Product Description:
The MKE047B-144-KG1-BENN belongs to the MKE Synchronous Motors series produced by Bosch Rexroth Indramat. It is a servo motor intended for installation in potentially explosive atmospheres where dependable motion control is required for pumps, mixers, or positioning axes. The motor’s mechanical design, thermal capability, and electrical winding arrangement are selected to maintain repeatable torque in hazardous zones while pairing directly with IndraDrive controllers for closed-loop automation. This type of motor is suited to applications that need controlled acceleration, stable low-speed operation, and reliable motion behavior in areas where ignition protection is essential.
The electrical interface is arranged so that power and feedback cables exit on the B-side, and all terminations are made inside a terminal box that shields the joints from dust and gas ingress. Its housing meets ATEX requirements, providing an ignition-protected enclosure when the motor surface temperature stays within the permitted class limits. A permanent-magnet holding brake is integrated and generates 2.2 Nm of static torque, allowing the load to remain stationary during power loss. Windings insulated to class 155 (F) tolerate winding temperatures up to 155 °C, and a shaft seal limits vapor ingress toward the bearing set to support operation in humid or solvent-rich environments.
The rotor carries 4 pole pairs, giving the drive a moderate electrical frequency for smooth low-speed control without excessive inverter switching rates. Winding code 144 indicates the resistance and inductance values expected by the matching drive, helping the velocity loop respond predictably with low phase lag. A plain shaft is supplied for direct coupling, and a DIN 332 ‘DS’ thread is tapped in the centering hole to accept extraction tools during service. This shaft arrangement supports coupling to gearboxes or belt pulleys while preserving concentric alignment at the drive end.
