Product Description:
The MKE047B-144-KP1-BUNN servo motor is produced by Bosch Rexroth Indramat within the MKE Synchronous Motors series. Intended for motion axes situated in hazardous or potentially explosive zones, this unit supplies controlled torque and position feedback for conveyors, mixers, or indexing tables in process plants. As a servo motor configured for such environments, it combines flameproof construction with precise speed regulation so it can be paired with Rexroth drive controllers without relocating sensitive mechanics outside the classified area.
Power and feedback conductors exit on the B-side, letting control-cabinet layouts keep cable loops short. Terminations are completed inside a sealed terminal box that maintains shielding and ingress protection. The stator carries winding code 144, which corresponds to electrical values used by the drive family. The rotor contains 4 magnetic pole pairs to establish synchronous electrical cycles. For dynamic holding, a spring-applied brake delivers 2.2 Nm of static torque and engages automatically when power is removed. Class F insulation supports continuous winding temperatures up to 155 (F), allowing cyclic duty without degrading the varnish system.
The enclosure meets UL/CSA construction standards, permitting installation on North American machinery that must satisfy third-party safety listings. A positively fitted shaft with keyway transfers torque to couplings, and the interface follows the precision profile of DIN 6885 Keyway to minimize backlash. A shaft seal is provided to limit vapor migration toward the bearings, which is important when the motor operates in washdown or solvent-laden zones. Because the unit is approved for potentially explosive areas, it can be mounted close to process vessels to shorten mechanical linkages and improve response.
