Product Description:

The MKE118B-024-PG0-KE4 is a servo motor manufactured by Bosch Rexroth Indramat for the MKE Synchronous Motors series. It is intended for use in potentially explosive areas and conforms to ATEX housing standards, making it suitable for drive tasks where gaseous or dusty atmospheres may be present. In automated production cells, the unit converts drive controller current into mechanical rotation while supporting coordinated motion on packaging, filling, and material-handling equipment. Its configuration is suited to installations that require controlled servo performance without using a standard-purpose motor housing.

At a 60 K winding temperature rise, the motor delivers a continuous shaft torque of 28.0 Nm from a steady-state current of 15.3 A. For dynamic moves, the stator can handle up to 69.1 A RMS, enabling peak torque of 102.0 Nm. Maximum mechanical speed reaches 4000 rpm, giving a broad operating range for fast positioning tasks. Thermal capacity is supported by Class 155 (F) insulation and an allowable ambient temperature from 0 to +40 °C. The three-phase stator uses winding code 024 with 0.580 mH of inductance and 7.60 Ω of resistance at 20 °C, which helps the drive regulate current accurately. Housing sound pressure is 61.1 dB[A] ±3, and the discharge capacitance between windings and frame is 10.3 nF.

The torque constant is 2.12 Nm/A, and the back-EMF constant is 130.0 V/min⁻¹ for controller calculations related to motor behavior. With a rotor inertia of 0.01940 kg·m² and a bare weight of 45.0 kg, the motor suits larger axes that need stable motion as well as reasonable acceleration response. It is built without a holding brake, so position retention must be supplied by external hardware or by drive torque. The plain shaft has a frontal centering hole, a DIN 332 DS thread, and a shaft seal. Power leads exit through a terminal box on the top of the housing, and cable glands from 13 mm to 16 mm are supported.
