Product Description:
The MKE098B-047-CP0-AUNN is a servo motor built by Bosch Rexroth Indramat within the MKE Synchronous Motors series. Designed for potentially explosive areas, it carries UL/CSA housing approval for installation in North American hazardous zones. The unit is delivered without a holding brake, so the load must be secured by external means when power is removed. When paired with a certified drive, the motor provides controlled rotary motion for conveyors, mixers, and valve actuators that require accurate speed regulation in flammable atmospheres.
It delivers a continuous standstill torque of 12.0 Nm while drawing 9.8 A at a 60 K winding rise. These values indicate the sustained torque available at standstill and the current required at that thermal condition. During short transients, the shaft can reach 43.5 Nm, and mechanical overspeed protection allows operation up to 4500 rpm. Electromagnetic performance is supported by a torque constant of 1.41 Nm/A and a voltage constant of 91.0 V per 1000 rpm. Winding code 047 corresponds to 1.20 mH of inductance and 8.400 Ω of resistance, which the inverter uses for current control. A discharge capacitance of 6.7 nF helps shunt high-frequency interference, insulation class 155 F protects the windings, and the optical multiturn Hiperface encoder provides 128 increments per revolution for absolute position evaluation. A terminal box on the A-side also helps simplify field wiring.
Peak demand is handled with a maximum phase current of 44.3 A, which the drive must supply without exceeding explosion-safe temperature limits. The rotor has a mass moment of inertia of 0.00430 kg·m², giving the motor moderate inertia for indexing moves while helping speed regulation remain stable under changing loads. Total motor mass is 18.0 kg, which supports vibration damping and gives the housing a solid mechanical presence during operation. The permitted ambient operating range is 0 to +40 °C, and the shaft uses a DIN 6885 keyway with a shaft seal to help block vapor entry. During continuous duty, the sound pressure level remains near 61.8 dB[A].
