Product Description:

The MKE098B-047-BP0-AUNN is a servo motor manufactured by Bosch Rexroth Indramat for the MKE Synchronous Motors series. It is intended for use in potentially explosive areas where precise torque and speed control are required. The motor housing complies with UL and CSA requirements, and the terminal box on the A-side helps simplify wiring. The drive end uses a shaft with a DIN 6885 keyway, and a shaft seal helps limit dust or oil migration. Because the unit is supplied without a holding brake, applications that require static position retention must rely on external locking or drive torque.

The motor can operate in ambient temperatures from 0 to +40 °C. At a 60 K winding temperature rise, it produces 12.0 Nm of continuous standstill torque while drawing 9.8 A of armature current. A single-turn optical EnDat 2.1 encoder provides position feedback with 2,048 increments per revolution, and a capacitance of 6.7 nF supports EMC performance in long-cable installations. Peak speed reaches 4500 rpm, supported by a low winding inductance of 1.20 mH and a voltage constant of 91.0 V per 1000 rpm. The F-class insulation system supports elevated internal temperatures, and a winding resistance of 8.400 Ω is associated with copper losses during continuous duty. Thermal noise is limited to 61.8 dB[A] at one meter. With an electrical torque constant of 1.41 Nm/A, the motor can be matched to inverters rated for the 44.3 A RMS ceiling.

The overload region allows a mechanical output of 43.5 Nm maximum torque, which covers rapid indexing or short-term shock loads before the motor reaches the 155 °C insulation limit. The moment of inertia is 0.00430 kg·m², which supports a balance between quick acceleration and stable operation. Total weight is 18.0 kg, making the frame suitable for vertical-axis mounting. Winding code 047 matches the resistance, inductance, and maximum current values used by the drive amplifier.
