Product Description:
The MKE118D-027-BP0-KE4 belongs to the MKE Synchronous Motors series from Bosch Rexroth Indramat and is supplied as a servo motor for hazardous areas. Its housing meets ATEX requirements, allowing installation in zones where flammable gas or dust may be present. The motor drives rotary axes in automated equipment by converting controlled three-phase current into precise shaft motion. This arrangement supports accurate speed and position control in demanding industrial applications.
At a 60 K winding temperature rise, the motor sustains 48.0 Nm of standstill torque while drawing 22.1 A. Rated data are tied to winding code 027, which uses 5.70 mH inductance and 0.350 Ω resistance together with a torque constant of 2.52 Nm/A and a voltage constant of 154.5 V per 1000 rpm. The S2 optical encoder provides 2,048 increments through a single-turn EnDat 2.1 interface for position feedback. The terminal box is arranged for top entry, the cable gland accepts cable diameters from 13 to 16 mm, and the capacitance is 20.2 nF. The enclosure is rated IP65, the shaft is fitted with a seal, insulation class 155 F is used, and continuous operation is permitted up to 3000 rpm when the ambient temperature remains between 0 °C and +40 °C. Mechanical output is transmitted through a shaft with a DIN 6885 keyway, and the motor is supplied without a holding brake.
During acceleration, the drive may reach 187.0 Nm of torque while the inverter must supply up to 99.6 A RMS. Dynamic response is influenced by a rotor inertia of 0.03620 kg m², which supports stable motion under changing load conditions. The bare motor weighs 65.0 kg, adding thermal mass that slows temperature rise during demanding cycles. These ratings apply when the top-entry terminal box is sealed, the shaft seal is in place, and the housing is properly grounded for ATEX service.
