Product Description:
The MKE098B-047-GG1-BENN is a servo motor built by Bosch Rexroth Indramat for the MKE Synchronous Motors series. Designed for potentially explosive areas, its ATEX-compliant housing permits safe operation in zones where flammable gases or dust are present. In industrial automation, the unit delivers precise closed-loop rotary motion for drives, positioning tables, or mixers that must operate inside hazardous-area enclosures. This makes it suitable for process equipment that requires ignition protection together with accurate servo performance.
Electrical ratings describe the motor's behavior in continuous duty and short bursts. At standstill, it can draw a continuous current of 9.8 A and produce 12.0 Nm of holding torque while winding temperature rises by only 60 K. For rapid load changes, the drive may deliver up to 44.3 A RMS, enabling a peak torque of 43.5 Nm and speeds up to 4500 rpm. Operation is permitted between 0 °C and +40 °C, and insulation class 155 F provides thermal margin. The built-in 11 Nm holding brake secures the load when power is removed, while a capacitance value of 6.7 nF helps reduce voltage spikes on the controller side. Connections are routed on the B-side through a sealed terminal box, which helps preserve the ATEX barrier and keeps the sound pressure level at 61.8 dB[A].
The motor's dynamic response is influenced by its mechanical and electromagnetic constants. A rotor inertia of 0.00430 kg·m² supports fast acceleration with stable speed control. A torque constant of 1.41 Nm/A and a voltage constant of 91.0 V/min⁻¹ support predictable current demand and back-EMF behavior in vector drives. Winding 047 has an inductance of 1.20 mH and a resistance of 8.400 Ω, which affect current rise time and copper loss. Overall mass is 18.0 kg, and the plain shaft includes a frontal centering hole, a DIN 332 DS thread, and a factory-installed shaft seal for gas-tight coupling.
