Product Description:

The MKE098B-058-KP0-BENN belongs to the MKE Synchronous Motors series produced by Bosch Rexroth Indramat. Classified as a servo motor for potentially explosive areas, it is built to drive mechanical axes in hazardous industrial zones where precise position and velocity control are necessary. An ATEX-compliant housing, an F-class winding insulation system, and a terminal-box interface mounted on the B-side align the unit with common motion-control layouts while helping reduce ignition risk.

During continuous operation at a 60 K winding rise, the motor draws 12.4 A and delivers a sustained torque of 12.0 Nm. The motor does not include a holding brake, which keeps inertia low when the load already has an external locking element. For short-term overloads, the drive amplifier may supply up to 55.9 A, allowing the rotor to reach a peak torque of 43.5 Nm. The electromagnetic and mechanical design supports rotational speeds up to 5000 rpm, matching high-speed pick-and-place or spindle applications in paint shops and mixing areas. A rotor inertia of 0.00430 kgm² balances quick acceleration with smooth regulation, and winding code 058 corresponds to an inductance of 0.740 mH and a phase resistance of 5.80 Ω for predictable current loops.

The acoustic emission is 61.8 dB[A], which helps keep operating noise relatively low. With a torque constant of 1.09 Nm/A, the motor produces proportional torque per ampere and supports current-based control strategies. Its cast housing, shaft seal, and DIN 6885 keyway provide secure coupling to gearboxes while maintaining a barrier against oil ingress. Weighing 18.0 kg, the unit can be mounted on standard motor plates without additional supports. Continuous service is specified between 0 °C and +40 °C ambient, and a discharge capacitance of 6.7 nF channels static charges away from bearings during variable-frequency drive operation.
