Product Description:

The MKE047B-144-CP0-BENN is a servo motor manufactured by Bosch Rexroth Indramat within the MKE Synchronous Motors series. As a servo motor for potentially explosive areas, it is intended to deliver position-controlled torque in process zones where combustible gases or dust may be present. By combining flameproof construction with closed-loop feedback, the unit provides dependable motion for valves, mixers, and conveying axes that must meet hazardous-location regulations.

The electrical interface is arranged so that power and feedback conductors exit on the B-side, and all terminations are collected in a terminal box that simplifies flameproof cable entry. Position data are generated by an optical multi-turn absolute Hiperface encoder identified as model M1; its internal disk resolves rotor movement into 128 discrete counts per revolution for each turn of the multiturn gear. This resolution supports accurate indexing in closed-loop drives. The stator uses winding code 144, a configuration that matches the electrical characteristics expected by compatible drive controllers and corresponds to the motor's base voltage constant.

Mechanical and thermal attributes align with installation in classified zones. The housing complies with the ATEX directive, so enclosure joints and sealing systems help prevent hot internal parts from igniting the surrounding atmosphere. Windings are rated to 155 (F) insulation class, allowing continuous service while internal temperatures remain below the limit for this thermal category. Four internal magnets create 4 pole pairs, giving the controller a predictable electrical frequency for synchronous operation. Output torque is transmitted through a DIN 6885 keyway machined into the shaft, enabling direct coupling to gearboxes or driven shafts without additional adapters.
