Product Description:

The MKE098B-047-PP0-BENN is a three-phase servo motor manufactured by Bosch Rexroth Indramat for the MKE Synchronous Motors series. As a servo motor intended for potentially explosive areas, it provides motion control inside ATEX-classified zones where flammable gases or dust may be present. Within an automation cell, the unit couples directly to drives so that controlled torque and speed can be delivered to pumps, mixers, or positioning modules while maintaining safe surface temperatures.

The motor delivers 12.0 Nm of continuous standstill torque at a 60 K winding temperature rise while drawing 9.8 A. These values describe the continuous thermal load permitted by the Class 155 F insulation system at ambient temperatures from 0 to +40 °C. A terminal box on the B-side routes power and feedback conductors for straightforward cable entry. Speed is adjustable up to 4500 rpm, and the winding has an inductance of 1.20 mH and a phase resistance of 8.400 ohms. The motor uses winding code 047 and has a discharge capacity of 6.7 nF to help suppress high-frequency disturbances from pulse-width-modulated drives. Because the motor is supplied without a holding brake, any required static position retention must be provided externally.

For short-term overloads, the motor can deliver up to 43.5 Nm of torque and accept 44.3 A RMS without demagnetization. Dynamic response benefits from a rotor moment of inertia of 0.00430 kg·m², which supports rapid acceleration while limiting current peaks. The motor weighs 18.0 kg without the optional brake and includes a shaft seal to limit the ingress of process fluids. A shaft with a DIN 6885 keyway transfers power to the driven load. Sound pressure reaches 61.8 dB(A) ±3 under nominal conditions, and the torque constant of 1.41 Nm/A is paired with a voltage constant of 91.0 V per 1000 rpm.
