Product Description:
The MKE118B-024-NG0-KE4 is a servo motor produced by Bosch Rexroth Indramat within the MKE Synchronous Motors series. It is intended for use in potentially explosive atmospheres, where it drives positioning and process axes that require accurate speed and torque control in continuous production. Its synchronous design allows the drive system to regulate speed and torque with high accuracy in areas where gas or dust ignition risks must be considered. Operation is permitted at ambient temperatures from 0 to +40 °C, and insulation class 155 F helps protect the winding system during long operating periods.
Under a 60 K winding temperature rise, the motor delivers a continuous torque of 28.0 Nm, and its standstill current is 15.3 A. This operating point shows the continuous load level the motor can carry without exceeding its stated thermal rise. Peak demand is limited by a maximum current of 69.1 A, and the motor can run up to 4000 rpm when the connected inverter supports that speed range. A torque constant of 2.12 Nm/A links motor current to shaft output, while the back-EMF gradient is 130.0 V per 1000 rpm. Winding code 024 has a resistance of 7.60 Ω and an inductance of 0.580 mH at 20 °C, and the discharge capacitance is 10.3 nF. Noise emission stays near 61.1 dB(A), which supports use in enclosed machinery without unusually high acoustic output.
The shaft can deliver up to 102.0 Nm during transient overloads, and the rotor inertia of 0.01940 kg·m² helps moderate speed changes when the motor is coupled to heavier loads. Total mass is 45.0 kg, and the mounting arrangement must support that static load. The housing complies with ATEX requirements for installation in Zone 2 or Zone 22 enclosures. Power and feedback conductors enter through a 13 to 16 mm cable gland in a top-mounted terminal box, which supports vertical cable routing. The motor comes without a holding brake, so holding torque must be supplied externally when the axis must remain fixed at standstill. A shaft seal is fitted, and the plain shaft includes a frontal centering hole with a DIN 332 DS thread for positive coupling.
