Product Description:
The MKE098B-047-CG1-BENN is a servo motor produced by Bosch Rexroth Indramat for the MKE Synchronous Motors series. It is intended for potentially explosive areas and uses an ATEX-compliant housing so motion axes in hazardous zones can operate without added external enclosures. The motor delivers electronically commutated torque to rotary machinery, and an integrated optical multi-turn Hiperface encoder provides position feedback. This feedback arrangement allows the connected drive to monitor shaft position continuously during closed-loop speed and positioning tasks.
Winding code 047 is matched to a continuous standstill torque of 12.0 Nm when a continuous current of 9.8 A flows through the stator at a 60 K temperature rise. The motor reaches a top speed of 4500 rpm, and it can handle short-term load peaks up to 43.5 Nm with an RMS current of 44.3 A. The winding inductance is 1.20 mH, while the resistance is 8.400 Ω and the capacitance is 6.7 nF. The torque constant is 1.41 Nm/A, and the back EMF constant is 91.0 V per 1000 rpm. These electrical values support stable current control and predictable speed response in matched servo applications. Position data come from an M1 optical encoder with 128 increments and multi-turn counting, and operating noise is 61.8 ±3 dB[A].
A holding brake supplies 11 Nm of static torque to hold the load when power is removed, and the rotor moment of inertia is 0.00430 kg m². The plain shaft has a frontal centering hole, a DIN 332 DS thread, and a shaft seal, which supports direct coupling where a sealed shaft end is needed. The insulation class is 155 (F), the permitted ambient temperature range is 0 to 40 °C, and the motor weighs 18.0 kg. The housing is aluminum and meets ATEX requirements, which supports use in hazardous locations while also helping dissipate heat during operation.
