Product Description:
The MKE098B-058-CG1-BUNN is a synchronous servo motor built by Bosch Rexroth Indramat for the MKE Synchronous Motors series. Approved for hazardous areas, it converts electrical energy into precisely regulated torque and speed for automation axes in packaging, filling, and material-handling systems. It is typically paired with IndraDrive controllers in machine sections where equipment must be suitable for potentially explosive environments. This makes the motor useful where accurate motion control and protected installation requirements have to be addressed in the same axis.
At standstill, the motor draws a continuous phase current of 12.4 A and delivers 12.0 Nm of torque, while the 058 winding has a resistance of 5.80 Ω and an inductance of 0.740 mH. For short-duty peaks, the drive may supply 55.9 A, pushing output up to 43.5 Nm, and mechanical speed is limited to 5000 rpm. This operating range gives the axis stable low-speed torque with additional headroom for brief acceleration demands. The voltage constant is 70.0 V/min⁻¹, and the discharge capacitance is 6.7 nF, both of which affect drive matching and electrical behavior. Encoder model M1 provides 128 counts of optical multi-turn feedback through the Hiperface interface, so the controller can track rotor position with continuous electronic feedback. Insulation class 155 F, UL/CSA housing compliance, an ambient range of 0 to +40 °C, and a sealed terminal box on the B-side support regular industrial operation.
The mechanical build features a plain shaft with a frontal centering hole, a DIN 332 “DS” thread, and a shaft seal that helps protect the bearing set from contamination. The shaft arrangement supports direct coupling, and the centering hole assists with accurate alignment during assembly. Rotor inertia is 0.00430 kgm², which supports responsive speed changes, and the integrated brake holds 11 Nm when power is removed. A torque constant of 1.09 Nm/A links commanded current to developed torque for closed-loop control. Operating noise remains at 61.8 dB[A], and the frame weighs 18.0 kg before the brake is fitted.
