Product Description:
The MKE098B-047-PP1-BUNN is a synchronous servo motor built by Bosch Rexroth Indramat for the MKE Synchronous Motors series. It is intended for potentially explosive environments, where it converts drive commands into controlled rotary motion for process and material-handling equipment. Winding code 047 identifies the motor’s electrical configuration, and a terminal box on the B-side provides the supply interface. The housing meets UL and CSA requirements, an F-class insulation system protects the stator, and a factory-installed holding brake keeps the shaft locked when power is removed.
Under steady thermal conditions of 60 K, the motor sustains 12.0 Nm of torque while drawing 9.8 A. Peak duty cycles permit up to 43.5 Nm, supported by a maximum RMS current of 44.3 A. The rotor can spin to 4500 rpm, and the torque constant is 1.41 Nm/A at 20 °C, which helps the drive match current to load demand. The winding has a resistance of 8.400 Ω and an inductance of 1.20 mH, which influence the electrical response seen by the inverter during acceleration and load changes. Operation is allowed in ambient temperatures from 0 °C to +40 °C, Class 155 F insulation handles internal hot-spot rise, a discharge capacitance of 6.7 nF supports electromagnetic compatibility, and the sound pressure level is limited to 61.8 dB(A) ±3.
A rotor inertia of 0.00430 kg m² gives the motor moderate acceleration without requiring unusually high current demand from the drive. Net mass without the brake is 18.0 kg, which supports thermal stability while remaining practical for installation. The integrated brake provides 11 Nm of static holding torque, and the shaft uses a DIN 6885 keyway with a shaft seal for torque transfer and fluid protection. Connection hardware remains inside the terminal box, and the approved enclosure arrangement supports use in classified areas.
