Product Description:

The MKE118D-035-BG0-KUN is manufactured by Bosch Rexroth Indramat and belongs to the MKE Synchronous Motors series. Intended as a servo motor for potentially explosive areas, it converts drive output into precisely regulated torque for conveyor, mixer, and positioning duties in hazardous zones. The motor is supplied without a holding brake, so motion retention at zero speed must rely on external mechanics or the drive’s torque-holding function.

At a 60 K winding temperature rise, the motor delivers a continuous current of 29.8 A and produces a continuous standstill torque of 48.0 Nm. For short acceleration bursts, the current can rise to 134.3 A, yielding a peak torque of 187.0 Nm. With a torque constant of 1.87 Nm/A, the drive controller can predict output force from phase current, while a voltage constant of 114.5 V per 1000 rpm indicates the back EMF seen by the inverter. The 035 winding code pairs 3.20 mH of inductance with 0.210 Ω of resistance, balancing dynamic response against copper losses. A discharge capacitance of 20.2 nF and an insulation class 155 F rating support reliable operation under PWM switching. Rotor inertia is 0.03620 kg·m², so speed changes occur without excessive overshoot, and the design maintains thermal stability within an ambient temperature range of 0 to +40 °C.

The enclosure carries an IP65 rating under UL/CSA rules, and power is routed through a terminal box mounted on the top of the housing. Maximum speed reaches 3000 rpm, monitored by an optical S2 encoder that supplies 2,048 increments through a single-turn EnDat 2.1 interface. The motor has a plain shaft with a frontal centering hole, a DIN-332 DS thread, and a shaft seal for leak-tight coupling. Sound pressure stays near 61.1 dB(A) ±3, and total mass is 65.0 kg, supporting rigid mounting plates without additional damping.
