Product Description:
The MKE098B-047-AP0-BUNN servo motor is produced by Bosch Rexroth Indramat for the MKE Synchronous Motors series and is intended for potentially explosive areas. It uses a UL/CSA-compliant housing and operates in ambient temperatures from 0 °C to +40 °C. Mechanical output is delivered through a shaft with a keyway that follows DIN 6885, and a shaft seal is fitted to limit ingress. The unit is supplied without a holding brake, and the power and feedback conductors enter a terminal box on the B-side. Position feedback comes from an optical single-turn Hiperface encoder, model S1, that provides 128 increments per revolution, while a 6.7 nF discharge capacity helps reduce conducted noise. This feedback arrangement gives the drive rotor position information for closed-loop motion. Sound pressure during operation is 61.8 dB(A) ±3, the motor weighs 18.0 kg, the insulation system meets Class 155 F, and winding code 047 is used for the stator.
Under thermal equilibrium at 60 K, the motor supplies a continuous torque of 12.0 Nm while drawing 9.8 A of phase current, which indicates the steady-state load point for use with a compatible drive. The electromagnetic circuit delivers torque in direct proportion to current with a constant of 1.41 Nm/A, giving the controller a linear response. For rapid indexing, the inverter can source up to 44.3 A RMS, enabling acceleration toward the top speed of 4500 rpm. That current reserve supports short bursts of acceleration during speed changes. The resulting back EMF follows a voltage constant of 91.0 V per 1000 rpm.
Fast motion cycles are aided by a rotor moment of inertia of 0.00430 kg·m², allowing the shaft to reach the peak torque of 43.5 Nm with controlled acceleration. Electrical dynamics are set by a stator inductance of 1.20 mH and a phase resistance of 8.400 ohms at 20 °C, which lets the drive predict current rise and copper losses. The listed electrical values also help the control loop respond consistently during repeated start, stop, and reversal sequences. This combination supports predictable acceleration and braking in hazardous-area servo axes.
