Product Description:
Bosch Rexroth Indramat produces the MKE098B-047-CP1-BENN servo motor in the MKE Synchronous Motors series. The unit is designed for closed-loop motion in hazardous zones, and its flame-proof housing complies with ATEX so it can operate directly in potentially explosive atmospheres. This makes it suitable for servo-driven axes that require precise position control in areas where standard motor enclosures are not acceptable. A terminal box interface placed on the B-side of the frame simplifies field wiring while maintaining the required clearances for installation at ambient temperatures from 0 to +40 °C.
At standstill and with a 60 K winding temperature rise, the motor delivers a continuous torque of 12.0 Nm from a shaft current demand of 9.8 A. The optical multiturn Hiperface encoder provides 128 increments per revolution for absolute feedback that supports closed-loop control up to the mechanical limit of 4500 rpm. Absolute feedback also helps the drive retain position information and supports accurate speed and position regulation during operation. Each ampere supplied produces 1.41 Nm/A of torque, so the drive can predict load behavior accurately. When brief overload is required, the inverter may supply up to 44.3 A RMS. The motor has a phase inductance of 1.20 mH, which affects current rise times and filter design. The stator winding code is 047, and its resistance at 20 °C is 8.400 Ω.
During acceleration or disturbance rejection, the shaft can reach a peak torque of 43.5 Nm without exceeding thermal limits, giving adequate headroom for indexing axes with variable inertia. The rotor inertia is 0.00430 kgm², which balances quick response against vibration transmission in gearless couplings. A total mass of 18.0 kg aids heat dissipation and lowers the center of gravity. An 11 Nm permanent-magnet holding brake secures vertical loads when power is removed, and the integrated shaft seal blocks oil or dust ingress while preserving the F-class insulation. This arrangement is useful where the load must remain in place after power is removed.
