Product Description:

The MKE047B-144-GP0-BENN is a synchronous servo motor produced by Bosch Rexroth Indramat in the MKE Synchronous Motors series. Classified as a servo motor for potentially explosive areas, it is designed to deliver precise torque and speed control on machinery that operates inside hazardous gas or dust zones. By pairing with a compatible inverter, the motor drives positioning or process axes in chemical, pharmaceutical, or bulk-material installations where ignition-safe motion is required.

The power and feedback conductors are routed toward the equipment because the connections are on the B-side of the housing. A cast-metal terminal box forms the interface so field wiring can be clamped under screw terminals rather than fitted with molded connectors. The motor is supplied without a holding brake, meaning load retention during power-off conditions must be handled by external mechanisms or drive torque. Its enclosure follows ATEX requirements, allowing installation in explosive atmospheres without additional protective housings. Windings are insulated to class 155 (F), so the stator can tolerate operating temperatures up to 155 °C without insulation breakdown.

The electromagnetic design includes 4 pole pairs, so the electrical frequency seen by the stator is four times the mechanical output speed and supports fine torque ripple control at low rpm. Mechanical coupling is provided through a shaft with a keyway, which ensures positive torque transmission to standard hubs. The key follows DIN 6885 Keyway geometry, simplifying alignment with metric drive components. A shaft seal is fitted to limit dust or liquid ingress along the journal, an important feature in washdown or dusty production zones. Stator configuration code 144 identifies the coil resistance and inductance used for current control in this frame size.
