Product Description:

The MKE118B-024-BP0-KE6 is manufactured by Bosch Rexroth Indramat within the MKE Synchronous Motors series. It is a servo motor for potentially explosive areas and uses an ATEX-compliant housing, allowing operation in hazardous zones. Closed-loop torque and speed control are supported by a single-turn optical EnDat 2.1 encoder with model S2 feedback and 2,048 increments. Power and feedback conductors enter through a terminal box on top of the frame, which accepts cable diameters from 17.0 mm to 19.5 mm, while winding code 024 identifies the electrical layout used for this motor.

At a 60 K stator temperature rise, the motor sustains 28.0 Nm of continuous standstill torque while drawing 15.3 A of continuous current. For short dynamic demands, it can deliver 102.0 Nm of torque and accept up to 69.1 A RMS from the drive. Maximum mechanical speed reaches 4000 rpm, giving the axis a wide operating range. The torque constant is 2.12 Nm/A, which provides predictable torque per ampere. The rotor has an inductance of 0.580 mH and a winding resistance of 7.60 Ω at 20 °C, and a discharge capacitance of 10.3 nF helps limit voltage spikes at the inverter. Operation is permitted at ambient temperatures from 0 °C to +40 °C, and F-class insulation provides thermal margin during continuous use.

The back-EMF constant is 130.0 V/min⁻¹, matching drives that supply the required voltage range. Rotor inertia is 0.01940 kg·m², which supports rapid acceleration without excessive overshoot. The motor weighs 45.0 kg without an optional brake, and this unit is supplied without a holding brake, so the load must be secured by external means during power-off conditions. The output shaft uses a keyway machined to DIN 6885 and includes a fitted shaft seal to help block oil ingress. Acoustic emissions are measured at 61.1 dB[A], which helps limit noise in the surrounding machine area.
