Product Description:
The MKE098B-047-CP0-BUNN is a servo motor for potentially explosive environments produced by Bosch Rexroth Indramat within the MKE Synchronous Motors series. Electrical connections are routed on the B-side through a terminal box, and the rotor transmits motion through a shaft with a DIN 6885 keyway. The unit is supplied without a holding brake, has a UL/CSA-compliant housing, and uses Class F insulation rated for 155 °C to tolerate elevated winding temperatures. It is intended for position- or speed-controlled axes in industrial automation where ignition-source-limited hardware is required.
At a 60 K winding temperature rise, the motor can deliver a continuous torque of 12.0 Nm while drawing 9.8 A RMS. This operating point comes from the 047 winding, which has an inductance of 1.20 mH and a resistance of 8.400 ohms. The copper stack also has a discharge capacity of 6.7 nF, which can affect drive-side filter selection. For dynamic control, the torque constant is 1.41 Nm/A and the back-EMF constant is 91.0 V/min⁻¹. Position feedback is provided by an optical multiturn absolute Hiperface encoder, model M1, with 128 increments per revolution. The sound pressure level during nominal operation is 61.8 ±3 dB[A].
For short bursts, the drive can supply a maximum torque of 43.5 Nm by allowing up to 44.3 A of current, and the mechanical output speed can rise to 4500 rpm. With that capability, the 18.0 kg rotor-stator assembly, which has a rotor moment of inertia of 0.00430 kg·m², supports rapid indexing without excessive load on the gear train. A shaft seal is fitted to limit oil or dust ingress, and rated operation is maintained across an ambient range of 0 to +40 °C. The B-side connection arrangement reduces wiring strain, while the optical encoder retains multiturn position data after power loss.
