Ask for AvailabilityThe Bosch Rexroth Indramat MKE118D-027-AG3-KI4 is a servo motor from the MKE Synchronous Motors series designed for use in potentially explosive areas, featuring an IP65 rating and optical encoder with 128 increments. It has a maximum torque of 187 Nm, operates with a continuous current of 22.1 A at standstill, and comes with a holding brake rated at 70 Nm. The motor weighs 65 kg without the brake, has a plain shaft with a frontal centering hole, and uses a terminal box connection at the top.
Internal Product Review
The MKE118D-027-AG3-KI4 is a servo motor for potentially explosive areas with IP65 protection. Continuous standstill torque of 48.0 Nm and peak torque of 187.0 Nm give this unit excellent overload capability for demanding axis control. A singleturn Hiperface optical encoder and 70 Nm holding brake support precise feedback and secure stopping, making the package a strong choice for hazardous-duty motion systems.

Product Description:
The MKE118D-027-AG3-KI4 is a servo motor built by Bosch Rexroth Indramat for the MKE Synchronous Motors series and classified for potentially explosive areas. It combines a flame-proof housing with feedback, power, and brake functions to drive axes that require strict safety measures in industrial automation cells, conveyors, and process equipment. The motor’s single-turn optical Hiperface encoder supplies position data to the drive controller so that closed-loop motion can be executed with the response expected from a high-performance synchronous design.
At a 60 K winding temperature rise, the unit sustains 48.0 Nm of standstill torque while drawing 22.1 A. These values indicate continuous stall capability during prolonged clamping or positioning cycles. The torque constant is 2.52 Nm/A, and winding code 027 uses 5.70 mH inductance with 0.350 Ω resistance. For short bursts, it can reach 187.0 Nm, and rotor speed is limited to 3000 rpm so centrifugal forces stay within mechanical limits. The voltage constant is 154.5 V/1000 rpm, and a discharge capacity of 20.2 nF helps electromagnetic compatibility at higher dv/dt. An ambient range of 0 to 40 °C and insulation class 155 F help keep thermal stress predictable. Weight without the brake is 65 kg, and acoustic output peaks at 61.1 dB[A].
A holding brake rated at 70 Nm secures vertical loads when power is removed. During acceleration, the drive may command up to 99.6 A before the protection system intervenes. The rotor inertia of 0.03620 kgm² balances dynamic response with load matching. All conductors enter through a terminal box on the top of the housing, and the cable gland spans 13 to 16 mm to suit armored leads common in hazardous zones. An IP 65 seal, a plain shaft with a frontal centering hole, a DIN 332 DS thread, and a fitted shaft seal protect the motor from dust and low-pressure water jets. Encoder model S1 supplies 128 increments per revolution, and the optical single-turn technology provides reliable feedback without batteries.
