Product Description:

The MKE118B-024-CG0-UUN is a servo motor for potentially explosive areas produced by Bosch Rexroth Indramat within the MKE Synchronous Motors series. A terminal box mounted on the bottom of the housing provides cable entry, and the plain shaft with a frontal centering hole simplifies coupling to driven equipment. The enclosure follows UL/CSA requirements and carries a shaft seal, so it can be installed in process zones that require limited dust or fluid ingress while still meeting hazardous-location demands for automated valves, mixers, or conveyor sections.

At a 60 K winding temperature, the motor supplies a continuous stall torque of 28.0 Nm, allowing machinery to hold load without overheating. Generating that torque requires a continuous standstill current of 15.3 A, a value that guides drive controller sizing for steady positioning tasks. Its torque constant of 2.12 Nm/A links each ampere of phase current to delivered torque, supporting accurate closed-loop regulation at low speed. The winding inductance is 0.580 mH; this comparatively low inductance lets current rise quickly, which shortens response time when the control system issues a step change in torque command.

When accelerated beyond stall, the motor can reach a peak torque of 102.0 Nm and a mechanical speed of up to 4000 rpm; these limits set the dynamic range for rapid indexing cycles. Transient events such as start-up or shock loading may draw up to 69.1 A RMS, so the power stage must tolerate that surge. Rotational dynamics are influenced by a rotor moment of inertia of 0.01940 kgm², which provides moderate flywheel effect without slowing control response. The assembly weighs 45.0 kg, and its thermal design supports continuous duty in ambient temperatures from 0 °C to +40 °C when airflow around the frame is unobstructed.
