Product Description:

The MKE098B-047-BP0-BENN is a synchronous servo motor produced by Bosch Rexroth Indramat within the MKE Synchronous Motors series. Designed for use in potentially explosive atmospheres, it converts drive-controller output into controlled rotary motion for pumps, mixers, and positioning axes that require ignition-safe operation. Its ATEX-compliant housing supports installation in Zone 1 or Zone 2 machinery, and the synchronous design helps a compatible drive maintain accurate speed and torque during continuous process automation. This makes the motor suitable for process equipment that cannot use open motor designs in areas where flammable gas may be present.

At standstill, the motor can deliver a continuous current of 9.8 A, resulting in a sustained torque output of 12.0 Nm when the winding temperature is held 60 K above ambient. A torque constant of 1.41 Nm/A states how much mechanical torque is produced for each ampere supplied by the inverter. Magnetic behavior is characterized by an inductance of 1.20 mH, while copper losses are influenced by a winding resistance of 8.400 ohms measured at 20 °C. These values affect current response, heat generation, and the motor's ability to hold position at low speed without excessive temperature rise.

Dynamic demands are supported by a peak torque reserve of 43.5 Nm and a maximum mechanical speed of 4500 rpm, while the matching maximum RMS phase current is 44.3 A. Quick acceleration is aided by a rotor inertia of 0.00430 kgm², and a single-turn optical EnDat 2.1 encoder with 2,048 increments supplies position feedback for closed-loop control and repeatable stopping points. The motor weighs 18.0 kg without a brake, operates from 0 to +40 °C, and produces 61.8 dB(A) of sound pressure during operation. Connections exit through a terminal box on side B, and the shaft seal helps protect internal parts so the F-class insulation can retain its electrical strength during prolonged duty.
