Product Description:

The MKE118B-024-AP0-KE4 servo motor is manufactured by Bosch Rexroth Indramat as part of the MKE Synchronous Motors series. Designed for hazardous-location automation, it uses an ATEX-compliant housing and serves drive axes that must maintain precise torque in paint booths, mixers, and filling stations where flammable vapors may be present. The model is delivered without a holding brake and uses a top-mounted terminal box for power and feedback conductors. This arrangement suits installations where cables are routed upward, and it keeps electrical terminations concentrated at the top of the housing for orderly machine integration.

At standstill and with a 60 K winding rise, the motor can supply 28.0 Nm of continuous torque while drawing 15.3 A of RMS current. These values correspond to the 024 winding, which has an inductance of 0.580 mH and a resistance of 7.60 Ω at 20 °C. When brief overloads occur, the drive may command up to 69.1 A to produce 102.0 Nm of shaft torque before thermal limits intervene. A torque constant of 2.12 Nm/A relates current to output torque, and the 10.3 nF discharge capacitance helps protect encoder signals from common-mode noise. Class 155(F) insulation supports the associated thermal load, and the sound pressure level remains 61.1 dB(A) ± 3 dB during rated duty.

The motor reaches a maximum speed of 4000 min⁻¹ and has a rotor inertia of 0.01940 kgm², which supports controlled acceleration when 128-increment S1 optical single-turn Hiperface feedback is active. Installation uses a 13.0 to 16.0 mm cable entry with a top connection direction, and the shaft is sealed and fitted with a DIN 6885 keyway for coupling to driven equipment. Operation is permitted from 0 to +40 °C, and the unit mass of 45.0 kg supports stable mounting on vertical or horizontal axes. A voltage constant of 130.0 V/min⁻¹ matches inverter output characteristics, and the shaft seal helps preserve IP protection in washdown environments.
