Product Description:

The MKE118D-035-DG0-KE6 is a servo motor manufactured by Bosch Rexroth Indramat within the MKE Synchronous Motors series. Designed for motion tasks in potentially explosive industrial zones, the unit provides closed-loop position feedback through an optical multi-turn absolute EnDat 2.1 encoder with model M2 and 2,048 increments. A terminal box on top of the housing accepts power and feedback conductors, and ATEX-compliant construction paired with an IP65 enclosure allows direct mounting on machinery that operates between 0 °C and +40 °C. This arrangement keeps the motor connections contained at the housing instead of using loose flying leads.

At a 60 K winding temperature rise, the motor sustains 48.0 Nm of continuous stall torque while drawing a steady 29.8 A. These values indicate the load the motor can hold continuously without exceeding its thermal limits. For short accelerations or shock loads, the shaft can deliver a peak of 187.0 Nm, and speed extends up to 3000 rpm. A protection rating of IP65 blocks airborne dust and low-pressure water jets, so additional cabinet shielding is not required. The electromagnetic design converts current to torque at a ratio of 1.87 Nm/A, so each ampere commanded by the inverter produces a predictable increase in torque.

Dynamics are governed by a rotor inertia of 0.03620 kgm², enabling reliable stop-start cycling without excessive overshoot when coupled to medium-mass loads. Installation weight is 65.0 kg, which is important for gantry axes or vertical mounts that must support the motor body. During heavy indexing sequences, the winding may momentarily accept up to 134.3 A RMS, so power cables routed through the 17.0 to 19.5 mm cable entry must be sized for that surge. The motor uses a plain shaft with a frontal centering hole, a DIN 332 DS thread, and an integral shaft seal to simplify coupling while maintaining enclosure integrity. The absence of a holding brake requires external holding force when the axis must remain fixed at standstill.
