Product Description:
The MKE118D-012-BG0-KUN is a servo motor manufactured by Bosch Rexroth Indramat and assigned to the MKE Synchronous Motors series. It is intended for motion axes that operate in potentially explosive areas and provides closed-loop speed and position control for conveyor sections, mixers, or filling stations that must meet UL and CSA housing requirements. Electrical power and feedback conductors enter from the top through a terminal box, which helps simplify vertical cabinet wiring. The unit is supplied without a holding brake, so the load must be secured by external locking or continuous drive torque when power is removed.
The motor can deliver a standstill torque of 48.0 Nm while drawing a continuous standstill current of 13.0 A. This combination indicates the sustained load it can support without exceeding a 60 K temperature rise. A rotor moment of inertia of 0.03620 kgm² moderates acceleration and supports stable regulation when the motor is coupled to large gear ratios. For brief overloads or fast indexing moves, the shaft can reach a peak torque of 187.0 Nm, and the power electronics may supply up to 58.5 A RMS to reach that limit.
The three-phase stator winding has an inductance of 15.000 mH and a torque constant of 4.29 Nm/A, which influence current ripple and controller response. An enclosure rating of IP 65 blocks dust ingress and low-pressure water jets, which is useful in washdown areas. The bare motor mass is 65.0 kg, so the mounting structure must support that weight along with process loads. The motor is rated for ambient temperatures from 0 to +40 °C and uses an optical single-turn EnDat 2.1 encoder with 2,048 increments for feedback. It also has a shaft seal, a plain shaft with a DIN 332 "DS" thread, and a measured sound pressure level of 61.1 dB(A).
