Internal Product Review
The MKE098B-047-GG0-BUNN is a servo motor for potentially explosive areas with a terminal box connection. Continuous standstill torque of 12.0 Nm and maximum torque of 43.5 Nm give the MKE motor strong low-speed control and confident peak-load response. UL/CSA housing compliance and a shaft seal make the unit a strong choice for hazardous-duty servo applications.

Product Description:
The MKE098B-047-GG0-BUNN is a servo motor for potentially explosive areas produced by Bosch Rexroth Indramat within the MKE Synchronous Motors series. It converts drive current into rotary motion for positioning tasks in automated machinery that must comply with UL and CSA safety rules. A terminal box on side B routes power and feedback conductors, which helps keep the external connection point protected and organized. The plain shaft with a front centering hole connects directly to couplings or gear stages for accurate mechanical alignment. Operation is intended between 0 °C and +40 °C, and the F-class winding insulation helps protect the motor against thermal stress during continuous duty.
Under rated thermal conditions, the motor develops a continuous torque of 12.0 Nm at a continuous standstill current of 9.8 A, providing a steady load point for closed-loop control. When acceleration is required, the drive can call for a maximum torque of 43.5 Nm, and speed commands are permissible up to 4500 rpm. These operating limits are supported by a torque constant of 1.41 Nm/A, so the controller can estimate shaft torque directly from phase current without external sensors. The motor is supplied without a holding brake, so position retention after power loss must be handled by the machine or by active drive torque. This arrangement is common when the driven axis already includes an external locking or load-holding method.
Transient overloads are accommodated by a peak RMS current of 44.3 A, allowing short bursts of power before thermal cutback. Dynamic response is influenced by the rotor moment of inertia of 0.00430 kg·m², and this relatively low value supports rapid starts and stops with responsive acceleration. Electrical time constants remain compact because the winding inductance is 1.20 mH, while a winding resistance of 8.400 Ω helps limit steady-state losses during normal operation. The housing includes a shaft seal, the sound pressure level is 61.8 dB[A], and the complete unit weighs 18.0 kg. The mass and sealed shaft arrangement support installation where stable mounting and protected shaft entry are required.
