Product Description:
The MKE118D-027-NP0-KUN is a flame-proof servo motor built by Bosch Rexroth Indramat for the MKE Synchronous Motors series. It is intended for motion axes located in potentially explosive areas where an electric drive must supply closed-loop torque without generating hot surfaces or sparks. A terminal-box on the top of the housing provides power and feedback access, and the IP65 enclosure keeps dust and low-pressure water jets from reaching internal windings.
At standstill and with a 60 K winding temperature rise, the motor delivers a continuous torque of 48.0 Nm while drawing a continuous phase current of 22.1 A. Thermal behavior at this load is influenced by a winding inductivity of 5.70 mH, which limits di/dt during fast current transitions, and a phase resistance of 0.350 Ω measured at 20 °C, which determines copper losses. The enclosure carries an IP 65 rating, so routine wash-down or airborne particulate will not compromise insulation class F components. Mechanical output is transferred through a keyed shaft; there is a shaft seal, and the unit is supplied without a holding brake to avoid residual friction in hazardous zones.
Dynamic limits are higher: the rotor can generate up to 187.0 Nm for short accelerations and reach a shaft speed of 3000 min⁻¹ when the drive releases a maximum RMS current of 99.6 A. Those figures are moderated by a rotor inertia of 0.03620 kg·m², giving predictable response times for coupling to massive loads, and by a total mass of 65.0 kg that simplifies vibration isolation. A torque constant of 2.52 Nm/A and a voltage constant of 154.5 V per 1000 rpm relate electrical setpoints to mechanical output, while a 20.2 nF discharge capacity and a 61.1 dB(A) sound pressure level help define installation rules under UL/CSA guidelines and the 0 to 40 °C ambient range.
