Product Description:

The MKE035B-144-GG0-KN is a compact synchronous servo motor built by Bosch Rexroth Indramat for the MKE Synchronous Motors series. It serves as a rotary drive element that converts electrical power from an inverter into controllable torque for positioning or velocity regulation on automated machinery installed in hazardous production zones. Applications include valve actuation, agitators, and conveyor modules where a flameproof housing and precise closed-loop motion are both required. Integrated temperature sensors relay winding data to the drive so current can be reduced before critical limits are reached.

The motor’s power and feedback terminals are oriented upward because it uses a top connection direction. All conductors land in a rugged terminal box, enabling armored cable entry while keeping the winding space sealed from dust. The electromagnetic assembly uses winding code 144, which matches the resistance and inductance values expected by compatible Indramat drives. For mechanical attachment of couplings or pulleys, the shaft tip carries a DIN 332 'DS' thread, so tooling can be drawn into the centering bore without side loading. A positive-contact shaft seal is fitted to block oil or vapor from reaching the internal stator laminations during service.

Output torque is transferred through a plain shaft, so no keyway stress concentrations exist and torque is transmitted solely by frictional clamping. Precision location of the motor relative to load components is simplified by the frontal centering hole, which provides a repeatable datum during alignment. In dynamic stop scenarios, the rotor must be held by the drive because the unit ships without a holding brake, which reduces mass and simplifies maintenance in vertical mounting positions. The entire assembly is rated as a servo motor for potentially explosive areas, meaning its surface temperatures and construction materials comply with ignition protection requirements for designated gas or dust atmospheres.
