Product Description:

The MKE045B-144-GP1-KN synchronous motor is part of the MKE Synchronous Motors series manufactured by Bosch Rexroth Indramat. This unit is built for drive systems that operate in hazardous industrial zones where combustible dusts or gases can be present, providing precise torque and speed commands for automated positioning tasks. By integrating into closed-loop servo packs, it converts electrical energy from a compatible drive into controlled rotary motion that can be coordinated with sensors, actuators, and process controllers on assembly lines, packaging equipment, or material-handling stations.

The power and feedback conductors exit on the top of the housing, a layout that simplifies vertical cabinet wiring and keeps the sealing gaskets away from floor debris. All terminations are executed inside a cast-aluminum terminal box, which provides strain relief and allows access to the connections without disturbing the motor enclosure. For load holding or emergency stops, the motor is supplied with a holding brake, allowing the rotor to be locked whenever the drive output is disabled. Mechanical coupling is achieved through a shaft with keyway that matches a DIN 6885 keyway profile, giving positive torque transmission to pulleys or gear sets while helping prevent slippage under intermittent overloads.

Because it is classified as a servo motor for potentially explosive areas, the frame is purged and machined to limit surface temperatures and eliminate ignition sources when paired with approved drives. A dedicated shaft seal isolates the internal bearings from vapor or dust ingress, preserving lubricant life during long duty cycles. The stator uses winding 144, a coil set selected to balance thermal rise with peak torque density for the 45 mm frame size. This motor is suitable for conveyor diverters, dosing pumps, and similar motion axes that must comply with explosion-protection requirements.
