Product Description:
The MKE098B-047-NG0-AUNN is a servo motor engineered by Bosch Rexroth Indramat for the MKE Synchronous Motors series. Intended for potentially explosive areas, it supplies regulated mechanical power to automation cells that must meet explosion-protection rules. The motor’s UL/CSA housing encloses insulation class 155 F windings and is rated for operation from 0 °C to +40 °C. A plain shaft with a frontal centering hole transmits torque, and cabling exits on the A-side through a sealed terminal box that supports the specified connection direction.
At a 60 K winding temperature rise, the stator produces 12.0 Nm of continuous stall torque while drawing a steady current of 9.8 A. For transient moves, the drive can supply up to 44.3 A RMS, allowing the electromagnetic system to reach a peak torque of 43.5 Nm. Speed capability tops out at 4500 rpm, so the winding is suited to dynamic indexing tasks. Winding code 047 combines 8.400 Ω of phase resistance with 1.20 mH of inductance, and these values influence the electrical time constant that filters inverter pulses. The 6.7 nF discharge capacity shunts common-mode voltage, and the terminal box layout keeps creepage distances compliant. Because the motor has no integrated brake, deceleration energy must be dissipated externally.
Low inertia is provided by a rotor mass moment of 0.00430 kg·m², giving short acceleration times without overloading the mechanical coupling. Torque builds at a rate of 1.41 Nm/A, and the back-EMF constant of 91.0 V per 1000 rpm indicates the voltage margin the converter must reserve at maximum speed. The unit weighs 18.0 kg in its brakeless configuration, which keeps the motor manageable in confined enclosures. Airborne sound stays within 61.8 dB[A] ±3, and the DIN 332 DS shaft thread simplifies attachment of locking elements. Compatibility with hazardous-area requirements is supported by the plain shaft seal, which restricts gas ingress along the journal.
