Product Description:
The MKE118D-058-NG1-KE4 is a servo motor for potentially explosive areas produced by Bosch Rexroth Indramat within the MKE Synchronous Motors series. In hazardous-zone automation, it converts drive current from the controller into controlled mechanical power so conveyors, mixers, or filling stations can run at commanded speed and torque while meeting ignition-risk regulations. A factory-installed holding brake maintains shaft position when the drive is de-energized.
This motor is housed in an enclosure rated at IP 65, which blocks dust and water jets so the frame can be washed down without harming internal windings. Its maximum mechanical output is 187.0 Nm, allowing high breakaway force when loaded shafts start from rest. A rotor inertia of 0.03620 kgm² moderates acceleration profiles so larger loads can be positioned without oscillation. Power and feedback cables enter through a gland range of 13.0 mm to 16.0 mm. The fittings are placed on the top of the housing, and the leads terminate inside a terminal box. The motor carries a weight of 65.0 kg, which affects mounting-surface rigidity and handling. Class F insulation rated at 155 (F) permits higher winding temperatures before thermal limits are reached. The plain shaft includes a frontal centering hole and a DIN 332 DS thread for coupling, while winding code 058 identifies the electrical resistance and inductance values used by the matching drive.
The permissible ambient range of 0...+40 °C suits typical operating conditions in process plants. A shaft seal is fitted to help keep oil or vapor from entering the bearing chamber, and operation meets 61.1 dB[A] sound pressure. Compliance with ATEX housing standards certifies the frame, gaskets, and cable entries for use in explosive dust or gas atmospheres, and the top-entry terminal design keeps conduit runs short when the motor is ceiling mounted. Winding 058 current characteristics remain unchanged across the stated temperature envelope.
