Product Description:
The MKE098B-047-DG1-BUNN is a servo motor produced by Bosch Rexroth Indramat for the MKE Synchronous Motors series. As a servo motor for potentially explosive areas, it complies with UL and CSA housing standards and is rated for ambient temperatures from 0 to +40 °C. The unit weighs 18.0 kg without its brake and uses a plain shaft with a frontal centering hole, a DIN 332 DS thread, and an installed shaft seal that supports splash-tight mounting. A factory-fitted holding brake provides 11 Nm of static torque so vertical loads can be secured during power-off conditions.
At standstill, the motor delivers a continuous torque of 12.0 Nm while drawing a continuous current of 9.8 A, both referenced to a 60 K winding temperature rise. Its electrical characteristics include winding code 047, a resistance of 8.400 ohms, and an inductance of 1.20 mH, which shape current response and support a torque constant of 1.41 Nm/A. During acceleration peaks, the drive may reach a maximum torque of 43.5 Nm, along with a voltage constant of 91.0 V min⁻¹ and a discharge capacity of 6.7 nF that helps limit common-mode noise. Sound pressure is 61.8 dB[A] (±3), which keeps operating noise at a moderate level in machine areas. Insulation class 155 (F) permits winding temperatures up to 155 °C.
Speed capability extends to 4500 rpm, and the inverter may supply up to 44.3 A RMS during short duty cycles. A rotor inertia of 0.00430 kgm² supports rapid response while maintaining stable regulation. The M2 feedback system is an optical multi-turn absolute EnDat 2.1 encoder with 2,048 increments per revolution, supporting fine positioning when gas or dust may be present. Power and signal conductors exit on the B-side through a sealed terminal box, and the sealed output end helps prevent lubricant escape. This rearward wiring orientation helps when front access is obstructed.
