Product Description:

The MKE098B-047-AG0-BUNN is a Bosch Rexroth Indramat servo motor in the MKE Synchronous Motors series. It is intended for hazardous areas and supplies regulated rotary motion to automated valves, agitators, or positioning stages in hazardous production zones. An integrated optical encoder transmits rotor position so the drive can close the control loop accurately during operation. The motor is supplied without a holding brake, which reduces axial length and leaves load holding to external mechanical stops when needed.

At a 60 K winding rise, the motor supplies a continuous torque of 12.0 Nm while drawing 9.8 A in ambient temperatures from 0 to +40 °C. Winding code 047 has an inductance of 1.20 mH at 20 °C, and the motor develops a torque constant of 1.41 Nm/A. The inverter may deliver 44.3 A to produce a peak torque of 43.5 Nm. With a voltage constant of 91 V per 1000 rpm, the rotor can reach 4500 rpm. A 6.7 nF discharge capacitance supports EMC control, insulation class F withstands 155 °C, and the sound level is 61.8 dB[A] ±3.

The motor has a smooth shaft with a centering hole on the front face, and a DIN 332 DS thread is tapped into it for extractor screws. A shaft seal helps prevent oil ingress, and power and feedback leads exit on the B-side through a terminal box approved to UL and CSA requirements. The rotor inertia is 0.00430 kgm², and the motor weighs 18.0 kg, which supports moderate acceleration without excessive loading on the machine frame. Position data comes from an S1 optical encoder that provides 128 increments in the Singleturn Hiperface format, allowing absolute angle reporting after power-up. Electrical loss is influenced by a winding resistance of 8.400 Ohm, which contributes to heating under load.
