Product Description:
The MKE098B-047-CP0-BE0N is a servo motor built by Bosch Rexroth Indramat for the MKE Synchronous Motors series. As a servo motor for hazardous areas, it has ATEX-compliant housing that supports closed-loop motion where flammable vapors may be present. It fits directly into automation lines where precise positioning, speed regulation, and torque delivery are required on conveyors, mixers, metering units, or filling equipment in chemical and paint plants. The motor is intended for applications that need controlled motion without sacrificing suitability for these operating environments.
Under winding designation 047, the motor delivers a continuous standstill current of 9.8 A and produces 12.0 Nm of torque when the stator temperature is held 60 K above ambient. The magnetic circuit has a torque constant of 1.41 Nm/A, and the induced back EMF follows a voltage constant of 91.0 V/min⁻¹, which helps current-loop tuning inside the drive controller. At speeds up to 4500 rpm, the rotor can reach process setpoints without losing synchronization, while the 1.20 mH phase inductance and 8.400 Ω phase resistance shape the electrical time constant and limit ripple. Class F insulation with a 155 °C rating handles the thermal stress generated by this excitation during continuous operation.
Peak demands are met with 43.5 Nm of torque and a permissible RMS current of 44.3 A; these transients are absorbed by a rotor inertia of 0.00430 kgm², giving stable acceleration profiles even with sudden load changes. The motor weighs 18.0 kg, includes a shaft seal, and uses a shaft with a DIN 6885 keyway for positive power transmission. Connections exit on the B-side through a terminal box, and the optical multiturn Hiperface encoder, model M1, provides 128 increments for absolute feedback. Operation is permitted from 0 °C to +40 °C ambient, with a capacitance of 6.7 nF and a sound pressure level of 61.8 dB(A) ±3 dB. The design omits a holding brake, so external braking must be provided if the axis must be held at rest.
