Product Description:
The MKE098B-058-CG0-BUNN is a servo motor engineered by Bosch Rexroth Indramat for the MKE Synchronous Motors series. Classified for use in potentially explosive areas, the unit supplies rotational power to actuators, conveyor drives, or pump modules where flammable gases may be present. Its UL/CSA-compliant housing, F-class insulation, and an ambient temperature range of 0 to +40 °C allow installation inside certified cabinets, while the plain shaft and frontal centering hole simplify coupling to gearboxes or direct-drive machinery.
This motor delivers a continuous standstill torque of 12.0 Nm when the winding temperature is 60 K above ambient, produced with a continuous current of 12.4 A. During normal operation, the encoder system is an optical multi-turn absolute Hiperface model M1 with 128 increments, which tracks position for closed-loop control. Speed control extends up to 5000 rpm, supported by a torque constant of 1.09 Nm/A, so the controller must supply roughly one ampere for each newton-meter of demand. The electromagnetic circuit has a winding inductance of 0.740 mH and a resistance of 5.80 Ω. The drive uses these values together with the 6.7 nF discharge capacitance when tuning current loops. Power and feedback lines exit on the B-side through a sealed terminal box.
Transient events can be absorbed through a maximum torque of 43.5 Nm and a peak current of 55.9 A, which are used for inverter sizing and overload trip settings. The rotor moment of inertia of 0.00430 kg·m² enables rapid acceleration without sacrificing stability, while the shaft seal protects internal components from oil ingress. At 18.0 kg without a brake, the motor meets mounting limits on vertical axes and balances vibration against mass. Connection hardware is DIN 332 DS threaded, and the absence of a holding brake requires external clamping for static loads. The sound pressure level is 61.8 dB(A).
