Product Description:
The MKE098B-047-CG0-BENN is a servo motor manufactured by Bosch Rexroth Indramat as part of the MKE Synchronous Motors series. Designed for use in potentially explosive areas, it uses an ATEX-compliant housing for paint lines, chemical mixers, and grain-handling equipment where combustible atmospheres may be present. When paired with an IndraDrive controller, it provides precise rotary motion and closed-loop torque control for regulated machine axes. This arrangement supports accurate speed and position behavior in processes that need both motion control and protected motor construction.
Under standstill conditions with a 60 K winding rise, the motor delivers 12.0 Nm while drawing 9.8 A. It can reach peaks of 43.5 Nm at 44.3 A, and the operating speed can rise to 4500 rpm. A torque constant of 1.41 Nm/A relates current to output torque, while a voltage constant of 91.0 V/min⁻¹ indicates the back EMF generated by the winding. Thermal and electrical data for winding 047 include 1.20 mH inductance and 8.400 Ω resistance. Position feedback comes from an optical multi-turn absolute Hiperface encoder, model M1, with 128 increments. Cables exit on the B-side through a terminal box, and the plain shaft uses a frontal centering hole, a DIN 332 "DS" thread, and a shaft seal. The motor also uses insulation class 155 F, has a 6.7 nF discharge capacitance for EMC, and emits 61.8 dB(A) of noise.
Rotor inertia of 0.00430 kgm² supports quick acceleration and stable response with light to medium loads. An overall mass of 18.0 kg adds installed rigidity and can help reduce vibration in the machine structure. Safe operation is permitted at ambient temperatures from 0 to +40 °C, and operation outside this range requires derating. Because the motor has no holding brake, vertical axes need an external clamping or holding method during power loss. The shaft seal helps limit contaminant entry around the drive end, and the stated noise level can be considered when setting workplace sound limits.
