Product Description:

The MKE045B-144-KP0-KN is a synchronous servo motor produced by Bosch Rexroth Indramat within the MKE Synchronous Motors series. Designed as a motion source for hazardous industrial zones, the unit converts electrical energy into controlled rotary movement for automation tasks that must comply with explosion-protection requirements. It fills the role of a compact drive element that pairs with drive controllers to position machine axes where flammable gases or dusts may be present. Its synchronous design supports precise speed and position control in automated systems installed in protected process areas.

The motor housing carries its electrical interface on the top, so power and feedback cables exit upward and can be routed along machine frameworks without sharp bends. Connections are completed through a terminal box, allowing armored cable glands and screw terminals to be fitted on site for secure clamping in vibration-exposed assemblies. For stopping and holding functions, the unit ships without a holding brake, so external mechanical locks or closed-loop torque control must maintain position once the drive is de-energized. Because it is a servo motor for potentially explosive areas, the stator insulation, surface temperature limits, and grounding provisions follow ignition-protection directives. Torque is transferred through a shaft with a keyway, giving positive mechanical engagement with couplings or pulleys while resisting slip under peak load.

The shaft end is machined to a DIN 6885 keyway, so standard keys can be selected without custom tooling when integrating gearboxes or timing elements. This arrangement supports the use of common coupling components in industrial motion systems. There is a shaft seal between the motor face and the rotating shaft to limit the ingress of process dust and retain bearing grease during long duty cycles. The winding 144 matches the current, voltage, and resolver parameters recommended by Bosch Rexroth Indramat for compatible drives.
