Product Description:
The MKE118B-024-DP0-KE4 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MKE Synchronous Motors series. Classified as a servo motor for potentially explosive areas, it is intended for torque-controlled motion tasks in process lines that require ignition protection. The unit weighs 45.0 kg and uses winding code 024. Its insulation class 155 (F) supports the stated thermal limits during operation.
Under a stator temperature rise of 60 K, the motor can deliver a continuous standstill torque of 28.0 Nm with a continuous current draw of 15.3 A. The motor has a torque constant of 2.12 Nm/A, with a phase inductance of 0.580 mH and a phase resistance of 7.60 Ω. When acceleration reserve is required, the drive may command up to 69.1 A, allowing the rotor to reach a peak torque of 102.0 Nm. Together with a rotor moment of inertia of 0.01940 kg·m², this supports fast indexing at speeds up to 4000 rpm without excessive overshoot. A voltage constant of 130.0 V per 1000 rpm and a discharge capacity of 10.3 nF assist the inverter in controlling voltage gradients and common-mode currents.
The housing can be operated in ambient temperatures from 0 to +40 °C and satisfies the ignition protection requirements of ATEX. A terminal box mounted on the top of the frame routes the power, brake, and encoder cables upward, and its glands accept cables from 13.0 mm to 16.0 mm in diameter. Position feedback comes from an optical multi-turn absolute EnDat 2.1 encoder, model M2, that provides 2,048 increments per revolution for precise closed-loop control. The motor has a keyed shaft in accordance with DIN 6885, and a shaft seal is fitted to limit ingress. The motor produces a sound pressure level of 61.1 dB(A) ±3 during rated operation and is supplied without a holding brake, so external locking devices must secure vertical axes when de-energized.
