Product Description:
The MKE098B-047-GP1-AUNN is a three-phase servo motor manufactured by Bosch Rexroth Indramat and assigned to the MKE Synchronous Motors series. Built for installation in potentially explosive areas, the unit combines a flame-proof housing with UL and CSA conformity so that it can be driven by Rexroth inverters within hazardous industrial zones. By transforming controlled stator currents into rotor torque, the motor provides precise position and velocity control for automated valves, mixers, and conveyor axes that must meet strict safety codes.
At a 60 K winding temperature rise, the motor sustains a continuous torque of 12.0 Nm while drawing 9.8 A. The torque produced per ampere follows the constant of 1.41 Nm/A, allowing the drive to predict load behavior in current-regulated loops. When momentary overloads occur, the stator can accept a maximum current of 44.3 A, enabling a peak torque output of 43.5 Nm for acceleration or disturbance rejection. Mechanical speed is limited to 4500 rpm, a ceiling that protects the bearings and prevents excessive back EMF, which is characterized by a voltage constant of 91.0 V per 1000 rpm. The 1.20 mH winding inductance and 8.400 Ω resistance shape current rise times, and a 6.7 nF discharge capacity diverts common-mode surges through the protective earth.
The allowable ambient range of 0 to +40 °C lets the motor reach rated output without external cooling inside standard cabinets. Dynamic response is supported by the rotor moment of inertia of 0.00430 kg·m², which balances low overshoot with stable load coupling. Net mass remains moderate at 18.0 kg, easing vertical mounting in confined spaces. An 11 Nm holding brake secures vertical axes during power loss, and connections are routed on the A-side through a sealed terminal box. A shaft with a DIN 6885 keyway transmits torque, and a shaft seal helps block lubricant migration. Sound pressure of 61.8 dB[A] keeps noise within typical factory limits, while the F-class insulation endures winding temperatures up to 155 °C.
