Product Description:
The MKE098B-047-KG1-BUNN servo motor is built by Bosch Rexroth Indramat and belongs to the MKE Synchronous Motors series. It is intended for use in potentially explosive areas, allowing it to drive motion axes in chemical, paint, or grain-handling equipment while meeting hazardous-area requirements. The motor carries UL/CSA housing approval and includes a factory-mounted holding brake to secure the load during shutdowns. Power and feedback leads enter through a terminal box on the B-side of the frame, which keeps the cable glands accessible while maintaining the intended IP protection arrangement.
At standstill with a 60 K winding temperature rise, the motor can deliver 12.0 Nm of continuous torque while drawing 9.8 A of continuous current. For rapid acceleration, the drive can command up to 43.5 Nm of peak torque, and the associated phase current can reach 44.3 A RMS. The torque constant of 1.41 Nm/A provides a direct relationship between winding current and produced torque, which helps the control loop calculate current demand accurately from the required mechanical output. These electrical values are useful when selecting a compatible inverter and matching cable capacity to the motor load.
Dynamic response is affected by the rotor moment of inertia of 0.00430 kgm², which supports a balance between quick speed changes and stable running behavior. The motor is intended for ambient temperatures from 0 to +40 °C and can reach a top speed of 4500 rpm when the drive maintains accurate commutation and accounts for the motor's phase inductance. A plain shaft with a DIN 332 DS thread and a shaft seal supports direct coupling to gearboxes while helping prevent oil ingress. Acoustic emissions remain at 61.8 dB[A], and the assembled unit weighs 18.0 kg, which is manageable for installation and handling.
