Product Description:
The MKE098B-047-DG1-BENN is a synchronous servo motor produced by Bosch Rexroth Indramat within the MKE Synchronous Motors series. It is intended for servo duty in hazardous areas where ATEX-compliant construction is required for rotary axis operation. A plain shaft supports direct coupling, and a multi-turn optical encoder provides absolute position data to the controller for closed-loop motion in material-processing and conveying systems. The motor is suited to applications that need controlled speed and position while operating in zones where ignition protection is important.
With a winding temperature rise of 60 K, the motor delivers a continuous standstill torque of 12.0 Nm at a continuous standstill current of 9.8 A. The 047 winding has an inductance of 1.20 mH and a phase resistance of 8.400 ohms, which influence current response during acceleration and holding. For short periods, the motor can reach 43.5 Nm of peak torque, and it uses insulation class 155 (F) with a maximum RMS current of 44.3 A. Feedback is provided by an M2 optical multi-turn EnDat 2.1 encoder with 2,048 increments per revolution, while the electrical connections are routed to a terminal box on the B-side and a discharge capacity of 6.7 nF helps divert shaft voltage to ground.
The motor reaches a maximum speed of 4500 rpm, and its rotor moment of inertia of 0.00430 kg·m² supports quick indexing without excessive inertial load. A torque constant of 1.41 Nm/A works with a back-EMF constant of 91.0 V min⁻¹, which influences the voltage required during high-speed operation. A spring-applied brake provides 11 Nm of holding torque when power is removed, and a shaft seal protects the plain shaft, which includes a DIN 332 DS thread and a frontal centering hole. The motor has a total mass of 18.0 kg, a sound pressure level of 61.8 dB[A] ±3, and a continuous-duty ambient temperature range of 0 °C to +40 °C.
