Product Description:

The MKE047B-144-KG0-AUNN is a servo motor produced by Bosch Rexroth Indramat within the MKE Synchronous Motors series. Designed for use in potentially explosive areas, the unit converts electrical energy from a matched drive amplifier into controlled mechanical rotation for process automation, conveyors, and axis-handling tasks. Its series-specific safety design helps motion systems in hazardous zones maintain accurate speed and torque control without creating unintended ignition sources. It is intended for synchronized servo applications where repeatable motion must be maintained under the protective constraints of explosion-protected equipment.

This motor routes its power and feedback conductors through an A-side entry into a cast-aluminum terminal box, a layout that simplifies wiring inside flameproof housings used in zone-rated cabinets. The stator uses winding code 144 to match the electrical characteristics of the MKE drive family, and its copper is insulated to the 155 (F) thermal class for continuous operation at elevated temperatures without reducing varnish life. Because the motor operates without a holding brake, any static positioning after power is removed must be provided by drive torque or a separate mechanical locking device. The enclosed connection area also keeps power and feedback terminations organized within the motor housing.

For installations subject to North American safety inspections, the housing meets UL/CSA construction requirements. The rotor has 4 permanent-magnet pole pairs, which support precise synchronous commutation and stable low-speed control. Torque is transmitted through a plain shaft fitted with a DIN 332 compliant DS thread at the front for puller tools, and a front centering hole helps align couplings during assembly. A dedicated shaft seal helps block lubricant migration and supports the specified IP protection by separating the motor interior from surrounding contaminants during operation.
