Product Description:
Bosch Rexroth Indramat manufactures the MKE118B-024-BG0-KUN within the MKE Synchronous Motors series. It is a servo motor for potentially explosive areas and supplies closed-loop rotary power to automation equipment that must meet hazardous-location directives. The unit has a UL/CSA-verified housing and uses a top-mounted terminal box, allowing installation in pressurized enclosures while keeping conduit routing upward to the drive.
With a 60 K winding rise, the motor produces a continuous torque of 28.0 Nm from a continuous current of 15.3 A. The torque constant is 2.12 Nm/A at 20 °C, so the control amplifier can estimate load from phase current. For short bursts, the winding accepts 69.1 A RMS and develops a peak torque of 102.0 Nm, while mechanical speed is limited to 4000 rpm. The 024 winding variant has 0.580 mH of inductance and 7.60 Ω of resistance at 20 °C, while a voltage constant of 130 V per 1000 rpm aligns with common 600 V DC buses. A discharge capacity of 10.3 nF helps equalize frame potential in high-frequency environments. Position feedback is delivered by an optical single-turn EnDat 2.1 encoder with model code S2, and it supplies 2,048 increments per revolution.
A rotor inertia of 0.01940 kg·m² supports rapid acceleration without demanding oversized drives. The plain shaft includes a frontal centering hole and a DIN 332 DS thread, and a shaft seal is fitted to help restrict dust or fluid ingress; no holding brake is included. Wiring enters from the top, which matches junction boxes mounted above the machine frame. The sound pressure level reaches 61.1 dB[A] ±3 dB, which is suitable for general plant areas. Stator insulation is rated at 155 (F), allowing operation in ambient temperatures from 0 °C to +40 °C. The overall mass is 45.0 kg, and the motor meets North American safety codes for explosive atmospheres.
