Product Description:

The MKE118B-024-CG0-KE4 is a servo motor manufactured by Bosch Rexroth Indramat for the MKE Synchronous Motors series. Classified for potentially explosive areas, it provides electrically commutated torque to actuators and positioning axes in paint shops, chemical mixers, and other automation cells where flammable vapors may be present. An ATEX housing, the lack of a holding brake, a plain shaft with a frontal centering hole, and a top-mounted terminal box connection allow safe integration into zone-rated equipment during installation.

The motor produces 28.0 Nm of continuous standstill torque at a 60 K winding rise, supported by 15.3 A of continuous current from the drive. A torque constant of 2.12 Nm/A lets the controller estimate load response directly from stator current. For short overloads, the electromagnetic system reaches 102.0 Nm, and rotational speed remains regulated up to 4000 rpm before the 130 V/1000 rpm voltage constant reaches inverter limits. Winding code 024 uses 7.60 Ω of resistance and 0.580 mH of inductance, and insulation class 155 (F) withstands the thermal stress of repeated production cycles.

Transient commands may draw 69.1 A, so supply cables and protection devices must be sized for that RMS value. Motion smoothness is aided by a rotor inertia of 0.01940 kg·m², while the overall unit mass of 45.0 kg adds damping at the machine interface. The approved ambient range of 0 to +40 °C matches standard control cabinet conditions, and a shaft seal helps limit contaminant ingress. A DIN 332 DS thread supports coupling, and cable glands sized 13 to 16 mm route power and the optical multi-turn Hiperface encoder signal from model M1 with 128 increments. Discharge capacity is 10.3 nF for EMC behavior, and the housing has a sound pressure level of 61.1 dB(A) in enclosed machinery.
