Product Description:
The MKE118D-012-DG0-KE4 servo motor from Bosch Rexroth Indramat belongs to the MKE Synchronous Motors series. Intended for motion axes installed in potentially explosive zones, it converts drive commands into rotary motion while meeting ATEX housing requirements. A sealed terminal box on the top of the frame routes power and feedback leads, allowing integration into process lines that require precise positioning without creating sparking sources.
Under a 60 K winding temperature rise, the motor can deliver a continuous torque of 48.0 Nm while drawing a continuous standstill current of 13.0 A. When short-term overloads occur, the drive may supply up to 58.5 A, letting the shaft reach a peak torque of 187.0 Nm before current limiting intervenes. A torque constant of 4.29 Nm/A gives a linear relationship between phase current and developed torque, which helps keep servo control predictable. The 0.98 Ω winding resistance and 15 mH inductance determine the electrical response of the windings, and an optical multi-turn EnDat 2.1 encoder with 2,048 increments returns absolute position to the drive. Operation is permitted at ambient temperatures from 0 to 40 °C, and insulation class 155 F protects the stator against thermal aging.
The mechanical envelope permits a maximum speed of 2000 rpm, matching applications that balance torque with moderate rotational velocity. A rotor inertia of 0.03620 kgm² supports stable acceleration behavior, while the overall weight of 65.0 kg helps with vibration damping and heat absorption. An enclosure rating of IP 65 blocks dust and water jets, and a shaft seal supports that protection around the plain shaft with its frontal centering hole and DIN 332 DS thread. Cable entries ranging from 13 to 16 mm accept armored glands, discharge capacitance is 20.2 nF for electromagnetic compatibility, and the sound pressure level is 61.1 dB[A]. The motor is supplied without a holding brake, so vertical axes require external locking when power is removed.
