Product Description:

The Bosch Rexroth Indramat MKE098B-058-AP1-BENN belongs to the MKE Synchronous Motors series and is a servo motor for hazardous areas. It converts regulated drive current into precise rotary motion for filling, mixing, and packaging equipment installed in classified zones. The design combines the 058 winding with an ATEX-compliant housing, allowing installation in explosion-proof or pressurized enclosures without separate mechanical barriers. This arrangement supports closed-loop axis control where ignition protection is required together with accurate speed and position response.

At a 60 K winding temperature rise, the motor delivers a continuous standstill torque of 12.0 Nm while drawing 12.4 A, providing a stable operating point for holding or very low-speed duty. A torque constant of 1.09 Nm/A links current to output torque, and a winding inductance of 0.740 mH supports fast current rise for quick speed changes. The rotor can reach 5000 rpm, and short acceleration peaks up to 55.9 A are permitted. A voltage constant of 70.0 V/1000 rpm and a phase resistance of 5.80 Ω shape the electrical response during dynamic operation. Discharge capacitance of 6.7 nF helps limit bearing currents, and an optical single-turn Hiperface encoder with 128 increments per revolution supplies closed-loop position feedback.

An integrated holding brake rated at 11 Nm secures the shaft when power is removed, and peak torque reaches 43.5 Nm to handle short transient loads against the rotor inertia of 0.00430 kg·m². The aluminum housing meets ATEX requirements and uses a shaft with a DIN 6885 keyway and a shaft seal. Power connections enter through a terminal box on side B to simplify cable routing inside enclosed machinery. Operation is permitted from 0 to +40 °C, while Class F insulation tolerates internal hot spots up to 155 °C. The sound pressure level is limited to 61.8 dB(A) ±3, and the net motor mass without the brake is 18.0 kg.
