Product Description:

The MKE047B-144-CP0-BUNN is a servo motor built by Bosch Rexroth Indramat for the MKE Synchronous Motors series. Classified as a servo motor for potentially explosive areas, it supplies position-controlled rotary power to actuators installed in hazardous zones where flammable gases or dust may be present. By combining explosion-proof construction with closed-loop feedback, the unit supports tooling, mixers, and conveyors inside protected machine areas while maintaining the motion control expected from a synchronous motor.

The motor’s electrical and feedback connections are arranged for direct integration into industrial control systems. Its power and signal conductors exit on the B-side, and all terminations land in a terminal box that simplifies conduit entry and cable routing. The 144 stator winding matches drive amplifiers intended for medium-voltage and medium-current duty, while insulation rated at 155 (F) allows the copper windings to tolerate elevated operating temperatures during overload peaks. Position feedback is provided by an optical encoder with multiturn absolute Hiperface output, and it stores 128 increments per revolution for basic position detection while the drive handles interpolation for finer control.

Torque is produced by a rotor with 4 pole pairs, which supports stable synchronous operation at moderate electrical frequencies. The motor is supplied without a holding brake, so power-off load retention must be provided by an external locking device or other machine hardware. Compliance with UL/CSA housing standards indicates that materials and clearances meet North American electrical requirements for hazardous locations. A shaft seal helps block vapor ingress along the keyed shaft, and the shaft follows DIN 6885 geometry so couplings with a matching keyway can be fitted directly.
