Product Description:
The MKE118D-035-NG0-KE4 is a servo motor for potentially explosive areas produced by Bosch Rexroth Indramat within the MKE Synchronous Motors series. It supplies controlled rotary motion to pumps, agitators, or conveyors installed in zones that require ATEX-certified housings, and its insulation system is rated to class 155 (F). This design suits machinery used where combustible dust or vapor may be present. An ambient temperature range of 0 °C to +40 °C supports normal operating conditions. The motor comes without a holding brake, uses a top-mounted terminal box for power and feedback leads, and accepts cable entry diameters from 13.0 mm to 16.0 mm.
The motor provides a continuous standstill torque of 48.0 Nm at a continuous phase current of 29.8 A with winding code 035. These values support low-speed torque production while staying within the motor’s continuous thermal range. A rotor moment of inertia of 0.03620 kg·m² supports stable speed regulation while limiting acceleration demand on the drive. Peak output reaches 187.0 Nm, and the corresponding RMS current limit is 134.3 A. This reserve supports short acceleration demands before continuous ratings become the limiting factor. The torque constant at 20 °C is 1.87 Nm/A, and the maximum speed is 3000 rpm. Electrical characteristics include a winding resistance of 0.210 ohms, an inductance of 3.20 mH, and a discharge capacitance of 20.2 nF, which affects drive-side dV/dt filtering. Sound pressure during rated operation is limited to 61.1 dB[A] (±3).
The enclosure has an IP 65 rating, which protects the motor against dust and water jets. A shaft seal is fitted to protect the plain shaft, which also has a frontal centering hole and a DIN 332 DS thread. This arrangement helps limit contaminant entry at the output end. The back-EMF constant is 114.5 V/min⁻¹, giving the controller a predictable voltage reference across the speed range. Terminal conductors exit upward to match the specified connection direction. The complete assembly weighs 65.0 kg.
