Product Description:

The MKE098B-047-AG0-AUNN is a servo motor built by Bosch Rexroth Indramat for the MKE Synchronous Motors series. It is intended for use in potentially explosive areas, where closed-loop speed and position control is required for equipment such as agitators, coating systems, and other hazardous-zone machinery. The housing follows UL and CSA requirements, and the motor uses a plain shaft with a frontal centering hole so it can be coupled directly to gearboxes or belt drives without extra adapter hardware.

At a 60 K winding temperature rise, the motor develops a continuous standstill torque of 12.0 Nm with a continuous current of 9.8 A. The torque constant is 1.41 Nm/A, which gives the drive a predictable current-to-torque relationship during controlled motion. Winding code 047 is paired with a winding inductance of 1.20 mH and a phase resistance of 8.400 Ω at 20 °C, which supports stable electrical behavior in matching drive systems. Position feedback is provided by an optical single-turn Hiperface encoder with 128 increments in model S1 form. The terminal box is mounted on the A-side, and the shaft can reach speeds of up to 4500 rpm when the application requires higher linear or rotational speed.

For short-term overload demand, the motor can deliver 43.5 Nm of peak torque when the inverter supplies as much as 44.3 A RMS. Rotor inertia is 0.00430 kg·m², which helps the axis respond quickly during acceleration and deceleration. The motor has a mass of 18.0 kg, giving the unit a stable mechanical base once mounted. An integral shaft seal helps retain lubricant, and operation is permitted in ambient temperatures from 0 °C to +40 °C. The motor is supplied without a holding brake, so any power-off holding function must be provided by external mechanical means. Additional electrical data include a discharge capacity of 6.7 nF for EMC consideration and a sound pressure level of 61.8 dB[A] during nominal running.
