Product Description:

The MKE098B-047-KP1-BENN is a servo motor produced by Bosch Rexroth Indramat for the MKE Synchronous Motors series. It is intended for potentially explosive areas and uses an ATEX-compliant housing for operation in zone-rated environments. Electrical termination is routed on the B-side through a terminal box, which helps keep cabling clear of the driven machine. Mechanical output is delivered through a DIN 6885 keyway shaft with a shaft seal to help limit ingress. The permitted ambient operating range is 0 °C to +40 °C. Acoustic emission is measured at 61.8 ±3 dB(A).

At a 60 K winding temperature rise, the motor develops a continuous torque of 12.0 Nm while drawing a continuous standstill current of 9.8 A. These values describe the thermal steady-state load the drive can supply without exceeding insulation class 155 F. Speed reaches up to 4500 rpm, with the upper limit governed by mechanical balancing and bearing life. The torque constant is 1.41 Nm/A, so current commands correspond to predictable shaft torque. For transient motion profiles, the inverter can supply up to 44.3 A RMS to support acceleration beyond the continuous range. Electrical characteristics also include a voltage constant of 91.0 V/1000 rpm, a winding resistance of 8.400 Ω, and a winding capacitance of 6.7 nF.

Short-duty peaks can raise shaft torque to 43.5 Nm, and an integrated holding brake supplies 11 Nm when power is removed. Dynamic response is influenced by a rotor inertia of 0.00430 kgm², which supports quick speed changes without excessive drive effort. The motor weighs 18.0 kg without the brake, which supports stable mounting in vertical or horizontal layouts. With the 047 winding, the motor has an inductance of 1.20 mH. The shaft seal also helps protect internal components during high-speed operation.
