Product Description:
The MKE098B-047-NP0-BENN is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MKE Synchronous Motors series. Classified as a servo motor for potentially explosive areas, it delivers closed-loop torque and speed control to machinery installed in hazardous zones where flammable fumes or dust can accumulate. By providing precise electrical actuation without ignition sources, the unit supports conveyors, mixers, and positioning tables that must meet safety regulations.
At a 60 K winding temperature rise, the motor sustains 9.8 A of continuous current and develops 12.0 Nm of standstill torque. For transients, the drive may supply up to 44.3 A RMS, allowing a peak torque of 43.5 Nm. Speed regulation is possible up to 4500 min⁻¹, while the electromagnetic design yields a torque constant of 1.41 Nm/A, supporting fine current-based control loops. The enclosure fulfills ATEX requirements, so these electrical limits remain valid in zones classified for explosive atmospheres. Capacitive discharge through the frame is 6.7 nF, and Class 155 (F) insulation protects the windings. Operation is permitted between 0 °C and +40 °C ambient. The 047 winding has 1.20 mH of inductance, which helps stabilize current ripple during servo operation.
The rotor moment of inertia is 0.00430 kgm², allowing rapid changes in velocity without excessive drive stress. A back-EMF constant of 91.0 V/min⁻¹ indicates the bus voltage the controller must supply at top speed, and phase resistance of 8.400 Ohm influences copper losses. The motor is delivered without a holding brake, has a shaft with a keyway machined to DIN 6885, and includes a shaft seal to block contaminant ingress. Power and feedback conductors terminate in a terminal box mounted on the B-side. With a mass of 18.0 kg, sound pressure reaches 61.8 dB[A] (±3) during nominal operation.
