Product Description:
The MKE098B-047-KP1-AUNN is a servo motor produced by Bosch Rexroth Indramat within the MKE Synchronous Motors series. It is intended for potentially explosive areas and converts electrical energy into regulated rotary motion for automated machinery operating in hazardous gas or dust zones. Explosion-protected construction allows the unit to be installed with Rexroth drive controllers so that conveyors, pumps, or positioning axes can operate safely in Class I or Class II environments. The motor is suited for controlled motion tasks where speed, torque, and stopping behavior must remain predictable in areas with ignition risk.
Electrical performance at rated temperature sets the continuous operating range. With a 60 K winding rise, the motor supplies 12.0 Nm of torque while drawing 9.8 A from the drive. The torque constant is 1.41 Nm/A, and the A-side cabling exits through a sealed terminal box that helps keep wiring organized. The 047 winding has an inductance of 1.20 mH and a resistance of 8.400 ohms, which affect current response and drive tuning. Insulation class 155 F permits copper temperatures up to 155 °C, and the UL/CSA-compliant housing supports North American installation. The motor operates in ambient temperatures from 0 to +40 °C, has a 6.7 nF discharge capacity for EMC, and uses a positive shaft seal.
In short-term operation, the motor can reach a shaft speed of 4500 rpm and deliver up to 43.5 Nm, provided the inverter can supply 44.3 A RMS. The rotor has an inertia of 0.00430 kgm², which supports rapid acceleration while limiting load on couplings and gear stages. A spring-applied holding brake rated at 11 Nm secures loads during power loss, which is useful on vertical axes. Mechanical power is transmitted through a keyed shaft machined to DIN 6885. The motor weighs 18.0 kg and produces a sound pressure level of 61.8 dB(A) ±3 under nominal load, while the explosion-proof housing supports use in hazardous locations.
