Product Description:

The MKE118B-024-BG0-KE4 is a servo motor manufactured by Bosch Rexroth Indramat and assigned to the MKE Synchronous Motors series. Designed for potentially explosive areas, its ATEX-compliant housing allows installation in hazardous zones where flammable gases or dust may be present. A terminal box mounted on the top of the frame simplifies cable routing through 13 mm to 16 mm entries, and the plain shaft includes a frontal centering hole that follows DIN 332 "DS" thread guidance. The unit is supplied without a holding brake, relies on a shaft seal to limit ingress, and uses an optical single-turn EnDat 2.1 encoder that provides 2,048 increments for position feedback.

The motor produces a continuous standstill torque of 28.0 Nm when a 60 K winding temperature rise is allowed, and this torque requires a steady current of 15.3 A. Each ampere contributes proportional torque because the electromagnetic coupling factor is 2.12 Nm/A. Acceleration reserves are wide, with a peak torque of 102.0 Nm available as long as the inverter can momentarily supply up to 69.1 A RMS. Thermal stress during such peaks is moderated by 0.580 mH phase inductance and 7.60 Ω phase resistance, which shape current rise and copper losses during dynamic loading.

A mechanical top speed of 4000 rpm lets the motor support fast indexing or continuous transport duties, while the rotor inertia of 0.01940 kgm² balances quick response with stable regulation. Operation remains within an ambient range of 0 to +40 °C, matching the F-class insulation capability. The 61.1 dB[A] sound pressure rating assists with acoustic planning, and a discharge capacity of 10.3 nF aids EMC grounding through the frame. Weighing 45.0 kg, the motor uses winding code 024 and can be mounted so the top connections stay clear of washdown or debris paths.
