Product Description:

The MKE118B-024-DG1-UUN is a servo motor manufactured by Bosch Rexroth Indramat within the MKE Synchronous Motors series. Classified for use in potentially explosive areas, this motor attaches to certified drives to perform precise speed and position control in automated mixers, filling stations, and material-handling zones. Its explosion-protected construction and optical multi-turn feedback allow integration where reliable motion must coexist with hazardous atmospheres.

At standstill, the motor can supply 28.0 Nm of continuous torque while drawing 15.3 A, values that reflect the 024 winding and a 60 K temperature rise. A torque constant of 2.12 Nm/A relates current to shaft torque, and the maximum permissible RMS phase current is 69.1 A for short accelerations. The generated back EMF reaches 130.0 V/min⁻¹, so the bus voltage must be selected accordingly. The motor has a phase inductivity of 0.580 mH, a phase resistance of 7.60 Ω, and a discharge capacity of 10.3 nF that helps limit bearing currents. Class 155 F insulation handles the thermal load, and safe operation is permitted from 0 °C to +40 °C ambient. The UL/CSA-compliant housing keeps sound pressure to 61.1 dB(A), and power is routed through a terminal box mounted on the bottom of the frame.

Peak torque reaches 102.0 Nm and can be delivered up to 4000 min⁻¹; combined with a rotor inertia of 0.01940 kg·m², this supports high acceleration without instability. Position data come from an M2 optical multi-turn EnDat 2.1 encoder that provides 2,048 increments per revolution. A holding brake supplies 32 Nm for safe stops, and a shaft seal protects the plain shaft, which has a frontal centering hole and a DIN 332 DS thread. The motor weighs 45.0 kg without the brake, and all power and feedback conductors exit downward through the bottom-facing terminal box.
