Product Description:

The MKE118D-027-BG0-KE6 is a three-phase AC servo motor built by Bosch Rexroth Indramat for the MKE Synchronous Motors series. Designed for potentially explosive areas, the unit supplies accurately regulated mechanical power to pumps, mixers, and conveying axes where combustible gases may be present. Its ATEX-compliant housing, terminal-box connection, and top-mounted cable entry simplify installation inside sealed enclosures, while the plain shaft with a frontal centering hole integrates with standard couplings. An optical single-turn EnDat 2.1 encoder and winding code 027 provide position feedback and electrical characteristics matched to compatible Rexroth drive controllers.

At standstill with a 60 K winding rise, the motor can deliver 48.0 Nm of continuous torque while drawing a continuous phase current of 22.1 A. This combination indicates its sustained load capability during holding or low-speed operation. The electromagnetic conversion efficiency is indicated by a torque constant of 2.52 Nm/A, so the drive can estimate torque from commanded current. When the field-oriented control loop releases the shaft, mechanical speed may reach 3000 rpm. The housing is sealed to IP65, helping protect internal components from dust and water jets in washdown production zones.

For transient acceleration, the rotor can produce up to 187.0 Nm of peak torque with a momentary phase current of 99.6 A. These limits affect inverter sizing and short-term overload behavior. The rotor has a moment of inertia of 0.03620 kg·m², which balances dynamic response with load smoothing in indexing or stirring applications. The housing weight of 65.0 kg requires secure mounting and appropriate lifting support. All ratings apply within an ambient range of 0 to 40 °C, and because the motor has no holding brake, the load must be secured by external means during a power loss.
