Product Description:
The MKE118D-027-NP0-KE4 is a Bosch Rexroth Indramat servo motor in the MKE Synchronous Motors series. Designed for potentially explosive environments, it pairs flame-proof construction with an ATEX-certified housing so it can be installed in zone-rated machinery without additional enclosures. The unit supplies rotary motion to conveyors, mixers, and similar equipment where precise speed control is required in ambient temperatures from 0 to +40 °C.
At standstill, the motor can deliver 48.0 Nm of continuous torque while drawing 22.1 A; this rating is based on a 60 K winding temperature rise and supports slow, load-holding operation. For short-duty peaks, the drive permits a maximum RMS current of 99.6 A and accelerates up to 3000 rpm, enabling rapid cycle changes. An enclosure rating of IP 65 blocks dust ingress and low-pressure water jets, and the ATEX housing helps prevent internal sparks from igniting external gases. Electrical termination is through a terminal box mounted on the top of the frame, so power and feedback cables exit upward, and the cable gland accepts diameters from 13.0 to 16.0 mm. Internally, winding code 027 has 0.350 Ω of resistance and 5.70 mH of inductance at 20 °C, while discharge capacitance is 20.2 nF for EMC filtering. F-class insulation allows a winding temperature of 155 °C, and a sound pressure level of 61.1 dB(A) keeps acoustic output moderate.
The motor’s dynamic envelope includes a peak torque of 187.0 Nm, a torque constant of 2.52 Nm/A, and a back-EMF constant of 154.5 V per 1000 rpm, which together indicate its voltage demand during acceleration. Rotor inertia is 0.03620 kg·m², balancing quick speed changes with stable control, and the keyed shaft complies with DIN 6885 for positive mechanical locking. The motor has a shaft seal and no holding brake, so external measures must secure vertical axes when power is removed. Overall mass is 65.0 kg, providing thermal capacity and vibration damping for heavy-duty service.
