Product Description:

The MKE047B-144-CP0-LUNN is a servo motor produced by Bosch Rexroth Indramat for the MKE Synchronous Motors series. Designed for potentially explosive areas, it delivers precise rotary motion in automation zones where ignition risks must be controlled. The motor uses an M1 optical multi-turn absolute Hiperface encoder to provide position feedback to the drive controller. Its housing, shaft, and connection layout are tailored for integration in end-of-line packaging, mixing, or material-handling stations that demand consistent torque and closed-loop positioning. This arrangement supports accurate positioning in applications that require repeatable starts, stops, and speed changes.

The stator winding is coded as 144, which indicates the electrical resistance, inductance, and thermal profile for this frame size. Power and feedback conductors exit on the left side, and they are routed through a terminal box that accepts threaded cable glands for secure strain relief. Rotor geometry incorporates 4 pole pairs, allowing smooth torque generation at low speeds while maintaining magnetic symmetry. The integrated optical encoder delivers 128 increments per revolution, and when combined with the multi-turn track of the Hiperface interface, it enables fine position control over extended travel ranges. Encoder model M1 supplies this information without additional adapters.

Thermal endurance is classified at 155 (F), meaning the winding insulation tolerates continuous operation up to 155 °C before degradation. Compliance with UL/CSA construction rules simplifies acceptance on North American hazardous-location panels. The motor is supplied without a holding brake, so external mechanical restraints or drive torque must secure the load during power-off states. A shaft with keyway machined to DIN 6885 transmits torque to couplings, and a positive shaft seal keeps process dust or vapors away from the bearing set.
