Product Description:
The MKE118D-035-BP3-KE6 is a three-phase synchronous servo motor produced by Bosch Rexroth Indramat within the MKE Synchronous Motors series. Designed for motion control in potentially explosive areas, it has ATEX-compliant housing and an IP65 enclosure that resists dust and low-pressure water jets. A terminal box on top of the frame houses the power and feedback leads, and the motor operates in ambient temperatures from 0 to +40 °C without additional cooling. The enclosed connection layout also helps keep wiring organized when the motor is installed on machinery with limited access around the drive end.
At standstill with a 60 K winding temperature rise, the motor can supply 48.0 Nm of continuous torque while drawing 29.8 A of continuous current, and these values remain within insulation class 155 F. For brief overloads, the windings can tolerate up to 134.3 A, allowing acceleration peaks of 187.0 Nm. The motor can reach 3000 rpm, and position is reported by a single-turn EnDat 2.1 optical encoder with 2,048 increments. A winding inductance of 3.20 mH and a winding resistance of 0.210 Ω shape the electrical response, while a voltage constant of 114.5 V per 1000 rpm matches the motor with compatible servo drives.
A spring-applied brake delivers 70 Nm of holding torque for vertical-axis retention, and the torque constant of 1.87 Nm/A provides a clear relationship between commanded current and produced torque. Rotor inertia is 0.03620 kg·m², which helps moderate acceleration when the motor is coupled to large loads. The frame mass is 65.0 kg without the brake, and the shaft uses a DIN 6885 keyway with an integrated shaft seal to support reliable power transmission and limit oil ingress. Cable glands sized for 17.0–19.5 mm conductors support shielded routing, while the top-side terminal box keeps connections away from lower machine surfaces that may be exposed to washdown.
