Product Description:
The MKE035B-144-KP1-KN is a synchronous servo motor built by Bosch Rexroth Indramat for the MKE Synchronous Motors series. It is intended for closed-loop position and speed control on rotary axes located in hazardous zones where electrical equipment must contain any ignition source. By combining explosion-proof construction with precise torque regulation, the motor allows machine builders to drive mixers, filling stations, and painting robots in hazardous production cells without replacing electric actuation with pneumatic or hydraulic alternatives. This makes the motor suitable for controlled electric motion in areas that require ignition-protected equipment.
The electrical terminations follow the specified connection direction, with all power and feedback conductors exiting at the top, which simplifies cabinet routing when the unit is mounted vertically. A cast-metal terminal box replaces molded connectors so threaded conduit hubs can be installed to meet zone-rated wiring practices. Classified as a servo motor for potentially explosive areas, the enclosure and cable glands are suitable for flammable gas or dust atmospheres and keep surface temperatures within the permitted T-class. Internally, the stator uses the factory-assigned 144 winding code, which establishes resistance and inductance values compatible with MKE drive controllers and sets the motor’s torque constant over the full operating speed range.
The specified shaft design supports direct coupling to gearheads or pulleys without auxiliary sleeves. A hardened shaft with a keyway uses the standardized DIN 6885 keyway profile, so metric keys seat flush and distribute torque evenly across the hub. A positive-contact shaft seal sits between the bearing journal and the exterior to block process vapors and fine dust from entering the housing, which helps protect both lubricant and winding insulation. This layout allows torque transfer through standard hubs while reducing the chance of contamination reaching internal bearing grease.
