Product Description:
The MKE118D-012-CG3-KE6 is a three-phase servo motor manufactured by Bosch Rexroth Indramat for the MKE Synchronous Motors series. Classified as a servo motor for potentially explosive areas, it meets ATEX housing requirements and is intended to drive position-controlled axes in hazardous-zone machinery where precise torque delivery and feedback are required. The integrated optical multi-turn absolute Hiperface encoder with model M1 and 128 increments supplies position data to the drive controller, allowing the motor to maintain accurate closed-loop motion throughout automated processes.
At a 60 K winding temperature, the motor supplies a continuous torque of 48.0 Nm while drawing 13.0 A at standstill. During acceleration, it can reach a maximum torque of 187.0 Nm with a peak RMS current of 58.5 A. The winding code 012 corresponds to an inductance of 15.000 mH and a resistance of 0.98 Ω at 20 °C. Its rated mechanical speed is 2000 rpm, and the encoder resolution is fixed at 128 counts per revolution. A discharge capacity of 20.2 nF helps minimize common-mode currents between the stator and the frame during pulse-width-modulated operation.
The motor has a torque constant of 4.29 Nm/A, which supports predictable output across the speed range, and the back-EMF constant is 263.5 V/min⁻¹ for drive sizing. Dynamic response is aided by a rotor inertia of 0.03620 kgm², and load holding during power-off states is provided by a brake rated at 70 Nm. The motor weighs 65 kg without the brake and operates in ambient temperatures from 0 to +40 °C. A sealed plain shaft with a frontal centering hole, a DIN 332 DS thread, and a shaft seal supports IP65 protection. Power enters through a terminal box on the top of the housing, and the cable gland accepts diameters from 17.0 mm to 19.5 mm. Insulation class 155 (F) withstands internal heating, and airborne noise does not exceed 61.1 dB(A).
