Product Description:

The MKE118D-035-CG0-KUN is a three-phase servo motor produced by Bosch Rexroth Indramat for the MKE Synchronous Motors series. Classified as a motor for potentially explosive areas, it serves as the prime mover for valves, mixers, and conveyor drives that must hold accurate speed and torque under hazardous-area requirements. A Class 155 (F) insulation system and a flame-proof housing rated to UL and CSA standards allow the unit to tolerate the thermal stress expected in continuous industrial service.

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 29.8 A. The torque constant is 1.87 Nm/A, so each ampere supplied by the inverter produces predictable mechanical output. For short-duty peaks, the motor can reach a maximum torque of 187.0 Nm and can accept up to 134.3 A RMS, while its rotor inertia of 0.03620 kg·m² helps moderate acceleration transients. A top speed of 3000 rpm suits packaging, filling, and pump applications that require rapid indexing, and the electrical data also includes a voltage constant of 114.5 V per 1000 rpm, a winding resistance of 0.210 Ω, a discharge capacity of 20.2 nF, and winding code 035.

The enclosure carries an ingress protection rating of IP65, and the permitted ambient temperature range is 0 to +40 °C. Power and feedback conductors are routed upward because the connections are on top of the terminal box. A plain shaft with a frontal centering hole, a DIN 332 DS thread, and an installed shaft seal simplifies coupling to gearboxes. The motor weighs 65.0 kg and produces only 61.1 dB[A] of sound pressure. Magnetic data includes a winding inductance of 3.20 mH and encoder feedback from an optical M1 multiturn absolute Hiperface unit with 128 increments. The design omits a holding brake, and the explosive-area approvals remain intact.
