Product Description:

The MKE118D-035-CP3-KE6 is a servo motor manufactured by Bosch Rexroth Indramat for the MKE Synchronous Motors series. Intended for automation in areas where explosive atmospheres may occur, the unit provides closed-loop rotary positioning and speed control to connected machinery used in process lines, filling systems, and assembly stations. Compliance with the ATEX housing standard and an approved ambient range of 0 to +40 °C allow installation in explosive zones.

Electrical data for continuous duty are anchored by a continuous standstill torque of 48.0 Nm and a continuous standstill current of 29.8 A at a 60 K winding temperature rise. The 035 winding code combines a torque constant of 1.87 Nm/A, an inductivity of 3.20 mH, and a winding resistance of 0.210 Ω to shape the current-speed profile, while the voltage constant is 114.5 V per 1000 rpm. The motor reaches 3000 rpm without field weakening and stores transient energy through a 20.2 nF discharge capacity embedded in the stator. Class F insulation, a shaft seal, and an IP65 enclosure guard the interior against conductive dust or spray. Power and feedback conductors enter through a 17.0 to 19.5 mm cable gland on the top-mounted terminal box, keeping connectors clear of floor debris. Acoustic output is limited to 61.1 dB(A) ±3.

Beyond the continuous region, the drive can deliver a peak torque of 187.0 Nm and accept up to 134.3 A RMS for acceleration. A rotor inertia of 0.03620 kg·m² balances fast response with stability, and the frame weight of 65.0 kg provides thermal mass. The integrated holding brake clamps the shaft with 70 Nm when power is removed, which is useful for vertical axes. Position data are supplied by an optical multiturn absolute Hiperface encoder, model M1, with 128 increments per revolution, so motion remains traceable after power cycles. A keyed shaft machined to DIN 6885 permits torque-tight coupling to gearboxes.
