Product Description:

The Bosch Rexroth Indramat MKE118D-027-AP0-KE4 is a servo motor for potentially explosive areas and belongs to the MKE Synchronous Motors series. Its ATEX-compliant housing, IP65 sealing, and the lack of a holding brake support operation where flammable gas or dust may be present. In automated lines, it can drive pumps, agitators, or positioning tables that require regulated torque and speed. The integrated single-turn Hiperface feedback gives the drive controller position data for closed-loop motion, while the sealed housing helps protect internal parts from dust and water spray.

With a 60 K winding temperature rise, the motor sustains 48.0 Nm while drawing 22.1 A, which is suitable for continuous duty. Short-term overload operation permits 99.6 A RMS and peak shaft torque up to 187.0 Nm for acceleration or process disturbances. Rated speed is 3000 rpm, so the motor can often be coupled directly without large speed reduction. The 027 winding uses a phase resistance of 0.350 Ω, an inductance of 5.70 mH, and a terminal-box capacitance of 20.2 nF. Insulation class 155 (F) and an ambient range of 0 to +40 °C support stable thermal operation in enclosed machinery.

Service wiring enters a top-mounted terminal box through 13–16 mm cable glands that preserve the enclosure rating and keep cable routing organized. Top cable entry can also help keep bends gentle near the housing. The optical S1 encoder supplies 128 increments per revolution for position regulation, and a keyed shaft to DIN 6885 with a shaft seal helps keep oil and particles away from the bearing set while limiting noise to 61.1 dB(A) ±3. Dynamic behavior is supported by a rotor inertia of 0.03620 kgm² and a torque constant of 2.52 Nm/A, which give the drive a predictable relationship between commanded current and produced torque. The motor also has a back-EMF constant of 154.5 V/min⁻¹. Its mass of 65.0 kg is suitable for either vertical or horizontal installation when the mounting structure is sized for the load.
