Internal Product Review
The MKE118B-024-BP0-KE4 is a Bosch Rexroth Indramat servo motor for potentially explosive areas with ATEX housing compliance. Standstill performance is especially impressive, with 28.0 Nm continuous torque at standstill and 102.0 Nm maximum torque for demanding motion profiles. Singleturn EnDat2.1 optical encoder feedback and 4000 min⁻¹ maximum velocity make the unit a very capable choice for precise hazardous-area servo applications.

Product Description:
The MKE118B-024-BP0-KE4 belongs to the MKE Synchronous Motors series from Bosch Rexroth Indramat and is a servo motor for potentially explosive areas. This configuration is intended for controlled motion in hazardous locations where flammable gases or dust may be present. Its ATEX-compliant housing allows operation in these zones, and the unit is intended for ambient temperatures from 0 to +40 °C. A terminal box on the top of the frame accepts power and feedback lines through 13–16 mm cable glands. The shaft has a DIN 6885 keyway and a shaft seal, and the motor is supplied without a holding brake. The motor also has insulation class 155 F and a sound pressure level of 61.1 dB(A).
At standstill with a winding temperature rise of 60 K, the motor can deliver 28.0 Nm of torque while drawing 15.3 A. These continuous values come from winding code 024, which pairs a resistance of 7.60 Ω with an inductance of 0.580 mH for stable current control. The torque-to-current constant is 2.12 Nm/A, and velocity regulation is supported up to 4000 rpm. Position data are generated by an optical S2 single-turn EnDat 2.1 encoder with 2,048 increments per revolution, and the encoder gives the drive precise single-turn position feedback for closed-loop operation. A discharge capacitance of 10.3 nF aids electromagnetic compatibility, and the voltage constant is 130.0 V/1000 rpm, which affects back EMF at speed.
For short-term demands, the drive may reach 102.0 Nm and an RMS phase current of 69.1 A, which provides added headroom during acceleration in explosive-zone machinery. Dynamic response benefits from a rotor inertia of 0.01940 kg·m², which helps limit overshoot when the motor is coupled to low-mass loads. Mechanical stability is supported by a weight of 45.0 kg, and the sealed shaft helps prevent lubricant migration into the hazardous area. The motor is suited for pumps, mixers, and handling axes installed in ATEX-classified production areas.
