Product Description:
The MKE098B-047-KP0-BUNN servo unit is built by Bosch Rexroth Indramat within the MKE Synchronous Motors series. Designed for use in potentially explosive areas, the motor provides controlled rotary motion for processing lines and material-handling cells. Power and feedback connections pass through a terminal box on side B, and the shaft uses a DIN 6885 key so torque can be transferred to external machine elements without slip. Its enclosure and connection layout support use in machines where sealed routing and predictable mechanical coupling are important.
At a 60 K winding rise, the motor can deliver a continuous torque of 12.0 Nm with a continuous standstill current of 9.8 A. The magnetic system supports a peak torque of 43.5 Nm, and the drive can draw up to 44.3 A RMS during short transient events. A torque constant of 1.41 Nm/A links commanded current to mechanical output, while a back-EMF constant of 91.0 V per 1000 rpm helps match the motor to a suitable drive. Electrical characteristics include 1.20 mH phase inductance, 8.400 Ω phase resistance, and 6.7 nF discharge capacitance. Class 155 F insulation and a UL/CSA-compliant housing support thermal stability, while the motor comes without a holding brake. A shaft seal helps limit dust ingress, and airborne noise is rated at 61.8 dB(A) ±3.
For dynamic duty, the rotor can accelerate to 4500 rpm, and its low rotational inertia of 0.00430 kg·m² supports rapid speed changes without placing excessive demand on the drive amplifier. This response is useful on axes that start and stop often, where quick reversals and short cycle times are required. The 047 winding variant is intended to balance response time against switching losses, and the total motor mass of 18.0 kg gives the assembly a stable mechanical presence during mounting and operation. The permitted ambient operating range is 0 to +40 °C, so incoming air must remain within that band when the motor is installed in enclosed or dust-tight equipment.
