Product Description:

The MKE098B-047-FP1-BE0N is a synchronous servo motor from Bosch Rexroth Indramat that belongs to the MKE Synchronous Motors series. Classified as a servo motor for potentially explosive areas, it drives position-controlled axes in chemical mixers, packaging lines, and printing presses without introducing ignition sources into the workspace. By converting regulated drive current into precise mechanical rotation, the unit serves as the actuator in closed-loop speed or position control systems used throughout industrial automation.

The motor uses winding code 047, with a winding resistance of 8.400 Ω and an inductance of 1.20 mH that affect current rise and commutation behavior. A discharge capacity of 6.7 nF helps manage common-mode voltages at the drive output. The back-EMF slope is 91.0 V per 1000 rpm, while the torque constant is 1.41 Nm/A, allowing predictable torque generation from drive current. With a 60 K housing temperature rise, it can sustain a continuous current of 9.8 A at standstill and deliver a continuous torque of 12.0 Nm. For short overloads, the shaft produces up to 43.5 Nm, and speed may be commanded to 4500 rpm without exceeding mechanical limits.

The cast housing conforms to ATEX requirements, and insulation class 155 F supports winding thermal endurance in ambient temperatures from 0 to +40 °C. Power and feedback cables exit on the B-side through a sealed terminal box, and a shaft seal is fitted to maintain the protection level when the keyed shaft, machined to DIN 6885, interfaces with couplings. An integrated holding brake supplies 11 Nm of static torque for vertical loads. Dynamic peaks are limited by a maximum current of 44.3 A, while the rotor inertia of 0.00430 kg·m² and a mass of 18.0 kg affect system response and help keep the sound pressure level to 61.8 dB[A] ±3.
