Product Description:

The MKE098B-047-CG0-BUNN belongs to the MKE Synchronous Motors series produced by Bosch Rexroth Indramat. It is a servo motor intended for potentially explosive environments and works with certified drives to move machine axes in hazardous manufacturing zones where controlled motion and approved components are required. Wiring passes through a terminal box on the B-side of the housing, which keeps power and feedback connections enclosed at the motor body. The enclosure follows UL/CSA construction requirements. The plain-shaft motor is supplied without a holding brake and uses insulation class 155 (F) for elevated winding temperatures within an ambient range of 0 to +40 °C.

At standstill, the motor can deliver 12.0 Nm while drawing 9.8 A, allowing precise static positioning when thermal rise is limited to 60 K. During dynamic operation, the shaft can reach 4500 rpm, and under load surges the drive may command up to 43.5 Nm with a momentary phase current of 44.3 A. Winding code 047 corresponds to 1.20 mH of inductance and 8.400 Ω of resistance, which affect current rise time, while a discharge capacitance of 6.7 nF influences conducted emissions toward the drive. The optical multi-turn absolute Hiperface encoder, model M1, produces 128 increments per revolution so closed-loop feedback retains position after power loss. A shaft seal protects the DIN 332 DS threaded plain shaft and its frontal centering hole.

The low electrical torque gradient of 1.41 Nm/A links commanded current to mechanical output, while the rotor inertia of 0.00430 kgm² helps moderate acceleration for smoother motion. An overall mass of 18.0 kg adds thermal mass, and the sound pressure level of 61.8 dB[A] supports installations that must limit acoustic output near the machine. A voltage constant of 91.0 V/min⁻¹ matches the back-EMF expected by the drive, so the electrical response remains consistent with the motor's winding behavior during closed-loop operation across the usable speed range.
