Product Description:
The MKE098B-058-CG0-BENN is a servo motor in the MKE Synchronous Motors series from Bosch Rexroth Indramat. Designed for potentially explosive areas, it meets ATEX housing requirements and provides closed-loop motion in hazardous process zones where flammable gases may be present. A plain shaft with a frontal centering hole and a DIN 332 DS thread simplifies coupling to gearboxes or direct-drive assemblies. The terminal-box connections are routed on the B-side to keep field wiring clear of moving parts.
At standstill, the motor delivers 12.0 Nm of continuous torque with a corresponding continuous current of 12.4 A, and both values are referenced to a 60 K winding temperature rise. When short bursts are required, the drive can reach a peak torque of 43.5 Nm while drawing up to 55.9 A RMS. The rotor can accelerate to 5000 rpm, and the winding code 058 uses 0.740 mH inductance and 5.80 Ω resistance to balance dynamic response with thermal loading. An optical multi-turn absolute Hiperface encoder, model M1, with 128 increments supplies position feedback, and the 6.7 nF discharge capacity is part of the grounding concept required in explosive atmospheres. No holding brake is installed, so the axis must be secured by external means when power is removed.
The rotor inertia is 0.00430 kg·m², which gives the motor moderate load-matching capability without sacrificing responsiveness. Operation is permitted in ambient conditions from 0 to +40 °C, and the F-class insulation supports winding temperatures consistent with that range. A shaft seal is fitted to protect the internal laminations, and the overall mass is 18.0 kg. With a torque constant of 1.09 Nm/A and a voltage constant of 70 V/1000 rpm, drive controllers can predict back EMF and select a suitable bus voltage. The sound pressure level is 61.8 dB(A) ±3 during operation.
