Product Description:

The MKE118D-035-NG0-KUN is a synchronous servo motor produced by Bosch Rexroth Indramat within the MKE Synchronous Motors series. As a servo motor for potentially explosive areas, it provides precise torque and speed regulation to automated equipment operating in hazardous zones. The unit uses a plain shaft with a front centering hole and a top-mounted terminal box for power and feedback leads, and it meets UL/CSA housing standards for industrial safety.

During continuous duty with a 60 K winding temperature rise, the motor supplies 48.0 Nm of standstill torque while drawing 29.8 A. The enclosure is rated IP 65, and a shaft seal helps keep out dust and water jets. Winding code 035 uses a resistance of 0.210 Ω at 20 °C and an inductance of 3.20 mH, while insulation class 155 (F) supports long-term thermal endurance. Connections exit from the top of the frame for simpler cable routing, and ambient operation is limited to 0 to +40 °C. The motor does not include a holding brake, so static loads must be secured by external means. It can reach speeds up to 3000 rpm, and a discharge capacity of 20.2 nF helps protect the winding system from transient energy. For short-term overloads, the stator can withstand 134.3 A RMS without exceeding thermal limits.

Dynamic operation is supported by a maximum torque of 187.0 Nm and a rotor moment of inertia of 0.03620 kg·m², which helps balance acceleration with current demand. Acoustic emissions remain near 61.1 dB[A], and the torque constant of 1.87 Nm/A allows predictable drive response. With a mass of 65.0 kg, the motor can be integrated onto vertical axes without especially heavy counterweights. The voltage constant of 114.5 V/1000 rpm supports regenerative voltage calculations, and a DIN 332 DS shaft thread simplifies attachment of alignment tools during installation.
