Product Description:
The MKE118D-027-BG0-KUN belongs to the MKE Synchronous Motors series produced by Bosch Rexroth Indramat. Classified as a servo motor for potentially explosive areas, it converts drive output from compatible controllers into rotational motion where ignition-protected equipment is required. A terminal box mounted on the top of the housing provides power and feedback terminations, and the unit is intended for ambient temperatures from 0 to +40 °C. This arrangement keeps the electrical connections enclosed and supports protected cable routing in enclosed machine installations.
During continuous operation at a 60 K winding temperature rise, the motor delivers 48.0 Nm while drawing 22.1 A, which indicates the continuous standstill load it can sustain thermally. For short acceleration bursts, the shaft can produce 187.0 Nm with an RMS current of 99.6 A. The electromagnetic design yields a torque constant of 2.52 Nm/A and a back-EMF constant of 154.5 V per 1000 rpm. These values are associated with winding code 027, a 5.70 mH phase inductance, and 0.350 Ω resistance measured at 20 °C. The motor also has a discharge capacitance of 20.2 nF for proper grounding of inverter-generated common-mode voltage. The housing follows UL/CSA construction rules, uses class 155 (F) insulation, and comes without a holding brake.
The shaft can spin up to 3000 rpm, a speed supported by a rotor inertia of 0.03620 kg·m² that balances dynamic response with load damping. Overall weight is 65.0 kg, and the enclosure carries an IP65 rating plus a shaft seal to block dust and water jets. A plain shaft with a frontal centering hole and a DIN 332 DS thread simplifies coupling alignment. Sound pressure during nominal running is 61.1 dB(A) ±3 dB. Position data are supplied by an optical single-turn EnDat 2.1 encoder with 2,048 increments, allowing accurate feedback for closed-loop speed and position control.
