Product Description:
The MKE098B-047-BP0-BUNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MKE Synchronous Motors series. Classified as a servo motor for potentially explosive areas, it is installed on motion axes that require precise speed and torque control while meeting ignition-protection demands. In automated production cells, it converts commanded electrical power into tightly regulated mechanical rotation so positioning stages, mixers, or conveyors can operate safely within hazardous atmospheres.
The motor uses winding code 047 and delivers a continuous standstill torque of 12.0 Nm when the stator temperature is 60 K above ambient. That output is sustained by a continuous current of 9.8 A. A torque constant of 1.41 Nm/A links drive current to output torque, while the voltage constant of 91.0 V/1000 rpm governs back EMF at speed. During acceleration, the motor can reach a peak torque of 43.5 Nm and may draw up to 44.3 A RMS. Its top mechanical speed is 4500 rpm. The motor uses insulation class 155 (F) for thermal performance. Rotor inertia of 0.00430 kg·m² supports fast reversals without excessive drive demand. Electrical behavior is also influenced by 1.20 mH phase inductance, 8.400 Ω phase resistance, and 6.7 nF capacitance.
The motor is rated for an ambient range of 0 to +40 °C, and the housing meets UL/CSA requirements for use in North American installations. Power and feedback cables exit on the B-side through a sealed terminal box, while the shaft key follows DIN 6885 and a shaft seal is installed to help block ingress. No holding brake is fitted, so external locking methods are required for power-off retention. Position feedback comes from an S2 optical single-turn EnDat 2.1 encoder that delivers 2,048 counts per revolution for closed-loop accuracy. Noise emission is limited to 61.8 ±3 dB(A). The motor weighs 18.0 kg, which is relevant for gantry loads and mounting hardware.
