Product Description:
The MKE098B-058-CG0-AUNN servo motor is built by Bosch Rexroth Indramat within the MKE Synchronous Motors series. Classified as a servo motor for potentially explosive areas, it converts drive current into controlled rotary motion for zone-rated production lines and material-handling cells. Its housing conforms to UL and CSA rules, and the plain shaft with a frontal centering hole supports direct coupling to gear stages or belt pulleys.
At standstill, the motor can deliver 12.0 Nm while drawing 12.4 A, with both values stated at a 60 K winding temperature rise. Winding code 058 corresponds to the conductor arrangement used for this motor, and it works with a resistance of 5.80 Ω and an inductance of 0.740 mH to influence current response and copper loss. The torque constant of 1.09 Nm/A indicates the relationship between commanded current and developed torque. The voltage constant is 70.0 V per 1000 rpm, which indicates the back EMF the drive must overcome during operation. Internal discharge capacitance is 6.7 nF, and insulation class 155 F indicates the thermal endurance of the stator. An optical multi-turn absolute Hiperface encoder, model M1, provides 128 increments for closed-loop resolution, while power and feedback conductors exit through a terminal box on the A-side. The motor operates in ambient temperatures from 0 °C to +40 °C, and a shaft seal protects the bearing chamber.
During dynamic operation, the motor withstands 43.5 Nm of peak torque, handles up to 55.9 A RMS, and reaches 5000 rpm mechanical speed. A rotor inertia of 0.00430 kgm² helps moderate acceleration so positioning remains quick yet stable. The motor weighs 18.0 kg, and its measured sound pressure level is 61.8 dB(A) ±3. It does not include a holding brake, so external locking is needed when power is removed, and the shaft carries a DIN 332 DS thread for puller tools.
