Product Description:

The MKE118B-024-DP0-KUN is a three-phase servo motor produced by Bosch Rexroth Indramat for the MKE Synchronous Motors series. It is intended for use in potentially explosive areas, where regulated torque and speed are needed in chemical, paint, or grain-processing equipment and where ignition sources must be carefully controlled. Integrated feedback, thermal monitoring, and ATEX-oriented construction allow the motor to work with compatible drive controllers in hazardous industrial environments.

The motor provides a continuous standstill torque of 28.0 Nm when the shaft is held at zero speed under rated thermal conditions. It requires 15.3 A of continuous current to produce that torque, which helps keep amplifier sizing moderate. During acceleration, the shaft can deliver up to 102.0 Nm for short intervals. Maximum speed is 4000 rpm, allowing the motor to support both positioning and higher-speed servo duty. A torque constant of 2.12 Nm/A allows the drive to translate torque demand into current with predictable response. Rotor inertia is 0.01940 kg·m², and the winding has 0.580 mH inductance with 7.60 Ω resistance. Position data are supplied by an optical multiturn EnDat 2.1 encoder with 2,048 increments per revolution, and power and feedback leads exit through a top-mounted terminal box.

Operation is permitted in ambient temperatures from 0 to +40 °C, and the Class 155 F insulation system withstands the internal heat produced during normal loading. The back-EMF constant is 130.0 V/min⁻¹, which gives predictable regenerative behavior during deceleration. The motor weighs 45.0 kg and uses a shaft seal together with a shaft that has a DIN 6885 keyway for secure coupling. Acoustic emission remains below 61.1 dB[A], which helps limit operating noise in enclosed equipment. Additional characteristics include a 10.3 nF discharge capacity, winding code 024, compliance with UL and CSA requirements for North American hazardous locations, and delivery without a holding brake.
