Product Description:
The MKE098B-047-PP0-BUNN is a three-phase servo motor built by Bosch Rexroth Indramat for the MKE Synchronous Motors series. Classified as a servo motor for potentially explosive areas, it delivers closed-loop rotary motion where ignitable gases or dust are present. An aluminum housing that meets UL/CSA standards encloses the windings and bearings, allowing the unit to mount to certified drive systems without an additional ignition source assessment.
Under a stator temperature rise of 60 K, the motor supplies 12.0 Nm of continuous torque while drawing a continuous standstill current of 9.8 A. When rapid acceleration is required, the shaft can reach a peak torque of 43.5 Nm up to a mechanical limit of 4500 rpm. A torque constant of 1.41 Nm/A links output torque directly to phase current, and the voltage constant is 91.0 V min⁻¹ for drive sizing. Winding code 047 uses an inductance of 1.20 mH and a resistance of 8.400 Ω to moderate ripple currents. The laminated core also provides a 6.7 nF discharge capacity that helps control common-mode voltage. Sound pressure reaches 61.8 dB[A] ±3 at nominal speed, and power and feedback cables exit on the B-side through a terminal box for simpler conduit routing in wall-mounted cabinets.
The thermal envelope spans 0 to +40 °C, supported by Class F insulation rated for 155 °C and suited for elevated winding temperatures during heavy duty cycles. A maximum RMS phase current of 44.3 A is permissible for short transients before protective shutdown. Dynamic behavior is aided by a rotor inertia of 0.00430 kg·m², limiting overshoot in positioning tasks, while the bare motor mass of 18.0 kg assists heat dissipation and vibration damping. The output shaft has a DIN 6885 keyway and a shaft seal, and the motor has no holding brake, so stationary loads must be secured by an external clamping device.
