Product Description:

The MKE118B-058-CP0-KE6 is a servo motor from Bosch Rexroth Indramat's MKE Synchronous Motors series. It is classified for hazardous areas, so it is used where motion control must meet ATEX housing requirements without sacrificing precision. In automated equipment, the unit supplies closed-loop rotary power to machinery operating in hazardous zones while remaining compatible with standard drive controllers used elsewhere in the plant.

At a 60 K housing temperature, the motor can deliver a continuous torque of 28.0 Nm while drawing 28.4 A, and it can reach a peak torque of 102.0 Nm when the drive supplies up to 127.6 A RMS. A torque constant of 1.15 Nm/A links current to shaft output, and the winding's low inductance of 0.170 mH supports fast current transients in positioning loops. The maximum speed reaches 4500 rpm, and the voltage constant of 70 V/1000 rpm works with a winding resistance of 2.20 Ω. Winding code 058, a multi-turn absolute Hiperface encoder identified as model M1, and a discharge capacity of 10.3 nF help the drive process position feedback while managing common-mode currents. The motor has no holding brake, so stopping torque must come from the controller, while the keyed shaft and shaft seal support repeated operation.

A rotor inertia of 0.01940 kg m² provides a balance between dynamic response and load matching, and the motor weighs 45.0 kg without a brake. Operation is permitted from 0 to +40 °C, and an F-class insulation system helps manage internal heating. The aluminum housing meets ATEX requirements and limits noise to 61.1 ±3 dB[A]. Cabling enters through a 17.0-19.5 mm gland into a top-mounted terminal box, which helps with routing in crowded enclosures. The keyed shaft follows DIN 6885, and a shaft seal helps protect the bearings in washdown environments.
