Product Description:
The MKE098B-047-AP1-BENN is a servo motor manufactured by Bosch Rexroth Indramat within the MKE Synchronous Motors series. It is intended for motion axes installed in potentially explosive zones and uses an ATEX-compliant housing for operation in areas where ignitable mixtures may be present. The motor has a terminal box on the B-side of the frame, which supports practical routing of power, encoder, and brake conductors. In automated filling, mixing, and painting equipment, it provides closed-loop torque and speed control for precise axis movement.
At standstill, with a 60 K winding temperature rise, the motor draws 9.8 A continuously and produces 12.0 Nm of holding torque at the shaft. Winding code 047 indicates the copper layout and corresponds to a resistance of 8.400 Ω at 20 °C, an inductance of 1.20 mH, and a phase capacitance of 6.7 nF. The motor has a torque constant of 1.41 Nm/A and a back-EMF constant of 91.0 V per 1000 rpm, which supports stable servo regulation up to a peak current of 44.3 A. Under transient load, it can reach 43.5 Nm and a maximum speed of 4500 rpm. Position feedback is supplied by an optical single-turn Hiperface encoder, model S1, with 128 increments. An integral holding brake provides 11 Nm of static brake torque.
The rotor moment of inertia is 0.00430 kg·m², which supports responsive acceleration while maintaining stable load control. The shaft uses a DIN 6885 keyway for connection to standard couplings, and a shaft seal helps prevent lubricant escape in washdown environments. Operating noise remains below 61.8 dB[A] (±3) during use. The motor weighs 18.0 kg without the brake and uses F-class insulation for winding temperatures up to 155 °C. Permitted ambient conditions range from 0 to +40 °C, allowing installation in conveyors, mixers, and agitators without additional cooling hardware.
