Product Description:
The MKE098B-047-BP1-BENN is a three-phase AC servo motor produced by Bosch Rexroth Indramat and supplied as part of the MKE Synchronous Motors series. It is intended for potentially explosive areas and provides closed-loop motion in hazardous-zone conveyors, mixers, and filling stations. The motor uses an optical feedback device so the automation controller can regulate position, speed, and torque with high accuracy during operation. Because it is built for servo duty, it is suited to equipment that needs repeatable motion and stable response under changing loads.
At standstill, the motor delivers 12.0 Nm and draws 9.8 A, which is its continuous operating point at a 60 K winding temperature rise. For short acceleration or load peaks, it can reach 43.5 Nm, and the drive may supply up to 44.3 A RMS for that transient demand. Winding code 047 has a resistance of 8.400 Ω and an inductance of 1.20 mH, while a torque constant of 1.41 Nm/A links stator current to output torque. These electrical values affect current response and how the motor interacts with the connected drive. The voltage constant is 91.0 V per 1000 rpm, the maximum speed is 4500 rpm, the rotor inertia is 0.00430 kg·m², and the discharge capacitance is 6.7 nF.
The motor uses an ATEX housing for gas or dust zones where ignition sources must be controlled. It maintains rated output in ambient temperatures from 0 to +40 °C and produces a sound level of 61.8 dB(A) ±3. A holding brake provides 11 Nm of torque during shutdown, and the DIN 6885 keyed shaft includes a shaft seal to limit ingress. Power exits through a terminal box on the B-side, and the S2 single-turn optical encoder with EnDat 2.1 provides 2,048 increments for precise synchronization. The assembly weighs 18.0 kg and uses class F insulation for a 155 °C internal winding temperature limit.
