Product Description:

The MKE118B-024-AP0-KE0 is a synchronous servo motor built by Bosch Rexroth Indramat for the MKE Synchronous Motors series. It is intended for potentially explosive areas and carries an ATEX-compliant housing, allowing direct integration into hazardous-zone drives that need precise speed and torque control. A terminal box mounted on the top of the frame routes power and feedback wiring, while the unit’s shaft with a DIN 6885 keyway supports common couplings in pump, agitator, and conveyor mechanisms and keeps connections above the motor housing.

The motor’s winding code 024 works with a resistance of 7.60 Ω and an inductance of 0.580 mH, which shape its electrical response. At standstill the stator can deliver 28.0 Nm with a continuous current of 15.3 A. Drive controllers can momentarily command up to 69.1 A to reach a peak torque of 102.0 Nm. Mechanical output is capped at 4000 rpm, matched to a 2.12 Nm/A torque constant and a voltage constant of 130 V per 1000 rpm. Position feedback is supplied by an optical single-turn Hiperface encoder, model S1, providing 128 increments for closed-loop regulation. All cabling exits upward through the top terminal box, and the discharge capacity is 10.3 nF for controlled common-mode currents. A shaft seal is fitted, but the motor is supplied without a holding brake, so static load retention must be handled by external mechanics or drive torque.

Thermal limits are set for ambient temperatures from 0 to +40 °C, and insulation class 155 (F) permits winding temperatures up to 155 °C under those conditions. The laminated rotor stores kinetic energy with a moment of 0.01940 kgm², yet installation mass remains 45.0 kg, easing alignment on steel baseplates. Sound emission is 61.1 ±3 dB(A), which supports use in nearby work areas. The 10.3 nF discharge path and the ATEX housing reduce ignition risk in hazardous locations, and the voltage constant helps match the associated inverter to the motor.
