Product Description:
The MKE098B-047-NP1-BUNN is a servo motor developed by Bosch Rexroth Indramat for the MKE Synchronous Motors series. Classified as a servo motor for hazardous areas, it supplies closed-loop rotary power for conveyors, mixers, and filling machines installed where ignition sources must be strictly limited. Its design supports precise speed and position control in regulated process equipment. This makes it suitable for applications that require dependable motion control in demanding industrial environments.
At standstill, the motor delivers a continuous torque of 12.0 Nm while drawing 9.8 A with a 60 K winding temperature rise, supplying predictable stall capability for positioning axes. During acceleration, it reaches 43.5 Nm and speeds up to 4500 rpm. The 047 winding has an inductance of 1.20 mH and a resistance of 8.400 Ω, so the connected drive must account for moderate electrical time constants. A voltage constant of 91.0 V per 1000 rpm together with 6.7 nF discharge capacitance shapes the back-EMF behavior seen by the inverter. A terminal box on side B supports right-hand cable routing, and the shaft uses a DIN 6885 keyway for positive torque transfer. Operation is permitted between 0 °C and 40 °C inside UL/CSA-compliant housings, and a shaft seal helps limit ingress under those conditions.
Dynamic duty cycles allow an RMS phase current of 44.3 A, and the electromagnetic design provides a torque constant of 1.41 Nm/A, allowing current demand to be matched closely to torque output. An integrated holding brake rated at 11 Nm secures vertical loads when power is removed. The brake contributes to a rotor inertia of 0.00430 kg m², which still supports rapid reversals and stable motion changes. Despite the added brake, the unit weighs 18.0 kg and has a noise level of 61.8 dB(A), which helps keep nearby work areas quieter during operation. Insulation class 155 F and UL/CSA housing certification support use in splash-protected hazardous production environments.
