Product Description:

The MKE047B-144-CG0-RUNN is a synchronous servo motor built by Bosch Rexroth Indramat for the MKE Synchronous Motors series. Specified for potentially explosive areas, the unit provides precise position and speed regulation in material handling, filling, and packaging lines that must prevent ignition sources while operating under closed-loop drive control. It is intended for automated equipment that requires repeatable rotary motion while remaining compatible with accurate servo regulation during continuous production cycles.

Internally, the rotor construction uses 4 pole pairs, which produce a synchronous electrical frequency that the drive amplifier can track with low torque ripple. Position feedback is supplied by an optical multi-turn Hiperface encoder identified as model M1, and its absolute track provides 128 increments per revolution for precise angular positioning during indexing moves. Cabling enters from the right because the connection hardware is arranged on that side, and power as well as signal conductors terminate inside a terminal box that accepts armored cable glands for hazardous-duty routing. The motor also has a plain output shaft with a front centering hole and a DIN 332 DS thread, which allows direct attachment to gear stages or torsionally stiff couplings without extra adapters.

The stator windings use 155 (F) insulation class, which supports the temperature rise associated with enclosed installation spaces. Certification to UL/CSA requirements allows use in Class I or II equipment layouts commonly found in North American plants. Because the motor is supplied without a holding brake, static loads must be restrained externally during power-off intervals. A shaft seal helps limit contaminant entry at the mechanical interface, and the phase coils use a 144 winding pattern that supports balanced electromagnetic performance with acceptable copper loss.
