Product Description:
The MKE118B-024-CP0-KE4 is a servo motor produced by Bosch Rexroth Indramat within the MKE Synchronous Motors series. Designed for hazardous areas, it converts drive power into controlled rotary motion for positioning and speed-regulated tasks in industrial automation systems. The motor uses the MKE platform, which combines flameproof construction with integrated feedback technology for motion axes installed in explosive atmospheres.
Internally, winding code 024 is paired with a resistance of 7.60 Ω and an inductance of 0.580 mH, along with a torque constant of 2.12 Nm/A and a voltage constant of 130.0 V per 1000 rpm. At a 60 K winding temperature rise, the motor can deliver 28.0 Nm while drawing 15.3 A. For short transients, the drive can call on a peak torque of 102.0 Nm with up to 69.1 A. The shaft can reach 4000 rpm, and a discharge capacitance of 10.3 nF helps with EMI suppression. The unloaded mass is 45.0 kg, which supports stable mounting for the rated operating range.
The rotor’s moment of inertia is 0.01940 kgm², which provides a balance between acceleration response and smoother load behavior. Operation is permitted within an ambient range of 0 to +40 °C, and the housing meets ATEX requirements for explosion protection. Noise emission is rated at 61.1 dB[A], helping keep acoustic output relatively low in enclosed equipment spaces. Power and feedback leads terminate in a terminal box mounted on top of the motor, and the cable entry accepts diameters from 13.0 mm to 16.0 mm. The shaft includes a seal to help block dust and oil, and the keyed output follows the DIN 6885 profile for torque-transmitting couplings such as gearboxes or pulleys. Position data is supplied by an M1 optical multiturn absolute Hiperface encoder with 128 increments per revolution, and the winding uses class 155 F insulation to tolerate internal heating. The motor is supplied without a holding brake, so static loads must be secured by an external clamping device.
