Product Description:
Bosch Rexroth Indramat manufactures the MKE118D-035-DP3-KE6 synchronous servo motor, which belongs to the MKE Synchronous Motors series. The unit is intended for use in potentially explosive zones where precise rotary drive is required for machinery such as mixers, agitators, or conveyor axes. By combining an ATEX-compliant housing with an integrated multi-turn feedback device, the motor supplies closed-loop position and speed control to automation systems without additional protective enclosures. This arrangement supports accurate motion in hazardous-area applications while keeping the drive package compact.
The electrical data set the main operating limits. At standstill and with a 60 K winding rise, the motor produces 48.0 Nm of continuous torque while drawing 29.8 A. The 035 winding has an inductance of 3.20 mH and a resistance of 0.210 Ω at 20 °C; with these values, the torque constant reaches 1.87 Nm/A, and the back EMF constant is 114.5 V per 1000 rpm. Speed regulation covers 0 to 3000 rpm, and the inverter may supply up to 134.3 A RMS during acceleration. A multi-turn optical EnDat 2.1 encoder, model M2, delivers 2,048 increments for fine positioning, while a discharge capacity of 20.2 nF helps reduce bearing current spikes. Thermal endurance relies on class 155 F insulation, and ingress protection is rated IP65.
Peak dynamics reach 187.0 Nm of torque, supported by a holding brake that clamps the shaft with 70 Nm when the drive is de-energized. The rotor inertia of 0.03620 kgm² balances quick acceleration with load stability, while the overall mass of 65.0 kg helps damp vibration and store heat. Mechanical coupling is through a keyed shaft made to DIN 6885, and a shaft seal is fitted to help block dust and splashes. Power and feedback wires enter through a top-mounted terminal box that accepts 17.0–19.5 mm cable glands. The motor operates between 0 °C and +40 °C, emits 61.1 dB(A), and uses a flameproof enclosure for hazardous-location service.
