Product Description:

The MKE098B-058-CG1-BENN is a synchronous servo motor built by Bosch Rexroth Indramat for the MKE Synchronous Motors series. It is classified as a servo motor for potentially explosive areas, and its housing follows ATEX directives so the device can be mounted in hazardous production zones. Intended for industrial automation, it pairs with drive controllers to deliver closed-loop position and speed control through an optical multi-turn absolute Hiperface encoder with model M1 and 128 increments.

At a 60 K winding temperature, the motor delivers a continuous torque of 12.0 Nm while drawing a continuous standstill current of 12.4 A, which represents its thermal loading point for sustained duty. Dynamic operation is supported by a peak RMS current of 55.9 A, allowing the shaft to reach a maximum speed of 5000 rpm and a peak torque of 43.5 Nm during acceleration. A rotor moment of inertia of 0.00430 kg·m² gives the motor moderate responsiveness while helping maintain stable running. The 18.0 kg frame uses class 155 (F) insulation and can operate in ambient temperatures from 0 to +40 °C without derating, and feedback signals are routed through a terminal box on the B-side for installations that require rigid conduit entry.

Magnetic characteristics come from winding code 058, with a torque constant of 1.09 Nm/A, winding inductance of 0.740 mH, and winding resistance at 20 °C of 5.80 Ω. A voltage constant of 70.0 V/1000 rpm aligns with common 600 V DC buses, while a discharge capacity of 6.7 nF supports EMC compliance. The integrated holding brake provides 11 Nm to secure static loads when power is removed, and the motor has a shaft seal with a plain shaft that includes a frontal centering hole and a DIN 332 DS thread for puller tools. Installation noise remains below the 61.8 dB[A] sound-pressure guideline, which supports use in machinery with strict acoustic limits.
