Product Description:

The MKE037B-144-CP0-LUNN is a synchronous servo motor built by Bosch Rexroth Indramat as part of the MKE Synchronous Motors series. Classified as a servo motor for potentially explosive areas, it is intended for drive tasks in hazardous zones where ignition sources must be minimized. In automated machinery, the unit converts drive-controller commands into precise rotation, supporting closed-loop positioning or speed regulation for conveyors, filling lines, and packaging axes that run in chemical or solvent-laden environments. Its operating concept is suited to applications that require controlled motion while maintaining compatibility with equipment used in regulated industrial areas.

To withstand demanding plant conditions, the housing carries an ingress rating of IP 65, which seals the frame against dust and low-pressure water jets. The insulation system is rated at 155 (F), permitting the windings to operate safely at elevated temperatures during normal service. The allowed ambient range of 0...+40 °C matches common indoor industrial conditions and supports stable operation in standard production spaces. Position feedback is generated by an optical multiturn encoder that reports 128 increments per revolution, enabling the drive to track shaft motion accurately and maintain repeatable axis movement during speed changes and positioning tasks.

The motor is wired through a terminal box that sits on the left side of the stator, which can simplify conduit routing when multiple axes are installed side by side. Compliance with UL/CSA construction standards supports use in North American explosion-risk facilities. Torque is transmitted by a shaft machined with a DIN 6885 keyway, and a shaft seal helps limit vapor ingress along the journal. Because the motor is supplied without a holding brake, external holding force is required when power is removed. The motor uses the 144 winding, allowing the paired drive to apply the proper voltage and current profile for the intended operating range.
