Product Description:
The MKE118B-024-NP0-KE4 is a servo motor built by Bosch Rexroth Indramat and belongs to the MKE Synchronous Motors series. It is intended for potentially explosive areas where ignition sources must be minimized during operation. The motor still provides closed-loop speed and torque control for positioning tasks in industrial automation.
At standstill, the motor can supply 28.0 Nm of continuous torque while drawing 15.3 A, giving a steady load capability for holding or low-speed processes. Dynamic motion is supported by a peak torque of 102.0 Nm and a peak phase current of 69.1 A RMS. A top speed of 4000 rpm suits high-speed axes, and the 024 winding pairs these ratings with 0.580 mH of inductance and 7.60 Ω of resistance for predictable drive tuning. Power enters through a terminal box positioned on top of the housing, and its cable entry accepts diameters from 13.0 mm to 16.0 mm to simplify armored conduit routing. The shaft uses a keyway in accordance with DIN 6885, and the housing follows ATEX requirements for installation in zone-rated machine frames. Because the design is supplied without a holding brake, mechanical locking or drive torque must be used for long-term position retention.
A rotor inertia of 0.01940 kg·m² balances responsive acceleration with smooth settling, and operation is permitted in an ambient range of 0 to +40 °C under normal plant conditions. The electromagnetic system delivers a torque constant of 2.12 Nm/A, while the back EMF constant is 130 V per 1000 rpm and the discharge capacitance is 10.3 nF to help suppress common-mode noise. The motor weighs 45.0 kg without the optional brake, includes a shaft seal to limit oil ingress, and has insulation class 155 F for thermal endurance. Sound pressure reaches 61.1 dB(A), which remains within typical factory limits.
