and speed control extends to 3000 rpm. A voltage constant of 114.5 V/1000 rpm aligns the motor with compatible inverters. Position feedback is delivered by an optical multiturn EnDat 2.1 encoder, type M2, that reports 2,048 increments per revolution and provides absolute position across multiple turns without battery support. The motor also has a discharge capacity of 20.2 nF, and airborne noise remains 61.1 dB[A] ±3 during nominal operation.

The unit operates between 0 °C and +40 °C and carries an IP65 enclosure rating, so dust ingress and water jets do not affect operation. A left-mounted terminal box simplifies cable routing, and UL/CSA housing approval supports installation in North American panels. Peak line current can reach 134.3 A during acceleration, a value moderated by the rotor's 0.03620 kg·m² inertia for controlled dynamic response. The motor has a shaft seal, a shaft with a DIN 6885 keyway, and no built-in holding brake. Insulation class 155 F materials support the windings under high thermal loads, while overall mass is 65.0 kg without the brake.
