Product Description:
The MKE098B-058-DG0-BENN is a servo motor intended for potentially explosive areas and belongs to the MKE Synchronous Motors series from Bosch Rexroth Indramat. As a synchronous servo motor, it converts drive commands into controlled rotary motion for positioning and speed-regulated applications where ignition protection is required. Its flameproof housing meets ATEX requirements, so it can be used in Zone 2 installations in chemical or paint shop machinery. Power and feedback lines enter through a terminal box mounted on the B-side of the frame, while the plain shaft has a front centering hole with a DIN 332 DS thread for precise coupling. The unit is supplied without a holding brake and operates at ambient temperatures from 0 °C to +40 °C.
At a 60 K winding temperature rise, the motor delivers continuous torque of 12.0 Nm while drawing 12.4 A. Its electromagnetic package uses winding code 058, with a resistance of 5.80 Ω at 20 °C and an inductance of 0.740 mH, which influence current response and voltage demand in a compatible drive system. Peak demand is handled with up to 43.5 Nm of torque and an RMS current of 55.9 A, and the rotor can reach 5000 rpm before overspeed protection engages. Class 155 F insulation supports the thermal load, and an M2 optical multiturn absolute EnDat 2.1 encoder returns 2,048 positional increments per revolution for closed-loop control.
The mechanical response is governed by a rotor inertia of 0.00430 kg·m², which supports moderate acceleration profiles for indexing axes. Position control is supported by a torque constant of 1.09 Nm/A, and the generated back EMF is roughly 70.0 V/min⁻¹ at 1,000 rpm. The motor weighs 18.0 kg without the optional brake and produces a sound pressure level of 61.8 dB(A) ± 3 dB during rated operation. A shaft seal protects the internal bearings from dust and coolant splash during use.
