Product Description:

Bosch Rexroth Indramat’s MKE118D-027-PG3-KE6 is part of the MKE Synchronous Motors series and operates as a servo motor for potentially explosive production zones. The model supports closed-loop torque and speed control for conveyor sections, mixers, or filling stations where flammable gases may be present. Integrated feedback and a fully encapsulated stator help the motor maintain stable motion profiles while staying within its thermal limits.

The motor delivers a continuous standstill torque of 48.0 Nm at a continuous current of 22.1 A when the winding temperature rise is limited to 60 K. For short-duty peaks, it can reach a maximum torque of 187.0 Nm, while the inverter may supply up to 99.6 A RMS to produce that surge. With proper field orientation, the rotor can spin at 3000 rpm, and the winding uses code 027 with 5.70 mH inductance and 0.350 Ω resistance for responsive operation. The electromagnetic design maintains a torque constant of 2.52 Nm/A and a back-EMF constant of 154.5 V per 1000 rpm, which helps keep controller voltage margins predictable. A discharge capacity of 20.2 nF and insulation class 155 F help limit partial discharges under fast-switching PWM, while the allowable ambient temperature range is 0 to 40 °C. Radiated acoustic energy is limited to 61.1 dB[A].

The rotor inertia is 0.03620 kgm², and the motor uses a plain shaft with a DIN 332 DS thread, a frontal centering hole, and a factory-fitted shaft seal. A holding brake rated at 70 Nm secures vertical or load-held axes during power loss. The aluminum housing meets ATEX requirements and has an enclosure rating of IP 65. Cable entries sized 17.0 to 19.5 mm exit through a top-mounted terminal box. The overall mass is 65.0 kg, and the upper cable orientation helps with routing in densely packed equipment bays.
