Product Description:

The MKE118B-024-PG0-KUN synchronous servo motor is manufactured by Bosch Rexroth Indramat and belongs to the MKE Synchronous Motors series. Designed for use in potentially explosive areas, it provides controlled rotary motion for automated valves, agitators, and conveying axes that operate in hazardous production zones. The unit incorporates winding code 024 and a plain shaft with a frontal centering hole so it can couple directly to gearboxes or driven shafts without additional adapters, simplifying mechanical integration.

At a 60 K winding temperature rise, the motor delivers a continuous torque of 28.0 Nm, maintained by a continuous standstill current of 15.3 A. Insulation class 155 (F) and a UL/CSA housing rating support this operating point in North American installations. During positioning cycles, the rotor can reach 4000 rpm, while the electromagnetic design provides a torque constant of 2.12 Nm/A, allowing the drive controller to estimate load directly from phase current. A maximum phase current of 69.1 A sets the upper limit for inverter sizing and cable selection. The terminal-box connection is routed upward because the connectors are on the top of the housing, and the motor can run in ambient temperatures from 0 to +40 °C. A shaft seal prevents splashed fluids from entering the bearing chamber.

Short-term load peaks are managed by a maximum torque reserve of 102.0 Nm. The rotor moment of inertia is 0.01940 kg·m², which balances quick acceleration with stable speed regulation. The copper windings have an inductance of 0.580 mH; combined with a resistance of 7.60 Ω and a capacitance of 10.3 nF, this helps moderate current ripple when the 130 V/1000 rpm voltage constant produces back EMF. The motor weighs 45.0 kg without a holding brake, and it includes a DIN 332 DS shaft thread. The sound pressure level is 61.1 dB[A], which supports use in gas-zone machinery where controlled acoustic output is required.
