Product Description:
The MKE118D-027-BG0-KE4 synchronous motor is produced by Bosch Rexroth Indramat within the MKE Synchronous Motors series. Its flame-proof housing meets ATEX requirements, and a plain shaft allows straightforward mechanical coupling. The motor drives automated machinery where precise torque and speed regulation are needed, and it is supplied without a holding brake so external mechanisms must secure any axis after power removal.
At a 60 K stator rise the motor delivers a continuous torque of 48.0 Nm while drawing 22.1 A at standstill. For acceleration peaks the shaft can reach 187.0 Nm, and rotor speed is permitted up to 3000 min⁻¹. A torque constant of 2.52 Nm/A links these values to drive current, whereas the 154.5 V-per-1000 min⁻¹ voltage constant defines back-EMF behavior. The 027 winding variant presents 5.70 mH of inductivity and 0.350 Ω of resistance at 20 °C, shaping current dynamics and copper losses. Class 155 F insulation supports continuous duty in ambient temperatures from 0 °C to 40 °C, and the 20.2 nF discharge capacity must be grounded to limit shaft voltage. Encoder feedback is provided by an optical single-turn EnDat 2.1 device.
For short-term overloads the inverter may supply up to 99.6 A, and the rotor inertia of 0.03620 kgm² defines the resulting angular acceleration. Despite a mass of 65.0 kg, positioning remains quick because friction is minimized by the plain shaft, its DIN 332 “DS” thread, and a frontal centering hole. An enclosure rated to IP 65 plus a shaft seal blocks dust and water jets, while cable glands sized 13 – 16 mm feed conductors into the terminal box that is mounted on the top of the frame. The S2 encoder supplies 2,048 increments, sound pressure remains at 61.1 dB[A], and connection hardware follows the ATEX-approved terminal-box format.
