Product Description:
The MKE098B-047-NP0-BUNN servo motor is produced by Bosch Rexroth Indramat for the MKE Synchronous Motors series. Designed for potentially explosive areas, it converts drive controller current into controlled mechanical motion on actuators, gantries, or mixers that operate inside zone-rated enclosures. Its construction follows UL and CSA housing standards, allowing installation in North American automation lines without additional field approval, and the terminal box on side B streamlines armored cable routing through protected cable glands.
With a 60 K winding temperature rise, the motor can deliver a continuous torque of 12.0 Nm while drawing only 9.8 A of standstill current, providing a workable torque-to-current ratio for tight position loops. During brief overloads, the drive may supply up to 43.5 Nm of peak torque and 44.3 A of RMS current so short acceleration tasks can be completed without stalling. A torque constant of 1.41 Nm/A at 20 °C links controller phase current to shaft torque, which helps the amplifier produce predictable output during positioning and speed control. Internally, phase inductance is 1.20 mH, phase resistance is 8.400 Ω, and discharge capacity is 6.7 nF, which shapes the electrical response during switching. The Class 155 (F) insulation system supports these electrical loads without thermal breakdown.
Mechanical performance is led by a top speed of 4500 rpm and a rotor inertia of 0.00430 kg·m², so the axis can combine fast index moves with limited overshoot. The shaft has a keyway machined to DIN 6885, a shaft seal is fitted, and the motor weighs 18.0 kg, which affects coupling selection and bearing loads. The shaft seal also helps limit contaminant entry at the output interface during operation. Operation is permitted from 0 to +40 °C, and derating is required outside that range. The motor is supplied without a holding brake, produces 61.8 dB[A] sound pressure at rated speed, carries winding code 047, and has a voltage constant of 91.0 V per 1000 rpm for back-EMF calculation.
