Product Description:

The MKE118D-035-CP3-LUN belongs to the MKE Synchronous Motors series from Bosch Rexroth Indramat. It is a servo motor for hazardous areas that converts electrical energy into controlled rotary motion in automated machinery. This allows the motor to support positioning and speed-regulated motion where ignition-protected equipment is required. The unit is UL/CSA-compliant, uses an IP65 housing, and is intended for ambient temperatures from 0 to +40 °C. A left-oriented terminal box provides power and signal entry, and a keyed shaft that follows DIN 6885 transfers torque directly to couplings or gear stages.

Winding code 035 sets the electrical characteristics, including a continuous current at standstill of 29.8 A and a continuous standstill torque of 48.0 Nm at a 60 K motor case rise. The winding resistance is 0.210 Ω at 20 °C, the inductance is 3.20 mH, the voltage constant is 114.5 V min⁻¹, and the torque constant is 1.87 Nm/A. Under dynamic demand, the RMS current may reach 134.3 A, and the drive can deliver up to 187.0 Nm of peak torque, which helps during acceleration and short load surges. Maximum mechanical speed is 3000 rpm, and the rotor moment of inertia is 0.03620 kg m² for balanced acceleration behavior with matched loads. The motor uses an optical multiturn absolute Hiperface encoder, model M1, with 128 increments for closed-loop feedback, and its capacitance is 20.2 nF for EMC control.

The unit is supplied with a holding brake that produces 70 Nm of static torque for secure position retention during power loss. This brake helps keep the axis from drifting when the motor is not energized. Additional protective features include a sealed shaft and insulation class 155 (F), while operating sound pressure is 61.1 ±3 dB[A]. Encoder leads exit in the same direction to support orderly cable routing. The total mass without the brake is 65.0 kg, which should be considered during axis sizing and installation.
