Product Description:

The MKE098B-047-CG0-AUNN is a servo motor built by Bosch Rexroth Indramat for the MKE Synchronous Motors series. Designed for potentially explosive areas, it drives rotary axes where standard enclosures are unsuitable. The motor is supplied without a holding brake, uses a plain shaft with a frontal centering hole, and feeds power through an A-side terminal box. UL/CSA housing approval and a shaft seal support North American safety expectations and help limit contaminant entry, while rated ambient temperatures range from 0 to +40 °C.

During continuous operation at 60 K winding rise, the motor can deliver 12.0 Nm of standstill torque while drawing 9.8 A. This combination marks the thermal load point for holding or low-speed duties. A torque constant of 1.41 Nm/A relates commanded current to shaft torque, and a back-EMF factor of 91.0 V/min⁻¹ reflects the voltage generated as speed increases. The winding inductance is 1.20 mH, and the winding resistance is 8.400 Ω, which supports fast current buildup with moderate copper losses. Rotor inertia is 0.00430 kg·m² for short acceleration times in indexing tasks, while winding code 047, insulation class F, and a discharge capacity of 6.7 nF complete the electrical data.

For dynamic peaks, drive current may reach 44.3 A RMS, allowing the motor to produce 43.5 Nm during rapid acceleration or disturbance rejection. These overloads are available up to a maximum speed of 4500 min⁻¹, and the optical multiturn Hiperface encoder with 128 increments per revolution continues to provide absolute position feedback across the speed range. At top speed, the housing emits a sound pressure level of 61.8 dB[A] ±3 dB, which stays within a range commonly accepted in industrial plants. A total mass of 18.0 kg adds rigidity to the assembly, and the DIN 332 DS shaft thread together with the positive shaft seal supports secure coupling to gearheads or process tooling.
