Product Description:
The MKE118B-024-AG0-KI4 is a servo motor for potentially explosive areas produced by Bosch Rexroth Indramat within the MKE Synchronous Motors series. It converts electrical energy into controlled rotation for conveyors, mixers, or positioning axes installed in hazardous zones. Winding code 024 identifies the electrical layout, and an optical, single-turn Hiperface encoder model S1 returns 128 increments per revolution to the drive for closed-loop speed and position control. A plain shaft with a shaft seal supports couplings without additional keys and aligns through the front centering hole. The unit is supplied without a holding brake, so static loads must be managed by external devices.
The motor draws a continuous standstill current of 15.3 A and produces a continuous standstill torque of 28.0 Nm at a 60 K winding temperature rise. Its maximum speed is 4000 rpm, and the electrical characteristics include 0.580 mH phase inductance and 7.60 Ω resistance for responsive current behavior. With a torque constant of 2.12 Nm/A, the controller can estimate output torque accurately, while rotor inertia of 0.01940 kgm² affects acceleration response. The drive also uses a voltage constant of 130 V per 1000 rpm to calculate back EMF. Power and feedback lines enter a top-mounted terminal box through 13.0 to 16.0 mm cable glands, and the 10.3 nF discharge capacitance helps limit common-mode noise. A DIN 332 DS thread in the shaft end supports puller tool attachment, and the sound pressure level is 61.1 dB[A] ± 3 at nominal output. Insulation class 155 (F) is used for the thermal load associated with operation.
For short load peaks, the drive can accept 69.1 A RMS and deliver 102.0 Nm before current limiting intervenes. The motor mass of 45.0 kg slows internal temperature rise during changing load conditions. Safe use is specified between 0 to +40 °C. These limits affect inverter sizing, mounting, and enclosure ventilation during repeated start-up cycles.
