Product Description:

The MKE118B-024-NP1-KE4 is a three-phase servo motor produced by Bosch Rexroth Indramat within the MKE Synchronous Motors series. It is intended for use in potentially explosive areas and uses an ATEX-compliant housing for applications such as pumps, mixers, and conveyors in chemical or paint facilities. The terminal box is mounted on top and accepts cable entries from 13 mm to 16 mm, which supports straightforward cable routing in enclosed installations. A shaft with a DIN 6885 keyway transmits power to the load, and an integrated holding brake keeps the axis locked when system power is removed.

At a 60 K temperature rise under continuous stall, the motor delivers 28.0 Nm while drawing 15.3 A, making it suitable for sustained static load conditions. For speed-controlled operation, the rotor reaches 4000 rpm, and short-term demand can raise phase current to 69.1 A during rapid acceleration or load changes. Torque output follows a constant of 2.12 Nm/A, so the current-to-torque relationship remains direct and easy to apply in servo control. Class 155 F insulation supports winding operation within an ambient temperature range of 0 to 40 °C, and a shaft seal helps limit dust ingress around the shaft.

The motor can absorb transient overloads up to 102.0 Nm, which provides added margin during abrupt load spikes. A rotor inertia of 0.01940 kg·m² supports quick changes in speed and direction without making the axis overly sluggish. The phase inductance is 0.580 mH, which helps support tight current-loop response and stable switching behavior in the connected drive. Operational noise is limited to 61.1 dB(A), which helps keep sound output controlled in enclosed machinery. Additional data include a 32 Nm holding brake, a weight of 45 kg without the brake assembly, and top-routed cabling that keeps conduits short inside flameproof enclosures.
