Product Description:
The MKE118B-058-CP0-KE4 servo motor is manufactured by Bosch Rexroth Indramat and belongs to the MKE Synchronous Motors series. Classified for potentially explosive areas, it delivers regulated torque and speed to conveyors, mixers, and filling lines operating in ATEX zones. Power and feedback wiring enter through a terminal box mounted on top of the housing, which simplifies alignment when the motor is fixed to gearboxes or direct-drive shafts.
Its electromagnetic system uses winding code 058 with an inductance of 0.170 mH and a resistance of 2.20 Ω at 20 °C. Continuous operation with a 60 K temperature rise yields 28.0 Nm of stall torque while drawing 28.4 A. Dynamic motion can demand a peak torque of 102.0 Nm and speeds up to 4500 rpm. With a torque constant of 1.15 Nm/A, the controller can convert current commands into mechanical output. A discharge capacitance of 10.3 nF helps limit voltage overshoot at the terminals. Position feedback is supplied by an optical multi-turn absolute Hiperface encoder, model M1, with 128 increments per revolution. The keyed shaft follows DIN 6885 dimensions, and a shaft seal helps block dust or oil from entering the ATEX-compliant housing.
Service limits cover ambient air from 0 to +40 °C. The cast frame weighs 45.0 kg and helps stabilize winding temperature during continuous duty. Acceleration bursts can be supported by a maximum RMS phase current of 127.6 A, used with insulation class 155 (F) and a voltage constant of 70.0 V/1000 rpm. The rotor inertia of 0.01940 kgm² balances responsiveness with load damping. Cable glands accept diameters from 13 mm to 16 mm, and the top-entry layout keeps field wiring clear of obstructions. Operating noise is 61.1 dB(A) ±3 dB. The motor has no holding brake, so external mechanical restraint is required when static torque cannot secure the load.
