Product Description:

The Bosch Rexroth Indramat MKE098B-058-AG0-BENN is a servo motor for potentially explosive areas in the MKE Synchronous Motors series. Built with an ATEX-compliant housing, it withstands flammable atmospheres while supplying closed-loop motion in filling, mixing, and painting equipment. The model is supplied without a holding brake, and it routes power and feedback leads through a terminal box on the B-side of the frame, which simplifies armored cable terminations inside hazardous area enclosures.

Its operating window spans an ambient temperature range of 0 to +40 °C, allowing full-load performance without derating. At standstill and with a 60 K winding temperature rise, the motor supplies 12.0 Nm while drawing 12.4 A. Digital feedback is provided by an optical single-turn Hiperface encoder, model S1, which offers 128 increments for position control. A discharge capacity of 6.7 nF supports EMC shielding in cable runs. The motor reaches a maximum speed of 5000 rpm, where the drive can deliver up to 43.5 Nm and accept 55.9 A RMS. A torque constant of 1.09 Nm/A, winding code 058, 0.740 mH inductance, a voltage constant of 70.0 V/min⁻¹, a winding resistance of 5.80 Ohm, and F-class 155 °C insulation set the electrical limits for inverter selection and overload protection.

The mechanical set includes a rotor with 0.00430 kgm² of inertia, which supports rapid acceleration without excessive regenerative energy. The motor has an overall mass of 18.0 kg. It uses a plain shaft with a frontal centering hole and a DIN 332 DS thread, and a shaft seal is fitted to limit dust or oil ingress. This shaft arrangement supports coupling alignment where keyed torque transmission is not required. Sound pressure for this frame size is 61.8 ±3 dB[A]. Low-speed holding increases copper losses, so drive-side current limits should account for the winding resistance.
