Product Description:

The MKE118B-024-NG1-KE4 is a servo motor manufactured by Bosch Rexroth Indramat for the MKE Synchronous Motors series. It is intended for closed-loop motion in hazardous production zones, where it converts drive current into precise rotary output for mixers, conveyors, and material-handling axes. A plain shaft, an integrated holding brake, and a frontal centering hole simplify coupling to gearboxes or load flanges while supporting accurate positioning during process automation.

At a 60 K winding temperature rise, the motor delivers a continuous torque of 28.0 Nm with a standstill current of 15.3 A. During dynamic operation, it can reach 102.0 Nm maximum torque and draw up to 69.1 A RMS from the drive. The motor has a torque constant of 2.12 Nm/A, and its voltage constant is 130 V per 1000 rpm. This electrical behavior supports speed regulation up to 4000 rpm. Winding code 024, together with a resistance of 7.60 Ω, an inductance of 0.580 mH, and a discharge capacity of 10.3 nF, matches the electrical data used by the drive controller. A rotor inertia of 0.01940 kg·m² helps limit overshoot during rapid reversals. Power and feedback lines enter through a top-mounted terminal box that accepts 13.0 to 16.0 mm cable glands, while insulation class 155 (F) permits elevated copper temperatures. The plain shaft includes a DIN 332 DS thread, a shaft seal is fitted, and the housing has a sound pressure level of 61.1 ±3 dB[A].

A factory-installed holding brake provides 32 Nm of braking torque to secure static loads when power is removed, supporting installations that follow ATEX requirements. The motor operates at ambient temperatures from 0 to +40 °C without derating, and its mass of 45.0 kg adds thermal stability during intermittent duty. The shaft seal, plain shaft geometry, and DIN-compliant thread support installation in pressurized or purged enclosures. These features also help the motor fit applications where secure load holding and protected shaft interfaces are required.
