Product Description:

The MKE098B-047-BG0-BINN is a three-phase synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MKE Synchronous Motors series. It is intended for use in potentially explosive areas where flammable gases may be present and closed-loop positioning is required for conveyors, mixers, or filling equipment. The motor combines servo response with a design suited to controlled motion in hazardous process zones. It is appropriate for applications that require repeatable speed or position while operating in classified environments.

At a 60 K winding temperature rise, the motor supplies a continuous standstill torque of 12.0 Nm and draws 9.8 A. For short-term peaks, it can reach 43.5 Nm and an RMS phase current of 44.3 A. The shaft speed can reach 4500 rpm, and operation is permitted from 0 to +40 °C. The torque constant is 1.41 Nm/A, and the voltage constant is 91.0 V/1000 rpm. Winding code 047 corresponds to an inductance of 1.20 mH and a resistance of 8.400 Ω at 20 °C. Position feedback is provided by an optical single-turn EnDat 2.1 encoder with 2,048 increments. Power and signal conductors exit through a terminal box on side B, and a 6.7 nF discharge capacitance supports electromagnetic compatibility. The motor comes without a holding brake, uses Class F insulation, and includes a shaft seal for ingress protection.

The motor has a plain shaft with a front centering hole and a DIN 332 DS thread. Its mass is 18.0 kg, and rotor inertia is 0.00430 kg·m², which supports moderate acceleration without excessive drive demand. Acoustic emission is limited to 61.8 dB(A), which helps reduce noise in enclosed equipment. The optical encoder, sealed housing, and B-side terminal orientation support installation in explosion-rated drive packages that require precise motion control.
